It was not the fastest, it was not the prettiest, and it could not turn with a Messerschmitt. But when the German offensive broke over France in May 1940, the MB.152 was one of only three modern fighters the Arm\u00e9e de l\u2019Air had in real numbers \u2014 alongside the Morane-Saulnier MS.406 and the excellent Dewoitine D.520 \u2014 and it did the one thing a defensive fighter has to do: it went up, it took punishment, and it shot the enemy down.<\/p>\n<p>The aircraft came from the Soci\u00e9t\u00e9 des Avions Marcel Bloch, the firm of a designer whose name would later become one of the most famous in aviation. After the war Marcel Bloch \u2014 an Auschwitz-era deportee who survived Buchenwald \u2014 rebuilt his company under a new name taken from his brother\u2019s Resistance codename: Dassault. The MB.152 is, in a very direct sense, an ancestor of the Mirage and the Rafale.<\/p>\n<p>Its origins were troubled. The original MB.150 of 1936 was so unpromising that the first prototype could not even leave the ground as built. Redesigned with a stronger, larger wing and a more powerful Gnome-Rh\u00f4ne radial, it finally flew, and the improved MB.151 and MB.152 followed it into squadron service. But the programme was chased the whole way by delays \u2014 an engine that ran hot, propellers and gunsights that arrived late, and a French aircraft industry only half-recovered from a chaotic nationalisation.<\/p>\n<p><em>The result was a fighter that reached the front faster than it reached readiness.<\/em> By the outbreak of war in September 1939 around 120 Bloch fighters had been delivered \u2014 but many stood on their airfields without propellers or working gunsights, unable to fight. When the storm finally broke in May 1940, the MB.152 was still working up.<\/p>\n<p>And yet the men who flew it liked what it could do. It was rugged, built of stressed metal, and it could absorb a startling amount of damage and bring its pilot home. It was stable \u2014 a steady gun platform \u2014 and its armament of two 20 mm Hispano-Suiza cannon and two machine guns hit far harder than the rifle-calibre batteries of the early British fighters. Pilots reported diving into a formation of nine enemy aircraft and coming back with two or three shot down.<\/p>\n<p>That combination \u2014 toughness plus firepower \u2014 is exactly what a defensive interceptor needs, and it is why the MB.152 punched above its reputation. A fighter that can survive being hit and then destroy its target with a single short burst is a dangerous opponent even when it is slower. The MB.152 could not choose its fights the way a faster aircraft could, but when a fight came to it, it was well equipped to win the exchange.<\/p>\n<p>The tragedy is one of arithmetic and timing rather than of the aircraft itself. France needed hundreds of ready, fully-armed MB.152s dispersed across a well-run air-defence system in the spring of 1940. What it had was a smaller number of aircraft, many still being sorted out, flown by an air arm that was outnumbered and out-thought. Put the same aircraft into a better-organised defensive battle \u2014 the Battle of Britain, say \u2014 and its record might read very differently.<\/p>\n<p>The MB.152\u2019s great flaw was not courage or firepower but reach. Its combat range was only around 600 kilometres \u2014 barely enough to patrol, intercept and return. In the fluid, collapsing battle of 1940, where airfields were abandoned and the front moved daily, short legs were a genuine operational handicap. It was also slower and less agile than the Bf 109E, and could not dictate a fight the way a Spitfire or a D.520 could.<\/p>\n<div class=\"pull\">\u201cThey proved to be tough aircraft, able to withstand considerable damage.\u201d \u2014 on the MB.152 in the Battle of France<\/div>\n<p>Across the six weeks of the campaign, MB.152 pilots claimed at least 188 enemy aircraft for the loss of about 86 of their own machines \u2014 a respectable exchange for a fighter that was never quite finished. Nine Groupes de Chasse flew the MB.151 and MB.152, and in the south the type also traded blows with the Italian Regia Aeronautica when Italy joined the war on 10 June.<\/p>\n<p>Then it was over. After the armistice of 22 June 1940 the MB.152 soldiered on in the air force of Vichy France, where six groups still flew it. A batch of MB.151s ordered by Greece \u2014 nine of twenty-five \u2014 reached Athens before France fell and fought the Italians at Elefsina. Later, some airframes were passed to Romania by the Germans, and a handful ended up in Luftwaffe hands as trainers. Almost none survived the war intact.<\/p>\n<p>To understand the MB.152 you have to understand the France that built it. In the mid-1930s the French aircraft industry had been hastily nationalised, its famous private firms folded into regional state combines. The upheaval scattered engineering teams, disrupted tooling and slowed everything down at exactly the moment Germany was rearming at speed. The MB.152 was designed and built inside that chaos, and it shows: a sound aircraft dragged to the front more slowly than its rivals across the Rhine.<\/p>\n<p>There is also a numbers problem that colours the whole story. In May 1940 the Arm\u00e9e de l\u2019Air did not lack aircraft on paper \u2014 it had thousands \u2014 but a large share were obsolete, unserviceable, or, in the MB.152\u2019s case, complete but not yet fitted with the propellers, gunsights and instruments needed to fight. The gap between \u201cdelivered\u201d and \u201coperational\u201d was enormous, and the MB.152 sat squarely in it.<\/p>\n<p>None of this is a defence of French strategy in 1940, which failed comprehensively on the ground. But it reframes the aircraft. The MB.152 was not a bad design that let France down; it was a decent design that France\u2019s industry and planning could not deliver in time or in a finished state. When it was ready and in the air, it fought.<\/p>\n<p>It is easy to file the MB.152 under \u201cFrench failure of 1940.\u201d That is unfair. It was a robust, heavily-armed interceptor delivered late and in the wrong quantities, fighting a battle already being lost on the ground. Judged by what it actually did in the air \u2014 not by the catastrophe around it \u2014 it earned its place among the defenders.<\/p>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">01<\/span><span class=\"gt\">The Bloch MB.152\u2019s origins: from a fighter that would not fly to a front-line interceptor<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>The story begins with a 1934 French air-ministry programme for a modern single-seat fighter (the \u201cC1\u201d requirement). Marcel Bloch\u2019s team responded with the MB.150, an all-metal, stressed-skin, low-wing monoplane with a retractable undercarriage \u2014 thoroughly modern on paper. In practice the first MB.150 of 1936 was overweight and underpowered, and famously failed to fly as originally built.<\/p>\n<p>Rather than abandon it, Bloch\u2019s engineers rebuilt the design around a larger, stronger wing and a more powerful Gnome-Rh\u00f4ne 14N radial. The reworked aircraft flew in 1937, and from it grew two near-identical production fighters: the MB.151, armed mostly with machine guns, and the MB.152, with the heavier cannon armament. The MB.152.01 prototype made its maiden flight on 15 December 1938.<\/p>\n<p>The naming convention within the family is worth untangling, because it causes endless confusion. The base design was the MB.150. The MB.151 and MB.152 were the two production fighters developed in parallel from it \u2014 externally almost identical, differing mainly in armament and detail. The MB.153, MB.155 and MB.157 were later developments. When a source says simply \u201cthe Bloch 152,\u201d it sometimes means the specific MB.152 and sometimes the whole family; the distinction matters for production figures and combat claims alike.<\/p>\n<p>Development ran in parallel with the MB.151. The first pre-production examples appeared in 1938, and refinement of armament, cooling and equipment continued right up to \u2014 and past \u2014 the outbreak of war. This is the classic signature of a rushed programme: the aircraft entered service while it was still being sorted out, so early units effectively completed development on the squadron.<\/p>\n<p>That long gestation matters. The MB.152 that fought in 1940 was a second attempt built on the bones of a failure \u2014 which is exactly why it was rugged and honest to fly, and also why it arrived later and less polished than an aircraft designed cleanly from the start.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">02<\/span><span class=\"gt\">Marcel Bloch becomes Dassault: the MB.152\u2019s remarkable legacy<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>The most extraordinary thing about the Bloch MB.152 is not the aircraft itself but the man whose initials it carries. Marcel Bloch was one of France\u2019s pioneering aircraft designers. During the German occupation he was arrested and deported, and he survived the Buchenwald concentration camp. His brother, General Paul Bloch, had used the Resistance codename \u201cChardasson,\u201d later shortened; after the war Marcel adopted the name Dassault.<\/p>\n<p>Under the name Dassault, the same design house that produced the MB.151 and MB.152 went on to build the Ouragan, the Myst\u00e8re, the Mirage III, the Mirage 2000 and the Rafale \u2014 the backbone of French air power for the rest of the century. Every one of those jets traces its corporate lineage straight back through the modest Bloch fighters of 1940.<\/p>\n<p>The human story behind the name is sobering. Marcel Bloch was Jewish, and after the fall of France he refused to collaborate. He was arrested, held, and eventually deported to Buchenwald, which he survived. That a man could endure that and then return to build the aircraft that would carry French sovereignty into the jet and supersonic age is one of the great personal arcs in aviation history \u2014 and it starts, in industrial terms, with fighters like the MB.152.<\/p>\n<p>It also changes how the MB.152 should be remembered. It is tempting to see it only as an also-ran of 1940. But it was the product of a design house that clearly knew what it was doing \u2014 the same instincts for rugged, well-armed, purposeful aircraft would reappear, refined, in the delta-winged Mirages. The MB.152 is the humble first draft of a very long and very successful story.<\/p>\n<p>So the MB.152 sits at a hinge point: the last generation of a firm called Bloch, and the direct ancestor of everything called Dassault. It is worth remembering that when you look at a Rafale.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">Design &amp; engineering<\/p>\n<h2>How the Bloch MB.152 was built to fight<\/h2>\n<p class=\"lead\">The MB.152 was a study in trade-offs: a heavy, robust airframe and a punishing gun battery bought at the cost of range and agility. Three features defined it.<\/p>\n<p>None of these were exotic for 1940. What set the MB.152 apart was how it balanced them \u2014 durability and firepower first, performance second.<\/p>\n<p>The airframe was thoroughly of its generation: an all-metal, stressed-skin, low cantilever monoplane with a retractable undercarriage \u2014 the same modern formula as the Bf 109, the Spitfire and the D.520. Where earlier French fighters like the D.500 series had been fixed-gear and open-cockpit, the MB.152 was a clean break into the era of the fast monoplane interceptor. Its designers prioritised structural strength and a broad, load-bearing wing over the last few km\/h of speed, and that choice defined the aircraft\u2019s whole character.<\/p>\n<p>Stressed-skin construction was the key modern feature. Instead of a fabric-covered frame, the metal skin itself carried a large share of the structural loads, producing a stiff, strong and reasonably light airframe. It is a technique that demanded good tooling and skilled labour \u2014 precisely the things a disrupted, recently-nationalised French aircraft industry struggled to supply in quantity. The MB.152 was, in that sense, a modern aircraft asking more of its industry than that industry could easily give in 1939\u201340.<\/p>\n<p>The wing did double duty: it carried the fuel, the retractable main gear, and the entire gun battery of two cannon and two machine guns. Concentrating the armament in the wings kept the fuselage clean and the nose free for the big radial, but it also meant the guns had to be harmonised for a chosen convergence range and serviced out in the wing \u2014 a set of trade-offs common to wing-gun fighters of the era. It was a conventional, sensible layout executed to a robust standard.<\/p>\n<div class=\"cards\">\n<div class=\"card\">\n<div class=\"n\">01<\/div>\n<h3>A cannon-and-machine-gun battery that actually hurt<\/h3>\n<p>The typical MB.152 carried two 20 mm Hispano-Suiza HS.404 cannon and two 7.5 mm MAC 1934 machine guns in the wings. Those 20 mm shells were explosive and could tear structure apart \u2014 a decisive advantage over the eight rifle-calibre guns of an early Hurricane or Spitfire, which had to hit a lot to kill. The MB.152 could kill with a short, well-aimed burst.<\/p>\n<\/div>\n<div class=\"card\">\n<div class=\"n\">02<\/div>\n<h3>A tough, all-metal airframe<\/h3>\n<p>Stressed-skin, all-metal construction with a broad, strong wing made the MB.152 genuinely hard to shoot down. Pilots and post-war historians alike singled out its ability to absorb damage and keep flying \u2014 the quality a defensive fighter needs most when it is outnumbered and on the back foot.<\/p>\n<\/div>\n<div class=\"card\">\n<div class=\"n\">03<\/div>\n<h3>The Gnome-Rh\u00f4ne 14N radial \u2014 strength and a stubborn weakness<\/h3>\n<p>Power came from a Gnome-Rh\u00f4ne 14N two-row radial of roughly 1,000\u20131,100 hp (the MB.152 mostly used the ~1,050 hp 14N-25). The radial was robust and simple, but it ran hot; chronic overheating forced a long series of oil-cooler and cowling changes that delayed production and never fully went away.<\/p>\n<\/div>\n<\/div>\n<figure><img data-opt-id=1088435353  data-opt-src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:78--.b845\/w:942\/h:1024\/q:96\/f:best\/https:\/\/migflug.com\/wp-content\/uploads\/2026\/08\/bloch-mb-152-technical-drawing.png\"  decoding=\"async\" src=\"data:image/svg+xml,%3Csvg%20viewBox%3D%220%200%20942%201024%22%20width%3D%22942%22%20height%3D%221024%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%3E%3Crect%20width%3D%22942%22%20height%3D%221024%22%20fill%3D%22transparent%22%2F%3E%3C%2Fsvg%3E\" alt=\"Technical three-view line drawing of the Bloch MB.152\"><figcaption>Technical three-view of the Bloch MB.152.

The engine tended to overheat, and fixing it drove a cascade of changes: different oil-cooler installations were tried, and to avoid yet more delay a large, deep cowling was ultimately adopted to get air through the aircraft. That cowling is one of the type\u2019s most recognisable features \u2014 and it exists partly because the cooling was never elegant.<\/p>\n<p>The Gnome-Rh\u00f4ne 14N itself was a sound and widely-used engine \u2014 versions powered French bombers and other types, and it was rugged and maintainable in the field. The problem was specific to fitting it cleanly into a compact single-seat fighter airframe and getting enough cooling air to it without wrecking aerodynamics. That is a genuinely hard engineering problem, and the MB.152\u2019s slightly bulbous nose is the visible compromise the designers settled on.<\/p>\n<p>Later production and the MB.155 used uprated 14N variants pushing toward 1,100 hp, which improved performance at altitude. But engines were also a national bottleneck: French aero-engine output could not keep pace with airframe production, so even a perfectly-cooled installation would have run into supply limits. The engine story of the MB.152 is, in miniature, the story of the whole French rearmament \u2014 good components arriving too slowly, in too few numbers.<\/p>\n<p>Overheating was not just an engineering nuisance; it was an operational one. It slowed mass production at exactly the moment France needed fighters most, and it contributed to the situation in which, by mid-1940, a large fraction of delivered Bloch fighters were not fully combat-ready. A better-cooled engine would have meant more MB.152s at the front, sooner.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">04<\/span><span class=\"gt\">The MB.152\u2019s short range: the flaw that mattered most<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>If the MB.152 had one decisive weakness, it was range. Its combat radius was built on an internal fuel load that gave it a range of only around 600 km \u2014 enough for point defence but little more. In the collapsing battle of May\u2013June 1940, when airfields were being overrun and the front shifted by the hour, short endurance meant the MB.152 could not loiter, could not escort deep, and could not easily follow a retreating army.<\/p>\n<p>Range shapes everything a fighter can do. A long-legged aircraft like the Dewoitine D.520 (around 1,500 km) could be based flexibly, could patrol a wide area, and could pursue. The MB.152, with roughly 600 km, was tethered to its target: it was a point-defence interceptor whether its commanders wanted one or not. In the mobile, collapsing battle of 1940, where the ideal fighter would have covered a fast-moving front, that limitation bit hard.<\/p>\n<p>It is a useful corrective to the usual \u201cspeed obsession\u201d of fighter comparisons. On top speed the MB.152 was only modestly behind the pack; on range it was in a different, worse category entirely. If you remember one weakness of the MB.152, remember the fuel \u2014 not the airspeed.<\/p>\n<p>The improved MB.155 was developed specifically to address this, with more fuel and greater range, but it came far too late \u2014 only about ten were completed by the fall of France. Range was the MB.152\u2019s Achilles\u2019 heel, and it is the single specification most worth remembering about the type.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">05<\/span><span class=\"gt\">The MB.152 versus the Bf 109E: an honest comparison<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>Against the Messerschmitt Bf 109E, the MB.152 was outmatched on paper. The 109E was faster (around 560 km\/h to the Bloch\u2019s ~509), climbed better, and was more nimble in a fight. A well-flown 109 could choose when to engage and when to leave. The MB.152 could not dictate a fight the same way.<\/p>\n<p>The tactical lesson French pilots learned mirrors what the RAF learned against the same enemy: do not try to dogfight a 109 on its terms. Use height when you can get it, make a firing pass, and use the aircraft\u2019s strengths rather than chasing a turning fight you will lose. The MB.152\u2019s strengths \u2014 a stable gun platform and heavy cannon \u2014 suited exactly that hit-and-recover style.<\/p>\n<p>It is also fair to note what the MB.152 was never asked to do. It did not fly long-range bomber escort, it did not sweep deep into enemy territory, and it did not fight a prolonged campaign like the Battle of Britain. Its war was six intense weeks of home defence. Within that narrow, defensive brief, the performance gap to the 109E mattered less than it would have in any other role.<\/p>\n<p>But the gap was not hopeless. The MB.152\u2019s twin 20 mm cannon gave it a hitting power comparable to the 109E\u2019s own cannon-and-machine-gun mix, and its toughness let it survive hits that would have downed a lighter aircraft. In a defensive battle over home ground, where interception \u2014 not deep escort \u2014 was the job, the MB.152 could trade blows respectably. Its combat record in 1940 bears that out.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">06<\/span><span class=\"gt\">The MB.150 family: MB.151, MB.152, MB.155 and beyond<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>The MB.152 was one member of a family. The MB.151 was the earlier, lighter-armed version (usually four machine guns) and shared the same airframe almost exactly \u2014 which is why period photographs of the two are nearly interchangeable. The MB.152 added the heavier cannon armament and became the main combat version.<\/p>\n<p>The MB.155 deserves a closer look, because it is the fighter the MB.152 should have been. It kept the airframe but added fuel for meaningfully greater range and used an uprated engine for better altitude performance. Had it arrived in 1939 in quantity, the \u201cshort-legged Bloch\u201d criticism would largely evaporate. Instead only about ten were completed before the fall of France \u2014 a perfect, painful example of the right fix arriving far too late.<\/p>\n<p>The MB.157 is the tantalising might-have-been. Completed during the Vichy period with a far more powerful engine, it reportedly demonstrated excellent performance \u2014 genuinely competitive figures \u2014 but the war and the occupation meant it never entered production. In it you can glimpse what the Bloch line could have become had France not fallen; it is the bridge between the modest 1940 fighters and the post-war Dassault jets.<\/p>\n<p>The MB.155 was the logical improvement: a more powerful engine and, crucially, greater range \u2014 but it arrived only in 1940 and barely reached production. Experimental offshoots explored other engines (the MB.153 tested an American Pratt &amp; Whitney Twin Wasp), and the ultimate MB.157, completed under Vichy, showed excellent performance but never entered production. Total family output is commonly put in the region of 600-plus aircraft, of which 482 were MB.152s \u2014 though figures vary between sources and should be treated as approximate.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">07<\/span><span class=\"gt\">The Bloch MB.152\u2019s operating costs: what a 1940 state fighter actually cost<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>Honest answer: the per-aircraft and per-flight-hour costs of the MB.152 are not reliably recorded. It was built under wartime state direction by a recently-nationalised French industry, in francs whose value was collapsing, and the surviving production records were never kept as clean unit-cost figures the way post-war programmes are. Any single euro or dollar figure you see quoted for a 1940 MB.152 should be treated with deep suspicion.<\/p>\n<p>There is a deeper point here about how we compare aircraft across eras. Modern encyclopedia entries love a tidy \u201ccost per flight hour\u201d figure because it lets you rank aircraft on a spreadsheet. For a 1940 state-built fighter that figure is essentially meaningless: there was no commercial market, no standardised accounting, and no post-war programme office to reconstruct the numbers. Presenting a false precision would be worse than admitting the gap, so this page marks both the unit cost and the cost per flight hour as not reliably recorded.<\/p>\n<p>If a comparison is wanted, it has to be structural, not financial. The MB.152 was a single-engine, single-seat, all-metal fighter of conventional layout \u2014 in the same broad build-effort class as the MS.406 or an early Bf 109, and far cheaper in materials and man-hours than a twin-engine bomber. Its scarcity in 1940 was never about money; it was about a disrupted industry that could not turn delivered airframes into finished, armed, flyable fighters fast enough.<\/p>\n<p>What can be said is qualitative: the MB.152 was a mass-production interceptor, cheaper and simpler to build than a large multi-engined aircraft, and its Gnome-Rh\u00f4ne radial was a widely-produced, maintainable engine. Its real \u201ccost\u201d in 1940 was measured less in money than in industrial capacity and time \u2014 the very things France did not have enough of.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">Specifications<\/p>\n<h2>Bloch MB.152 \u2014 full specifications<\/h2>\n<p class=\"lead\">Figures are for a representative production MB.152 and vary between sub-variants and sources; approximate values are marked.<\/p>\n<div class=\"twocol\">\n<table class=\"spec\">\n<caption>Airframe &amp; powerplant<\/caption>\n<tbody>\n<tr>\n<th>Type<\/th>\n<td>Single-seat monoplane fighter-interceptor<\/td>\n<\/tr>\n<tr>\n<th>Crew<\/th>\n<td>1<\/td>\n<\/tr>\n<tr>\n<th>Manufacturer<\/th>\n<td>Soci\u00e9t\u00e9 des Avions Marcel Bloch (later Dassault)<\/td>\n<\/tr>\n<tr>\n<th>First flight<\/th>\n<td>15 December 1938 (MB.152.01 prototype)<\/td>\n<\/tr>\n<tr>\n<th>Service entry<\/th>\n<td>1939; operational in numbers by spring 1940<\/td>\n<\/tr>\n<tr>\n<th>Powerplant<\/th>\n<td>1 \u00d7 Gnome-Rh\u00f4ne 14N two-row radial (mostly 14N-25)<\/td>\n<\/tr>\n<tr>\n<th>Power<\/th>\n<td>~1,050 hp (range ~1,000\u20131,100 hp, variant-dependent)<\/td>\n<\/tr>\n<tr>\n<th>Propeller<\/th>\n<td>3-blade variable-pitch<\/td>\n<\/tr>\n<tr>\n<th>Wingspan<\/th>\n<td>~10.54 m (approx.)<\/td>\n<\/tr>\n<tr>\n<th>Length<\/th>\n<td>~9.10 m (approx.)<\/td>\n<\/tr>\n<tr>\n<th>Number built<\/th>\n<td>482 MB.152 (MB.151\/152\/155 family ~600+; sources vary)<\/td>\n<\/tr>\n<tr>\n<th>Unit cost<\/th>\n<td>Not reliably recorded (WWII state production)<\/td>\n<\/tr>\n<tr>\n<th>Cost per flight hour<\/th>\n<td>Not reliably recorded (WWII-era)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<table class=\"spec\">\n<caption>Performance &amp; armament<\/caption>\n<tbody>\n<tr>\n<th>Maximum speed<\/th>\n<td>~509 km\/h (316 mph); sources ~500\u2013515 km\/h<\/td>\n<\/tr>\n<tr>\n<th>Cruise speed<\/th>\n<td>~450 km\/h (280 mph)<\/td>\n<\/tr>\n<tr>\n<th>Range<\/th>\n<td>~600 km (370 mi) \u2014 short; a key weakness<\/td>\n<\/tr>\n<tr>\n<th>Service ceiling<\/th>\n<td>~10,000 m (33,000 ft)<\/td>\n<\/tr>\n<tr>\n<th>Climb<\/th>\n<td>2,000 m in ~3 min 24 s<\/td>\n<\/tr>\n<tr>\n<th>Empty weight<\/th>\n<td>~2,150 kg (approx.)<\/td>\n<\/tr>\n<tr>\n<th>Loaded weight<\/th>\n<td>~2,800 kg (approx.)<\/td>\n<\/tr>\n<tr>\n<th>Armament (MB.152)<\/th>\n<td>2 \u00d7 20 mm Hispano-Suiza HS.404 cannon + 2 \u00d7 7.5 mm MAC 1934 MGs<\/td>\n<\/tr>\n<tr>\n<th>Armament (MB.151)<\/th>\n<td>Typically 4 \u00d7 7.5 mm MAC 1934 machine guns<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">08<\/span><span class=\"gt\">The MB.152\u2019s armament in detail: two cannon and two machine guns<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>The combat-standard MB.152 carried a mixed battery in the wings: two 20 mm Hispano-Suiza HS.404 cannon \u2014 the same excellent gun France would use across many types \u2014 plus two 7.5 mm MAC 1934 machine guns. The 20 mm rounds were explosive and destructive; two of them firing together delivered a heavy blow in the fraction of a second a fighter pilot actually has a target in his sights.<\/p>\n<p>The engine-mounted cannon (moteur-canon) was a French speciality of the era, used on the D.520 and MS.406, where a single cannon fired through the propeller hub. The MB.152 took a different route with its cannon in the wings, which avoided the hub installation\u2019s complications but introduced the usual wing-gun trade-off: the guns had to be harmonised to converge at a set distance, so the pilot\u2019s best shooting came at a particular range rather than everywhere along the centreline. In practice, for a steady aircraft against bomber-sized targets, this worked well.<\/p>\n<p>The 7.5 mm MAC 1934 machine guns rounded out the battery. They added a useful volume of fire for damaging lighter targets and for \u201cwalking\u201d fire onto a target before the cannon did the killing work. The combination \u2014 two heavy cannon plus two machine guns \u2014 was a thoroughly modern armament fit for 1940, and one of the clearest areas where the MB.152 was ahead of, not behind, its British contemporaries.<\/p>\n<p>This is where the MB.152 genuinely outclassed some of its contemporaries. The early Spitfire and Hurricane relied on eight rifle-calibre machine guns \u2014 accurate and reliable, but requiring many hits to bring an aircraft down. The MB.152\u2019s cannon meant it needed far fewer. Firepower, not speed, was the type\u2019s strongest card.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div class=\"gd\">\n<details>\n<summary><span class=\"num\">09<\/span><span class=\"gt\">Variants and production numbers: reading the MB.152 figures honestly<\/span><span class=\"pm\">+<\/span><\/summary>\n<div class=\"gd-body\">\n<p>Production figures for the Bloch fighters are quoted inconsistently, so treat them as approximate. A commonly cited figure is 482 MB.152s built, with the wider MB.151\/152\/155 family reaching somewhere north of 600 aircraft. By the outbreak of war around 120 had been delivered, but a large share were not combat-ready for want of propellers, gunsights or other equipment.<\/p>\n<p>Delivery timing matters as much as the totals. The commonly-cited figure of around 120 Bloch fighters delivered by the outbreak of war in September 1939 sounds respectable until you learn how many were non-operational. Through the \u201cphoney war\u201d of late 1939 and early 1940, French industry worked to close that gap, but the type was still catching up when the German offensive began \u2014 which is why only a portion of the delivered fleet could actually be thrown into the battle.<\/p>\n<p>The MB.155 \u2014 the longer-ranged improvement \u2014 saw only about ten completed before the fall of France. Where you see a precise-looking total for \u201cthe Bloch 152,\u201d check whether it means the MB.152 alone or the whole family; the two are often conflated. This page uses 482 for the MB.152 and ~600+ for the family, and flags both as estimates.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">In the cockpit<\/p>\n<h2>Flying the Bloch MB.152: steady, strong and honest at the controls<\/h2>\n<p class=\"lead\">Pilots did not describe the MB.152 as a thoroughbred. They described it as dependable \u2014 a machine that did what you asked and forgave a lot.<\/p>\n<div class=\"cards\">\n<div class=\"card\">\n<div class=\"n\">01<\/div>\n<h3>A stable gun platform<\/h3>\n<p>The MB.152 was steady in the air and tracked smoothly onto a target \u2014 exactly what its heavy cannon armament needed. Where a twitchy fighter throws off a gunnery pass, the Bloch held its aim, letting an average pilot make his two 20 mm cannon count.<\/p>\n<\/div>\n<div class=\"card\">\n<div class=\"n\">02<\/div>\n<h3>Rugged and forgiving<\/h3>\n<p>The type\u2019s toughness was not just structural marketing \u2014 pilots trusted it to bring them home after taking hits, and its handling gave clear warnings rather than vicious surprises. For a hastily-trained wartime pilot, that forgiveness saved lives.<\/p>\n<\/div>\n<div class=\"card\">\n<div class=\"n\">03<\/div>\n<h3>Outpaced, not outclassed<\/h3>\n<p>Against the Bf 109E it was slower and less agile, and no amount of pilot skill fully closed that gap. The MB.152\u2019s answer was to fight defensively, use its firepower, and rely on its durability \u2014 not to try to out-turn or out-run an opponent it could not beat on performance.<\/p>\n<\/div>\n<\/div>\n<p>The radial engine shaped the flying experience in ways a liquid-cooled fighter did not. Up front sat a big, air-cooled two-row radial in its deep cowling, giving the MB.152 a blunt, purposeful nose and a characteristic sound and vibration. Radials brought real advantages \u2014 they were less vulnerable to a single hit in a coolant line than the inline engines of the Bf 109 or Spitfire, which could be crippled by one well-placed round. For a fighter whose job was to wade into enemy fire, that robustness was another quiet point in its favour.<\/p>\n<p>Take-off and landing demanded the usual discipline of a powerful 1940 taildragger: watch the swing on the runway, respect the torque, and keep the speed up on the approach. None of this was unusual, but it mattered for the hastily-trained pilots of 1940, and the MB.152\u2019s forgiving nature at the edges of the envelope helped compensate for their inexperience. It was, in the best sense, an aircraft that met an average pilot halfway.<\/p>\n<p>Cockpit accounts emphasise workmanlike ergonomics rather than elegance. Visibility over that deep radial cowling was adequate rather than excellent, and the aircraft demanded respect on take-off and landing as most powerful taildraggers of the era did. But once airborne it settled into a reassuring solidity.<\/p>\n<p>The recurring theme in pilot recollection is confidence. The MB.152 would not win a pure performance contest, but it would let you attack, take the return fire, and get back \u2014 and in the desperate arithmetic of 1940, that mattered.<\/p>\n<p>It is telling that despite its short range and modest speed, MB.152 units did not collapse in the campaign. They flew, they intercepted, and they claimed nearly 188 aircraft. That is not the record of an aircraft its pilots distrusted.<\/p>\n<p>Handling near the stall was another point in the aircraft\u2019s favour. Like its stablemates, the MB.152 tended to give a pilot warning before it let go, and it remained controllable when pushed \u2014 qualities that matter enormously for a young pilot dragged into combat with only a few dozen hours on type. A fighter that bites without warning kills its own side; the MB.152 largely did not.<\/p>\n<p>Ground handling and serviceability drew more mixed comment. The deep cowling and the temperamental cooling meant engine management demanded attention, and the disrupted French supply system meant spares and armourers\u2019 equipment were not always where they should be. Much of the frustration pilots expressed about the MB.152 was really frustration with the system around it \u2014 the missing propellers and gunsights of the \u201cphoney war\u201d months especially.<\/p>\n<p>If the D.520 was the fighter France wished it had built sooner, the MB.152 was the fighter France actually had in numbers \u2014 and it fought like one that knew it.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">In context<\/p>\n<h2>The Bloch MB.152 among its 1940 contemporaries<\/h2>\n<p class=\"lead\">Set beside the fighters it flew with and against, the MB.152 was mid-pack on speed, strong on firepower and durability, and weak on range and agility.<\/p>\n<div class=\"twocol\">\n<table class=\"spec\">\n<caption>Headline figures \u2014 1940 fighter generation (approximate)<\/caption>\n<tbody>\n<tr>\n<th>Bloch MB.152<\/th>\n<td>~509 km\/h; 2 \u00d7 20 mm + 2 \u00d7 7.5 mm MGs; ~1,050 hp; range ~600 km<\/td>\n<\/tr>\n<tr>\n<th>Dewoitine D.520<\/th>\n<td>~535 km\/h; 1 \u00d7 20 mm + 4 \u00d7 7.5 mm MGs; ~910 hp; range ~1,500 km<\/td>\n<\/tr>\n<tr>\n<th>Morane-Saulnier MS.406<\/th>\n<td>~486 km\/h; 1 \u00d7 20 mm + 2 \u00d7 7.5 mm MGs; ~860 hp<\/td>\n<\/tr>\n<tr>\n<th>Messerschmitt Bf 109E<\/th>\n<td>~560 km\/h; 2 \u00d7 20 mm + 2 \u00d7 7.9 mm (typical); ~1,100 hp<\/td>\n<\/tr>\n<tr>\n<th>Supermarine Spitfire Mk I<\/th>\n<td>~580 km\/h; 8 \u00d7 7.7 mm MGs; ~1,030 hp<\/td>\n<\/tr>\n<tr>\n<th>Hawker Hurricane Mk I<\/th>\n<td>~520 km\/h; 8 \u00d7 7.7 mm MGs; ~1,030 hp<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<table class=\"spec\">\n<caption>What the table shows<\/caption>\n<tbody>\n<tr>\n<th>Firepower<\/th>\n<td>Among the best of the group: two explosive 20 mm cannon<\/td>\n<\/tr>\n<tr>\n<th>Speed<\/th>\n<td>Mid-pack \u2014 faster than the MS.406, slower than the D.520 and the Germans<\/td>\n<\/tr>\n<tr>\n<th>Range<\/th>\n<td>Worst of the group \u2014 the MB.152\u2019s defining weakness<\/td>\n<\/tr>\n<tr>\n<th>Toughness<\/th>\n<td>Excellent \u2014 a genuine strong point<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>The comparison makes the MB.152\u2019s character plain. It was not a bad fighter; it was an unbalanced one. Give it the D.520\u2019s range and it would be remembered very differently.<\/p>\n<p>It is also fairer to the MS.406 and MB.152 to remember that both were asked to hold the line while the far better D.520 was still reaching squadrons in tiny numbers. In May 1940 the D.520 fully equipped only about one groupe; the MS.406 and MB.152 carried most of the load.<\/p>\n<p>Against the Regia Aeronautica in the south \u2014 flying older biplanes and the Fiat G.50 and Macchi C.200 \u2014 the MB.152\u2019s cannon and toughness told even more clearly than against the Luftwaffe.<\/p>\n<p>The comparison with the German fighters needs one more piece of honesty. The Bf 109E was not merely a bit faster \u2014 it was flown by an air force with better tactics, better radio coordination and, crucially, the initiative. The MB.152\u2019s performance gap was real, but it was compounded by a strategic and doctrinal gap that no single aircraft could close. Blaming the airframe alone for the outcome mistakes a symptom for the disease.<\/p>\n<p>Set the MB.152 beside the Hawker Hurricane, though, and the picture flatters the French fighter more than popular memory allows: similar top speeds, heavier cannon armament, and comparable toughness. The Hurricane is remembered as a war-winner and the MB.152 as a footnote \u2014 but much of that difference is the story of the two nations\u2019 wars, not the two aircraft\u2019s merits.<\/p>\n<p>The armament column is where the MB.152 quietly shines. Two 20 mm cannon put it among the hardest-hitting fighters of the whole 1940 generation \u2014 heavier in a single burst than the eight-gun British fighters and comparable to the German cannon armament. For a defensive interceptor whose job was to knock down bombers quickly, that mattered more than a few km\/h of top speed.<\/p>\n<p>The one row that damns it is range. At roughly 600 km it is the worst in the table by a wide margin \u2014 less than half the reach of the D.520. Every other shortcoming of the MB.152 can be argued around; this one is simply a fact of the design, and it is the honest reason the type could never have been France\u2019s decisive fighter no matter how many were built.<\/p>\n<p>Judged in its own weight class and its own moment, the MB.152 was a credible interceptor let down by strategy and time, not by design cowardice.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">Timeline<\/p>\n<h2>The Bloch MB.152: a service record in dates<\/h2>\n<div class=\"tl\">\n<div class=\"row\">\n<div class=\"yr\">1934<\/div>\n<div class=\"ev\">The French air ministry issues the C1 single-seat fighter programme that will shape the Bloch fighters.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">1936<\/div>\n<div class=\"ev\">Marcel Bloch\u2019s all-metal MB.150 is completed \u2014 but, overweight and underpowered, it fails to fly as first built.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">1937<\/div>\n<div class=\"ev\">Rebuilt with a larger wing and a Gnome-Rh\u00f4ne radial, the MB.150 flies; it leads to the MB.151 and MB.152.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">15 Dec 1938<\/div>\n<div class=\"ev\">The MB.152.01 prototype makes its maiden flight.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">Jan 1939<\/div>\n<div class=\"ev\">The prototype is refitted and the armament arrangement revised as the design is finalised for production.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">1939<\/div>\n<div class=\"ev\">The MB.152 enters squadron service; production is dogged by engine overheating and late propellers and gunsights.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">Sep 1939<\/div>\n<div class=\"ev\">War breaks out; ~120 Bloch fighters delivered, but many are not combat-ready for lack of equipment.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">10 May 1940<\/div>\n<div class=\"ev\">The German offensive begins; nine Groupes de Chasse fly the MB.151\/152 in the Battle of France.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">May\u2013Jun 1940<\/div>\n<div class=\"ev\">MB.152 units fight hard against the Luftwaffe; pilots claim ~188 aircraft for the loss of about 86 Blochs.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">10 Jun 1940<\/div>\n<div class=\"ev\">Italy enters the war; MB.152s in the south engage the Italian Regia Aeronautica.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">22 Jun 1940<\/div>\n<div class=\"ev\">The armistice ends the campaign; six groups continue to fly the MB.152 in the Vichy French Air Force.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">1940\u201341<\/div>\n<div class=\"ev\">Nine of 25 MB.151s ordered by Greece reach Athens; they fight the Italians at Elefsina until 19 April 1941.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">1942<\/div>\n<div class=\"ev\">As Vichy forces stand down, airframes are passed to the Royal Romanian Air Force; a few reach the Luftwaffe as trainers.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">Post-war<\/div>\n<div class=\"ev\">The type vanishes from service; Marcel Bloch, a Buchenwald survivor, rebuilds his firm as Dassault.<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"yr\">Today<\/div>\n<div class=\"ev\">No complete MB.152 is known to survive intact; components and a partial airframe are associated with French collections (details vary).<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<p class=\"kicker\">Stories &amp; eyewitnesses<\/p>\n<h2>The Bloch MB.152 in twelve stories<\/h2>\n<div class=\"carou\">\n<div id=\"hxtrack\" class=\"track\">\n<div class=\"scard\">\n<div class=\"st\">The designer<\/div>\n<h3>From Buchenwald to the Mirage<\/h3>\n<p>The initials on the MB.152 belong to a man who survived a concentration camp and rebuilt as Dassault.<\/p>\n<details>\n<summary>Read the story<\/summary>\n<p>Marcel Bloch designed the MB.150 family, was arrested and deported during the occupation, and survived Buchenwald.

It is best understood in three overlapping chapters: the Battle of France against the Luftwaffe, the brief southern war against Italy, and the long, diminished afterlife under Vichy and its successors.<\/p>\n<p><b>The Battle of France (May\u2013June 1940).<\/b> This was the MB.152\u2019s real war. Nine Groupes de Chasse flew the MB.151 and MB.152, intercepting German bombers and their fighter escorts as the Wehrmacht drove across the Low Countries and into France. Outnumbered, often operating from fields under threat, and hampered by short range, MB.152 pilots nonetheless claimed roughly 188 aircraft while losing about 86 of their own. The type\u2019s toughness and cannon armament were decisive in making that exchange possible.<\/p>\n<p>The interception mission suited the MB.152 better than any other. German bomber formations \u2014 He 111s, Do 17s, Ju 88s and the Ju 87 Stukas \u2014 were exactly the targets a stable, cannon-armed fighter was built to destroy, and the MB.152 could bore in, absorb defensive fire, and knock them down. The problem was rarely killing the enemy once engaged; it was getting enough ready fighters into the right piece of sky, and then getting them home again before their fuel ran out. Those were failures of quantity and range, not of the aircraft in the fight.<\/p>\n<p><b>The war against Italy (June 1940).<\/b> When Italy declared war on 10 June, MB.152 units in the south faced the Regia Aeronautica. Against older Italian biplanes and the lightly-armed Fiat G.50 and Macchi C.200, the MB.152\u2019s heavy armament and durability were even more effective. This front lasted only days before the armistice, but it added to the type\u2019s tally.<\/p>\n<p>The intensity of the Battle of France chapter is easy to underestimate. In six weeks the type flew a punishing tempo of interception sorties against a numerically superior and technically strong enemy, from bases that were increasingly under threat. Losses of about 86 aircraft were spread across those weeks \u2014 a heavy attrition rate that speaks to how hard the units were worked, not to any fragility in the airframe, which pilots consistently praised for toughness.<\/p>\n<p>It is worth stressing that the MB.152 was fighting a battle whose outcome was decided largely on the ground. No fighter, in any number, could have reversed the collapse of the French army in May\u2013June 1940. The air war the MB.152 fought was therefore a rearguard action from the start \u2014 which makes its positive claim-to-loss record all the more creditable, and its ultimate futility all the more poignant.<\/p>\n<p><b>The Greek episode (1940\u201341).<\/b> The MB.150 family had one small foreign combat career worth telling. Greece ordered 25 MB.151s, but France fell before the order could be filled; only nine reached Greece, and those arrived still being worked up and, by some accounts, short of armament and equipment. Pressed into service at Elefsina, the Greek Blochs fought the Italians during the Greco-Italian War and then the Germans, with the last reportedly shot down on 19 April 1941. It is a footnote, but a genuine combat chapter beyond France\u2019s borders.<\/p>\n<p><b>The Romanian and German coda (1942 onward).<\/b> As Vichy units were disbanded, the German Armistice Commission arranged for surviving Bloch fighters to be passed to the Royal Romanian Air Force, and a small number ended up in Luftwaffe hands in secondary roles such as training. By this point the MB.152 was thoroughly obsolescent, and these transfers were about using up remaining stock rather than fielding a front-line fighter. The type\u2019s combat life, in any meaningful sense, had ended with the armistice of June 1940.<\/p>\n<p><b>Vichy and after (1940\u201342+).<\/b> After the armistice, six groups kept flying the MB.152 under Vichy France. As Vichy\u2019s forces were progressively stood down, surviving airframes were dispersed \u2014 some to Romania via the Germans, a few into Luftwaffe training use. By the mid-war years the MB.152 had effectively left front-line service everywhere.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">The pilots<\/p>\n<h3>The men who flew the Bloch MB.152<\/h3>\n<p>The MB.152 was flown by ordinary Arm\u00e9e de l\u2019Air fighter pilots thrown into an extraordinary crisis. Many were young, hastily trained, and handed a fighter that was itself not fully ready. What comes through their accounts is not despair but grim professionalism.<\/p>\n<p>Pilots consistently praised two things: the aircraft\u2019s toughness and its guns. Stories of diving into a superior enemy formation, firing, absorbing return hits, and still flying home recur across unit histories. The MB.152\u2019s ability to take damage \u2014 a quality easy to overlook next to speed charts \u2014 was, for the man in the cockpit, the difference between a hard day and a fatal one.<\/p>\n<p>They were equally clear about the frustrations: the short range that forced them to break off, the performance gap against the Bf 109E, and the maddening early period when their own aircraft sat unarmed or unpropellered. That the same pilots still produced a positive claim-to-loss record says a great deal about them \u2014 and about the fighter they trusted to bring them back.<\/p>\n<p>The experience of flying the MB.152 in May 1940 was also, inescapably, the experience of a losing campaign. Squadrons moved from field to field as the front collapsed, sometimes flying multiple sorties a day, sometimes abandoning aircraft that could not be evacuated. The tempo was punishing and the strategic picture bleak. In that context the discipline of the MB.152 units \u2014 continuing to intercept, continuing to score \u2014 is a story of professionalism under enormous strain, not of a demoralised force flying a hopeless machine.<\/p>\n<p>Some names did emerge. A number of French aces scored victories on the Bloch fighters, and pilots who flew the MB.151\/152 in 1940 went on to fly with Vichy, with the Free French, or with the reconstituted French air arm later in the war. The scattering of the type across so many fates after June 1940 also scattered its human record, which is part of why a coherent \u201cMB.152 pilot legend\u201d never crystallised the way the Spitfire\u2019s did.<\/p>\n<p>Ground crews deserve a mention too. Keeping the temperamental, hot-running Gnome-Rh\u00f4ne turning through six weeks of intensive operations, often while relocating between threatened airfields, was a feat of improvisation under pressure. The MB.152\u2019s reputation for getting back home rested as much on the mechanics who patched it overnight as on the airframe\u2019s inherent toughness.<\/p>\n<p>Because the MB.152\u2019s war was so short and so overshadowed by the national defeat, few of its pilots became household names the way aces of the Battle of Britain did. That obscurity is part of why the type is under-remembered today \u2014 not because the flying was unremarkable, but because the story around it was catastrophic.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">Divided service<\/p>\n<h3>Vichy France and the Bloch MB.152\u2019s awkward afterlife<\/h3>\n<p>The armistice of June 1940 split France, and split the fate of its fighters with it. The MB.152 became a Vichy aircraft: six groups continued to operate it under the collaborationist government\u2019s air arm, constrained by the terms Germany imposed and largely kept out of serious combat.<\/p>\n<p>This is an uncomfortable chapter, and worth stating plainly. The same MB.152 that had fought the Luftwaffe in May 1940 spent its final active years under a regime that had made peace with Germany. A few examples reached the Free French forces that fought on, but the type\u2019s main post-armistice home was Vichy \u2014 a reminder that the aircraft of 1940 did not simply retire, but were caught up in France\u2019s divided, painful war.<\/p>\n<p>The Vichy air force operated under tight constraints. Fuel was limited, flying was restricted, and the aircraft were kept largely for the defence of Vichy-controlled territory rather than for offensive operations. In that half-life the MB.152 flew little and fought less; it became a garrison fighter for a rump air arm, its guns rarely fired in anger. The contrast with the frantic, high-tempo weeks of May\u2013June 1940 could hardly be sharper.<\/p>\n<p>It is a measure of how completely the war swallowed the type that its designer\u2019s own fate ran in parallel. While the MB.152 idled under Vichy, Marcel Bloch \u2014 the man whose initials it bore \u2014 was moving toward arrest and deportation. Aircraft and maker alike were caught in the machinery of occupied and divided France. That both, in a sense, survived to see 1945, and that the maker went on to greatness, is the redemptive turn in an otherwise bleak middle chapter.<\/p>\n<p>The transfers themselves tell the story of a defeated air arm being picked over. By 1941 the German Armistice Commission was pushing to standardise and rationalise what Vichy was allowed to keep, and as units were disbanded their aircraft became a resource for Germany to allocate. Passing Bloch fighters to the Royal Romanian Air Force \u2014 an Axis co-belligerent fighting in the east \u2014 was simply an efficient use of captured stock. Aircraft built to defend France ended their service in the markings of a German ally.<\/p>\n<p>A few MB.152s reached the other France \u2014 the Free French forces that fought on from the empire and from Britain \u2014 but the numbers were small, and the type was already obsolescent. For the most part, the MB.152\u2019s post-armistice life was a slow fade under Vichy rather than a fresh combat career. It is a quietly unhappy coda, and an honest history has to include it rather than airbrush the Vichy years out.<\/p>\n<p>As the war turned and Vichy\u2019s forces were disarmed or absorbed, the surviving MB.152s were handed on: to Romania through German arrangement, and in small numbers into Luftwaffe training units. It was an unglamorous, fragmented end for a fighter that, only a couple of years earlier, had been one of the pillars of France\u2019s air defence.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">Reputation<\/p>\n<h3>The Bloch MB.152: tactics, reputation and a fair verdict<\/h3>\n<p>How should the MB.152 be judged? For decades the easy answer was to lump it in with the general story of French collapse in 1940 \u2014 a symbol of an air force that was outdated and overwhelmed. That verdict is too harsh, and it confuses the aircraft with its circumstances.<\/p>\n<p><b>Tactically<\/b>, the MB.152 was a defensive interceptor, and it was flown as one. It could not fight the Bf 109E on the German\u2019s terms, so its pilots used its strengths: firepower, durability, and steadiness on the guns. They intercepted, hit hard, and survived hits. That is a coherent way to fight a faster enemy, and the claim-to-loss record shows it worked more often than not.<\/p>\n<p><b>Strategically<\/b>, the type was a victim of timing and industry. Delivered late, delayed by engine troubles, produced by a disrupted aircraft industry, and burdened with short range, it never reached the front in the strength or readiness it needed. Those are failures of planning and production more than of the airframe.<\/p>\n<p><b>The fair verdict<\/b>: the MB.152 was a tough, well-armed, honest fighter with one crippling limitation (range) and one insurmountable rival (the 109E). It was not France\u2019s best fighter of 1940 \u2014 that was the D.520 \u2014 but it was one of the three the country actually had in numbers, and it did real damage. It deserves to be remembered as a competent defender let down by the war around it, not as a punchline.<\/p>\n<p>The comparison the MB.152 always loses in the popular mind is with the Battle of Britain\u2019s Spitfire and Hurricane. But that is an unfair frame. Those aircraft fought a defensive battle their side had prepared for, with radar, ground control and secure bases behind them, and they are remembered through the lens of victory. The MB.152 fought a defensive battle its side had catastrophically failed to prepare, from crumbling bases, and it is remembered through the lens of defeat. Change the surrounding war, not the aircraft, and the memory flips.<\/p>\n<p>There is a lesson here about how aircraft get their reputations. Hardware is judged by outcomes, and outcomes are dominated by strategy, numbers, training and luck \u2014 not just by the merits of the machine. The MB.152 is a case study in a decent aircraft inheriting the reputation of the disaster it happened to be present for. Pulling the two apart is exactly the job of a fair encyclopedia entry.<\/p>\n<p>Historians have gradually revised the type upward. The old caricature \u2014 an obsolete French fighter swept aside in 1940 \u2014 has given way to a more careful reading that credits the MB.152\u2019s firepower, durability and genuine combat results while being clear-eyed about its range, its performance deficit and its troubled production. That is roughly where this page lands: not a great fighter, not a bad one, but a solid and under-appreciated one, badly served by circumstance.<\/p>\n<p>Perhaps the fairest single sentence is this: the MB.152 did its job better than France did hers. It went up when ordered, it hit hard, it brought many of its pilots home, and it accounted for far more of the enemy than it lost. In a campaign defined by failure, that is a record worth rescuing from the footnotes.<\/p>\n<p>The Marcel Bloch-to-Dassault legacy only sharpens the point: the firm that built this under-appreciated fighter would go on to define modern French air power. The MB.152 was not the end of a dead line, but the modest beginning of a great one.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\">\n<div class=\"wrap\">\n<p class=\"kicker\">Gallery<\/p>\n<h2>The Bloch MB.152 in photographs<\/h2>\n<div class=\"gtrack\">\n<figure><img data-opt-id=587662321  data-opt-src=\"https:\/\/ml5psubhxdln.i.optimole.com\/cb:78--.b845\/w:1536\/h:734\/q:96\/f:best\/https:\/\/migflug.com\/wp-content\/uploads\/2026\/08\/bloch-mb-152-fighter-in-flight-1938.jpg\"  decoding=\"async\" src=\"data:image/svg+xml,%3Csvg%20viewBox%3D%220%200%201536%20734%22%20width%3D%221536%22%20height%3D%22734%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%3E%3Crect%20width%3D%221536%22%20height%3D%22734%22%20fill%3D%22transparent%22%2F%3E%3C%2Fsvg%3E\" alt=\"Bloch MB.152 family fighter in flight, 1938\"><figcaption>A Bloch MB.151 \u2014 the near-identical stablemate of the MB.152 \u2014 in flight, 1938.

Unlike the D.520, no complete, airworthy or widely-recognised intact original is known to survive.<\/p>\n<p>The reasons are simple and grim. The type was <b>used up<\/b> in a lost campaign, then <b>scattered<\/b> across Vichy, Romanian and German hands, and finally <b>scrapped<\/b> as obsolete. Aircraft that end a war as a defeated nation\u2019s cast-offs rarely get preserved.<\/p>\n<p>French national collections \u2014 the Mus\u00e9e de l\u2019Air et de l\u2019Espace at Le Bourget among them \u2014 are associated with surviving Bloch material, which may include components, a partial or reconstructed airframe, or family-related items. Published accounts differ on exactly what exists and its completeness, so any claim of a \u201csurviving MB.152\u201d should be treated with caution and checked against the museum\u2019s own current information.<\/p>\n<p>This uncertainty is itself worth being honest about. Aviation reference works and enthusiast sites sometimes state confidently that \u201cone MB.152 survives\u201d or that \u201cno MB.152 survives,\u201d and both are simplifications of a murkier reality involving components, rebuilds and shifting museum holdings over the decades. Rather than pick a side, this page reports the safe, verifiable position: no complete, original, intact MB.152 is widely and reliably recognised today, and anyone wanting a definitive answer should consult the Mus\u00e9e de l\u2019Air directly.<\/p>\n<p>What is not in doubt is the contrast: where you can stand next to a preserved D.520, the MB.152 has essentially vanished. That absence is a quiet measure of just how completely the events of 1940\u201345 consumed it.<\/p>\n<p>There is a broader pattern here. The aircraft that survive into museums tend to be the winners, the record-breakers, the long-serving types, and the machines of nations that ended the war intact and proud. Fighters that served a defeated power for a few weeks in 1940, were scattered among enemies and allies, and were then scrapped as obsolete were about as unlucky as an airframe can be. The MB.152\u2019s near-total disappearance is not a comment on its quality; it is a comment on its history.<\/p>\n<p>That is part of why a page like this one matters. When almost no physical examples remain, the written and photographic record has to carry the memory. The MB.152 deserves to be remembered accurately \u2014 as a tough, well-armed, honest interceptor with a crippling range limitation and a great corporate legacy \u2014 rather than lazily filed away as just another casualty of 1940.<\/p>\n<p>The contrast with its siblings is instructive. Around a handful of Dewoitine D.520s survive, including at least one that was returned to flight; several Morane-Saulnier MS.406-family aircraft (including the Swiss D-3801 derivative) also endure. The MB.152 falls off the bottom of that list. Why? Partly chance, partly the type\u2019s scattering across Vichy, Romanian and German hands, and partly the simple fact that obsolete fighters of a defeated nation were near the top of every scrap queue.<\/p>\n<p>If you want to get close to the MB.152 today, the Mus\u00e9e de l\u2019Air et de l\u2019Espace at Le Bourget is the place to start any enquiry, both for its holdings of French 1940 aviation and as the authority on what Bloch material actually survives. Beyond that, the type is best encountered through archival photographs, the technical literature, and the excellent scale-model subjects that keep its distinctive shape alive.<\/p>\n<p>For the modern enthusiast, the MB.152 lives mainly in photographs of its near-twin the MB.151, in technical drawings, in scale models, and in the written record of the men who flew it.<\/p>\n<\/div>\n<\/div>\n<div class=\"sec\" id=\"faq\">\n<div class=\"wrap\">\n<p class=\"kicker\">Q&amp;A<\/p>\n<h2>Bloch MB.152: your questions answered<\/h2>\n<div class=\"faq\">\n<details class=\"qa\" open=\"\">\n<summary>Can I fly in a Bloch MB.152?<\/summary>\n<div class=\"a\">\n<p>No. No complete, airworthy Bloch MB.152 is known to exist \u2014 the type all but vanished after 1945, and at most a partial or reconstructed airframe and components survive in museum collections. There is no bookable flight in an MB.152 anywhere, and MiGFlug does not offer one.<\/p>\n<p>The good news is that flying in a genuine military aircraft is not a fantasy. MiGFlug puts civilians in the cockpit of real, flying fighter and trainer jets \u2014 from Cold War classics to supersonic interceptors. If the idea of the MB.152 stirs something in you, that same thrill is very much available today: see <a href=\"https:\/\/migflug.com\/flights-prices\/\">migflug.com\/flights-prices<\/a>.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>Was the Bloch MB.152 a good fighter?<\/summary>\n<div class=\"a\">\n<p>It was a mixed but genuinely capable one. Its strengths were real: heavy armament (two 20 mm cannon plus two machine guns), a tough airframe that absorbed damage, and stability that made it a good gun platform. Its weaknesses were also real: short range (~600 km), speed and agility inferior to the Bf 109E, and a development plagued by engine and production delays. It was not France\u2019s best 1940 fighter \u2014 that was the Dewoitine D.520 \u2014 but it was a competent interceptor that fought well.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>How does the MB.152 compare to the Dewoitine D.520 and MS.406?<\/summary>\n<div class=\"a\">\n<p>These were the three fighters the Arm\u00e9e de l\u2019Air had in numbers in 1940. The D.520 was clearly the best \u2014 faster, more agile, longer-ranged \u2014 but reached squadrons in tiny numbers by May 1940. The MS.406 was the most numerous but the weakest performer. The MB.152 sat in between: faster and better-armed than the MS.406, but slower and shorter-legged than the D.520.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>Why did the MB.152 have such a bad reputation?<\/summary>\n<div class=\"a\">\n<p>Mostly by association with France\u2019s defeat, and because of its genuine flaws \u2014 short range, delayed and often unready deliveries, and inferiority to the Bf 109E. But its actual air combat record (roughly 188 claims for about 86 losses) is far better than its reputation suggests. It was an unfinished fighter fighting a battle already being lost on the ground, not a fundamentally bad aircraft.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>What engine and weapons did the MB.152 use?<\/summary>\n<div class=\"a\">\n<p>It was powered by a Gnome-Rh\u00f4ne 14N two-row radial of roughly 1,000\u20131,100 hp (most MB.152s used the ~1,050 hp 14N-25). The standard combat armament was two 20 mm Hispano-Suiza HS.404 cannon plus two 7.5 mm MAC 1934 machine guns in the wings. The related MB.151 was usually armed with four machine guns instead.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>How many Bloch MB.152s were built?<\/summary>\n<div class=\"a\">\n<p>A commonly cited figure is 482 MB.152s, with the wider MB.151\/152\/155 family reaching somewhere above 600 aircraft. Figures vary between sources and should be treated as approximate. By the outbreak of war in September 1939 around 120 Bloch fighters had been delivered, but many were not yet combat-ready.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>Who flew the MB.152 besides France?<\/summary>\n<div class=\"a\">\n<p>After France\u2019s main use in 1940, the MB.152 served the Vichy French air force (six groups) and, in small numbers, the Free French. Greece received nine of 25 ordered MB.151s before France fell and used them against Italy. Later, the Germans passed some Bloch fighters to the Royal Romanian Air Force, and a few ended up in Luftwaffe hands as trainers.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>What is the connection between Bloch and Dassault?<\/summary>\n<div class=\"a\">\n<p>They are the same company. Marcel Bloch designed the MB.150 family, survived deportation and the Buchenwald concentration camp during the war, and afterwards rebuilt his firm under the name Dassault (from his brother\u2019s Resistance codename). The MB.152 is therefore a direct ancestor of the Ouragan, Myst\u00e8re, Mirage and Rafale.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>Are there any surviving Bloch MB.152s?<\/summary>\n<div class=\"a\">\n<p>No complete, original MB.152 is widely recognised as preserved intact. French collections such as the Mus\u00e9e de l\u2019Air et de l\u2019Espace are associated with surviving Bloch components or partial material, but published accounts differ on exactly what exists. Treat any claim of a fully intact surviving MB.152 with caution.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>How fast was the Bloch MB.152 and how far could it fly?<\/summary>\n<div class=\"a\">\n<p>Its maximum speed was around 509 km\/h (316 mph), with sources ranging roughly 500\u2013515 km\/h depending on variant. Its range was only about 600 km (370 mi) \u2014 the type\u2019s defining weakness. Service ceiling was around 10,000 m, and it climbed to 2,000 m in a little over three minutes. The short range is the figure most worth remembering.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>Did the Bloch MB.152 fight the Italians as well as the Germans?<\/summary>\n<div class=\"a\">\n<p>Yes. When Italy entered the war on 10 June 1940, MB.152 units in southern France engaged the Regia Aeronautica during the brief Italian campaign before the armistice. Against older Italian biplanes and lightly-armed monoplanes, the MB.152\u2019s two 20 mm cannon and tough airframe were particularly effective. Greek-operated MB.151s also fought the Italians (and later the Germans) in the Balkans.<\/p>\n<\/div>\n<\/details>\n<details class=\"qa\">\n<summary>Why is the MB.152 so much rarer today than the D.520?<\/summary>\n<div class=\"a\">\n<p>It was used up in a lost campaign, then scattered across Vichy, Romanian and German hands, and finally scrapped as an obsolete fighter of a defeated power \u2014 the worst possible combination for long-term survival. Where several D.520s and MS.406-family aircraft endure, no intact original MB.152 is widely recognised today. Its rarity is a direct consequence of how completely the 1940\u201345 years consumed it.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n<p> <script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Can I fly in a Bloch MB.152?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. No complete, airworthy Bloch MB.152 is known to exist and MiGFlug does not offer one.
