Near Utti, seven of them met one Finnish lieutenant in a Dutch fighter with fixed landing gear and four rifle-calibre machine guns.<\/p>\r\n\r\n<p>Jorma Sarvanto shot down six of them in about four minutes. A seventh fell to his squadron mate Per-Erik Sovelius before it could reach home. Newspapers across the West called it a world record, and the fighter that made it possible became a national legend: the <a href=\"https:\/\/migflug.com\/aircraft\/fokker-d-xxi\/\">Fokker D.XXI<\/a>.<\/p>\r\n\r\n\r\n<div style=\"background:#f4f6f9;border:1px solid #e2e7ee;padding:18px 22px;margin:22px 0 26px\"><p style=\"margin:0 0 8px;font-weight:700;color:#0d1117\">Quick Facts<\/p><ul style=\"margin:0;padding-left:18px\"><li style=\"margin:4px 0\"><strong>Aircraft:<\/strong> Fokker D.XXI, single-seat fighter (Netherlands)<\/li><li style=\"margin:4px 0\"><strong>First flight:<\/strong> 27 March 1936, Eindhoven<\/li><li style=\"margin:4px 0\"><strong>Finnish service:<\/strong> Seven bought from Fokker in 1937; more built under licence at Tampere; in service until 1949<\/li><li style=\"margin:4px 0\"><strong>Engine:<\/strong> Bristol Mercury VIII radial, 830 hp (Winter War aircraft)<\/li><li style=\"margin:4px 0\"><strong>Armament:<\/strong> Four 7.92 mm machine guns<\/li><li style=\"margin:4px 0\"><strong>Top speed:<\/strong> About 460 km\/h (286 mph)<\/li><li style=\"margin:4px 0\"><strong>Winter War:<\/strong> About 40 in service; 12 lost, six in accidents<\/li><li style=\"margin:4px 0\"><strong>Record day:<\/strong> 6 January 1940: Jorma Sarvanto shoots down six DB-3 bombers in about four minutes<\/li><\/ul><\/div>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">A cheap fighter from Amsterdam<\/h2>\r\n\r\n<p>Fokker designed the D.XXI in the mid-1930s as an inexpensive, rugged and compact fighter, first for the Dutch Army Aviation Group. The prototype flew at Eindhoven on 27 March 1936. It was a low-wing monoplane with an enclosed cockpit, a Bristol Mercury radial engine and a fixed, spatted undercarriage that already looked a little old-fashioned when it rolled out.<\/p>\r\n\r\n<p>Finland liked it anyway. In 1937 the government ordered seven from Fokker and bought a licence, and the State Aircraft Factory at Tampere began building more. When the Soviet Union invaded on 30 November 1939, the <a href=\"https:\/\/migflug.com\/air-forces\/finnish-air-force\/\">Finnish Air Force<\/a> had about 40 Mercury-engined D.XXIs, the backbone of its fighter force.<\/p>\r\n\r\n<p>The Dutch had their own war to fight. When Germany invaded the Netherlands on 10 May 1940, 28 Dutch D.XXIs were serviceable, and on the first day six of them escorted Fokker T.V bombers against the Meuse bridges and tangled with <a href=\"https:\/\/migflug.com\/aircraft\/messerschmitt-bf-109\/\">Bf 109s<\/a>. Denmark had built ten under licence before the German invasion in April 1940. In both countries the fight was brief. Only in Finland did the Fokker get a long war.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/11\/fokker-d-xxi-mechanics-winter-tiiksjarvi-1941.jpg\" alt=\"Finnish mechanics work on the Bristol Mercury engine of a Fokker D.XXI fighter at a snowy forest airfield\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">Mechanics prepare a Finnish Fokker D.XXI at Tiiksj&auml;rvi in 26 degrees of frost, November 1941. The rugged fixed-gear fighter suited Finland&rsquo;s winter conditions. Photo: SA-kuva \/ public domain<\/figcaption><\/figure>\r\n\r\n\r\n<p>On paper the odds were absurd. Air Force Magazine historian Richard Hallion counts 2,318 Soviet aircraft against 114 Finnish ones. The Fokker had a top speed of around 460 km\/h (286 mph) and only four 7.92 mm machine guns. But its rugged radial engine and fixed undercarriage suited Finnish conditions, the gear took to skis and rough snowy strips, and its pilots were exceptionally well trained.<\/p>\r\n\r\n\r\n<div style=\"background:#f8f9fa;border-left:4px solid #1565c0;padding:20px 22px;margin:18px 0 24px;font-size:16px;line-height:1.7\"><div><em>&ldquo;Our esprit de corps was high despite the fact that we would be up against heavy odds.

Its leaders had drilled the pilots hard in gunnery and tactics, and had taught them to avoid turning fights with nimble Soviet biplanes. Their target was the bombers. The D.XXI scored its first victory on 1 December 1939, the second day of the war, shooting down a <a href=\"https:\/\/migflug.com\/aircraft\/tupolev-sb\/\">Tupolev SB<\/a>.<\/p>\r\n\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0 8px\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/pWnkg8V3IGY\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div>\r\n\r\n<p style=\"font-size:13px;color:#777;text-align:center;font-style:italic;margin:0 0 24px\">Ed Nash&rsquo;s Military Matters on the Fokker D.XXI, the Dutch fighter that served Finland far longer than anyone expected.<\/p>\r\n\r\n<p>The pilots had a rhythm by Christmas. According to Hallion, LeLv 24 shot down 12 bombers on 19 December and ended 1939 having destroyed 54 aircraft for the loss of one Fokker. Among the young pilots was Ilmari Juutilainen, who would become Finland&rsquo;s top ace later in the Second World War.<\/p>\r\n\r\n<h2 style=\"padding-top:22px\">Six bombers in four minutes<\/h2>\r\n\r\n<p>Sarvanto was 27 that winter. Born in Turku, he had graduated top of his military academy class in 1937 and moved to fighters at his own request. In LeLv 24&rsquo;s firing tests he averaged a 92 per cent hit rate. His first two victories came on 23 December 1939.<\/p>\r\n\r\n<p>On 6 January, Finnish signals intelligence warned that a raid was coming. Seventeen DB-3s flew in from Estonia. Near Utti, Sovelius met the second wave first and shot one bomber down. Sarvanto attacked the remaining seven on his own and brought down six of them in about four minutes. Sovelius caught the last one as it crossed the coast.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/11\/jorma-sarvanto-lelv-24-1941.jpg\" alt=\"Finnish fighter ace Lieutenant Jorma Sarvanto climbing out of a fighter cockpit at a forest airfield in 1941\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">Lieutenant Jorma Sarvanto of LeLv 24 at Sel&auml;np&auml;&auml; airfield in June 1941, after the Winter War in which he became Finland&rsquo;s top ace.

Hallion records 34 Soviet aircraft shot down by Finnish Fokkers in January 1940. But Soviet fighter escorts grew stronger, the pilots flew up to eight sorties a day, and fatigue caused accidents. By the end of January, LeLv 24 had only 28 serviceable Fokkers left.<\/p>\r\n\r\n<p>The worst day came on 29 February, when a large force of Polikarpov fighters surprised Fokkers and <a href=\"https:\/\/migflug.com\/aircraft\/gloster-gladiator\/\">Gladiators<\/a> over Immola and shot down seven Finnish aircraft. Two weeks later, on 13 March 1940, the Winter War ended with Finland ceding territory but keeping its independence.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/11\/fokker-d-xxi-formation-tiiksjarvi-1942.jpg\" alt=\"Nine Finnish Fokker D.XXI fighters taking off from a snowy airfield at Tiiksjarvi in 1942\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">Nine Finnish Fokker D.XXIs set off on a ground-attack sortie from Tiiksj&auml;rvi in May 1942.
