The swing-wing that armed the Soviet front line

What makes the MiG-23 special

Full MiG-23 specifications

Baseline note: the figures below describe the Mikoyan-Gurevich MiG-23MLD (factory model 23-18, NATO reporting name Flogger-K) — the last and best single-seat fighter Flogger, powered by the Khachaturov R-35-300 turbojet and carrying the Sapfir-23MLA-II (N008 Ametist) radar. That mark is the right baseline because it is the only one in which the aeroplane finally did what it had been sold as doing since 1969: a strengthened wing pivot, a fourth sweep detent, an angle-of-attack limiter borrowed from the MiG-29 and a radar that could actually look down over broken ground. Deltas for the MiG-23M/MF (Flogger-B), the lightened MiG-23ML (Flogger-G), the ground-attack MiG-23BN (Flogger-H) and the deliberately crippled export MiG-23MS (Flogger-E) are given in grey. One boundary first. The MiG-27 is a separate aircraft with its own page. It shares this aeroplane’s wing and fuselage cross-section and almost nothing else that matters: fixed intakes instead of variable ramps, a short two-position nozzle instead of a fully modulating one, a sloped radarless nose instead of a Sapfir radome, cockpit armour, and a six-barrel GSh-6-30 cannon no MiG-23 ever carried. The MiG-23B and MiG-23BN are attack MiG-23s and belong here; the MiG-27 does not. NATO drew the same line — Flogger-F and -H are MiG-23s, Flogger-D, -J and -J2 are MiG-27s. Four cautions about the numbers. First, sweep. The MiG-23 is universally described as having three wing positions, and the cockpit placards, the manuals and the pilot’s selector detents all say 16°, 45° and 72°. Both halves of that are approximations. The true leading-edge angles on the production Edition 2 and Edition 3 wings are 18°40′, 47°40′ and 74°40′, retained under the old labels for convenience; and the wing is in fact continuously variable anywhere between the stops, with about 30° used for ferry flights. The three positions are detents, not the mechanism’s limits. Second, height. Brassey’s gives 4.82 m for the MLD, but that figure comes from a MiG-23MF drawing; the redesigned ML/MLD main undercarriage changed the aircraft’s sit on the ground and Russian sources give 5.00 m. Third, maximum take-off weight. The English-language specification tables commonly print 17,800 kg for the MLD; that is the MiG-23ML figure. Russian sources and the airwar.ru data give 20,100 kg for the MLD. Fourth, ceiling and climb: Brassey’s gives 18,500 m and 230 m/s, Russian service data 17,700 m and 215 m/s with two R-23s aboard. Where the two traditions disagree, both are shown. Why the wing is swept by hand. The F-111 and the F-14 both schedule sweep automatically, the Tomcat’s central air data computer moving the wings continuously against Mach number so the pilot never thinks about them. The MiG-23 does not. Its wings are driven by an SPK-1 two-channel hydraulic motor turning IP-23 ball-screw jacks, and the pilot moves them with a small lever on the left console beside the throttle, into one of three detents. There is a gauge showing where the wings are and what the Mach limit is for that position; there is nothing telling the pilot which position he ought to be using. Soviet accounts do not spell out the decision, so the reasoning has to be inferred from what the requirement actually was, and it is not hard to see. The MiG-23 was ordered as a replacement for the MiG-21 that could operate from short, rough and bomb-damaged strips and still dash at Mach 2 — variable geometry was bought for field performance and for a supersonic intercept profile that was known before take-off, not for manoeuvring. A GCI-directed point-defence interceptor flies a briefed profile: spread for take-off, mid-sweep for the transit, fully swept for the run-in. An automatic scheduler would have added a computer, sensors and failure modes to an aircraft whose wing box was already a welded steel component that kept cracking, and would have bought nothing the mission profile needed. The same logic produced manual sweep on the Su-17, the Su-24 and the Tu-22M. It was the correct choice for the aeroplane the Soviets thought they were buying, and the wrong one for the dogfight the MiG-23 kept being dragged into, where a pilot at 6 g had one more thing to do with his left hand at exactly the moment he could least afford it. The reputation, stated plainly. The MiG-23 was heavy, unforgiving and disliked. It lost turning fights to the MiG-21 it replaced, which its own pilots found demoralising. American exploitation under HAVE PAD and the Constant Peg programme found that it turned about as well as an unslatted F-4E and that anything newer could out-turn it easily, that it went unstable and departed controlled flight near high angle of attack, that it was unstable in yaw through Mach 1 and again near Mach 2, that its narrow-track undercarriage slid on wet surfaces, and that sitting low it ingested debris. The control column carried a "knuckle rapper" that struck the pilot’s hand as 17° angle of attack approached. Rearward visibility was poor: the KM-1 seat wrapped around the pilot’s head, so checking six meant leaning forward and using a periscope let into the canopy rail. The 4477th Test and Evaluation Squadron nicknamed it the "Looping Hog". Accident rates bear the complaints out — about 12.5 losses per 100,000 flying hours in Soviet service, 24.3 in Hungarian, 20.4 in East German, and roughly half of India’s 70 aircraft written off over 28 years. And yet the same testing concluded that the MiG-23 was a serious threat. It out-accelerated every American fighter below 10,000 ft and through the sound barrier, it was small and hard to see, and with a radar, an infrared search and track, a datalink and the R-23 it could shoot at something it had never laid eyes on. Constant Peg used it to simulate two separate threats: a low-level runner NATO strike aircraft could not escape, and a MiG-25-style high fast flyer coming for the tankers and the E-3s. East German crews, listened to on GCI tapes, knew precisely what they had and planned to overwhelm from many directions at once. It was a bad dogfighter and a good interceptor, and the two judgements are not in conflict. The combat record. It is one of the worst of any major postwar fighter, and the reasons are only partly the aeroplane’s. Syria took the type into action first, on 19 April 1974, when Captain al-Masry claimed two Israeli F-4Es with a MiG-23MS before being shot down by his own side’s surface-to-air missile battery. Over Lebanon in June 1982, against F-15s and F-16s covered by superb electronic warfare and airborne control, Syrian losses were catastrophic: the Russian historian Vladimir Ilyin counts six MiG-23MFs, four MiG-23MSs and fourteen MiG-23BNs lost that month, with 11 to 13 fighter variants lost in air combat between 1982 and 1985; Israel acknowledges losing to Syrian MiG-23s only a BQM-34 Firebee drone, downed by a MiG-23MF on 6 June 1982. Iraq flew Floggers throughout the war with Iran and had a slightly better time of it, claiming about twenty aerial victories of which seven survive cross-checking against Iranian records — including two F-14 Tomcats — while official Iraqi documents admit 38 MiG-23BNs and five interceptors lost, a figure the same documents’ pilot-casualty lists show to be understated. Iraq had 127 MiG-23s on 17 January 1991 and lost 43 of them to all causes in six weeks, eight of those to USAF F-15s. Libya lost two MiG-23s to US Navy F-14As of VF-32 north of Tobruk on 4 January 1989, after three AIM-7 Sparrows missed or failed and a fourth and then an AIM-9 connected; both Libyan pilots ejected into the sea. Soviet MiG-23s in Afghanistan escorted where the MiG-21 lacked the legs, flew about fifteen per cent of their sorties as escort or combat air patrol, and killed two Iranian AH-1J Cobras with R-24Rs in September 1988. Cuban MiG-23MLs over Angola damaged a South African Mirage F1CZ on 27 September 1987 badly enough that its pilot, Captain Arthur Piercy, was paralysed by a ground-level ejection when the aircraft ran off the runway; Cuba claims six victories in total, one confirmed destroyed. UNITA shot MiG-23s down with American Stinger missiles, and South African troops downed one with a 20 mm Ystervark gun over the Calueque dam. Ethiopian MiG-23BNs bombed Eritrean targets, and three were shot down by Eritrean MiG-29s. And the flight nobody was on. On 4 July 1989 a MiG-23M of the 871st Fighter Aviation Regiment took off from Bagicz, near Kołobrzeg in Poland. Forty-one seconds into the climb Colonel Nikolai Skuridin heard a bang from the intake and saw the engine wind down; he reported the failure, was cleared to abandon the aircraft and ejected at around 150 m. Six seconds later the engine recovered. With the wings at minimum sweep and the attitude-hold system doing what it was built to do, the empty MiG-23 climbed to roughly 12,000 m and flew west at about 740 km/h across Poland and East Germany. A pair of USAF F-15s from the 32nd Tactical Fighter Squadron intercepted it over West Germany, found the cockpit empty, and escorted it over the Netherlands and into Belgium without being permitted to shoot it down over populated ground. When the fuel ran out the aircraft glided into a house at 273 Doornikserijksweg in Bellegem, a village belonging to Kortrijk, about 900 km from where its pilot had left it, and killed Wim Delaere, a computer science student of eighteen or nineteen — sources differ — asleep inside. The Soviet Union paid Belgium 685,000 US dollars. The engine fault was never established. It is the most famous thing the MiG-23 ever did, and it did it with nobody aboard.

Armament & payload

The MiG-23 gave the Soviet Union a missile its pilots could shoot before they could see

The MiG-21 was a gunfighter with a pair of short-range infrared rounds. The MiG-23 was built around the R-23 (NATO AA-7 Apex), a 222 kg medium-range weapon in semi-active radar and infrared forms, and around the Sapfir radar that could illuminate for it. That combination — a look-down radar, a real beyond-visual-range missile, a datalink taking steering commands from a ground controller and a head-up display — is the whole point of the aeroplane, and in 1974 nothing else in Soviet front-line service had it.

The rounds were not long-legged by later standards. The R-23R reached about 25 km head-on at height and only 14 km down low; the improved R-24 of 1981 stretched that to roughly 35 km with a 35 kg warhead and lock-on-after-launch. What mattered was that a MiG-23 pilot, cued by ground control onto a target he had never seen, could shoot first. Close in he had the R-60, a 44 kg infrared dart carried four or six at a time on twin rails, and a twin-barrel GSh-23L with 200 rounds in a ventral trough. Ground attack was an afterthought on the fighter marks: iron bombs, rocket pods, the radio-command Kh-23, and a single tactical nuclear bomb on a centreline adaptor.

Store carriage is the aeroplane’s one genuinely awkward feature. Two pylons sit under the fixed wing gloves and two under the fuselage; a further pair on the movable outer panels can take drop tanks only, cannot be swung, and must be jettisoned before the wings are swept. That is why sources variously quote five or six hardpoints for the same aircraft, and why a MiG-23 going supersonic arrives with less fuel than its tankage suggests. Clearances differed sharply by mark and customer: the MiG-23MS could fire nothing better than the R-3S and later the R-13M, the MiG-23MF sold outside the Warsaw Pact had degraded radar and no electronic counter-countermeasures, the R-24 was cleared only from 1981 on MLA and MLD airframes, and nuclear carriage was Soviet-only.

Sourcing caveat: weapon fits are drawn from Yefim Gordon and Alexander Mladenov’s monographs, the English and Russian Wikipedia specification tables and airwar.ru, checked against one another; they disagree at the margins, particularly over hardpoint counts and over whether the outer wing pylons should be counted at all. Missile performance figures are nominal manufacturer envelopes, not what anybody achieved in combat: Syrian, Iraqi and Libyan MiG-23 crews fired R-23s and R-24s in numbers and hit very little with them, for reasons that had at least as much to do with training, maintenance and Israeli and American electronic countermeasures as with the rounds themselves.

Variants

Mikoyan built roughly 5,000 Floggers, and spent fifteen years fixing the first one

The MiG-23 is the rare combat aircraft whose development history is essentially a repair log. The 1969 MiG-23S was dangerous at high angle of attack, prone to spinning, and cracked between the centre fuselage and the wings; the Edition 1971 wing added area and a dogtooth but deleted the leading-edge slats and made the handling worse; the MiG-23M put the slats back and gave the type a usable radar, then had to be restricted to 5 g until 1977 because the welded steel No. 2 fuel tank — which is also the wing carry-through box — kept developing hairline cracks and leaking. Only with the MiG-23ML of 1975, which threw away 1,250 kg by deleting a fuel tank and a dorsal fin extension and strengthened the wing pivot, did the aeroplane become something a squadron could fly hard.

The export policy is worth stating plainly because it shaped the combat record. Moscow sold three grades of Flogger: near-Soviet-standard aircraft to the Warsaw Pact, a degraded version of the same mark to trusted third-world customers, and to everyone else the MiG-23MS — a MiG-23 airframe with MiG-21 avionics, a stubby export radar, no infrared search and track, and no beyond-visual-range missile at all. Syria, Iraq, Egypt and Libya all received MS aircraft first. When Syrian MiG-23s met Israeli F-15s and F-16s over Lebanon in June 1982, a large fraction of them were aircraft that could not shoot at anything they could not see, flown by crews who had been given no technical documentation worth the name.

Production ran from 1968 to 1985 at two plants. Znamya Truda in Moscow built 4,256 single-seaters; Irkutsk built 1,008 MiG-23UB two-seaters, giving a Russian total of about 5,264, against the 5,047 usually printed in English sources. Either way the MiG-23 is one of the most numerous supersonic aircraft ever built, and it was never licence-produced abroad — India assembled the MiG-27M as the Bahadur, but that is a different aeroplane on a different page.

MiG-23S (Flogger-A, 1969–71, about 60 built)

First production mark, fitted with the MiG-21’s RP-22SM radar because the Sapfir-23 was late; withdrawn after brief front-line service when testing exposed spin behaviour, cracking and fatal accidents.

MiG-23 Edition 1971 (Flogger-A, 1971, about 80 built)

First with the Sapfir-23L radar, TP-23 infrared search and track and the R-23R missile; new Edition 2 wing with 20 per cent more area and a dogtooth but no slats, which made an already awkward aeroplane worse. Relegated to training in 1978.

MiG-23M (Flogger-B, 1972–78, about 1,300 built)

The definitive first generation and the most-produced fighter mark: Sapfir-23D with genuine look-down/shoot-down, R-23 and R-60, the R-29-300 engine, slats restored on the Edition 3 wing, and plumbed wing pylons for 800 L tanks.

MiG-23MF (Flogger-B, export, 1978–83)

Export MiG-23M in two grades: a near-identical Warsaw Pact version, and a third-world version with the radar redesignated Sapfir-23E, no electronic counter-countermeasures, weaker radios and, until 1981, R-13M instead of R-60.

MiG-23MS (Flogger-E, 1973–78; 54 to Syria, 54 to Libya, 18 to Iraq, 8 to Egypt)

The deliberate downgrade: MiG-23M airframe and engine with the MiG-21S weapons system, a short-nosed export RP-22SM radar, no infrared search and track and no radar-guided missile. Its radar was notoriously easy to jam, and Israeli crews did exactly that.

MiG-23ML / MiG-23MLA (Flogger-G, 1976–83, more than 1,100 built)

The redesign that made the type work: 1,250 kg lighter, cleaner aerodynamically, stronger wing pivot, R-35-300 engine, 8.5 g cleared, Sapfir-23ML and then the better MLA radar, and from 1981 the R-24. Mikoyan assessed it as about 20 per cent more combat-effective than the MiG-23M.

MiG-23P (Flogger-G, 1978–81, about 500 built, never exported)

Specialised air-defence interceptor for the PVO with the Sapfir-23P radar and a digital autopilot that let ground controllers fly the aircraft to the firing point; the pilot handled only throttle and weapons. The last MiG-23 in Russian service, retired on 1 May 1998.

MiG-23MLD (Flogger-K, 1982–85; 560 Soviet conversions, 66 new-build for export)

The final fighter: vortex generators on the pitot boom and wing roots, a MiG-29 stick-stop limiter, a fourth 33° sweep detent, the Sapfir-23MLA-II radar and much better countermeasures. No Soviet MLD was new-built — all were reworked ML/MLA airframes — while Bulgaria took 16 and Syria 50 new-build examples that lacked the Soviet aerodynamic refinements.

MiG-23B / MiG-23BN (Flogger-F and -H, 1971–85, 624 built)

The attack MiG-23: flat tapered nose with the PrNK Sokol-23 sight system and laser rangefinder instead of radar, armoured windscreen, raised seat, inert-gas fuel system, 3,000 kg of stores. The B used the Lyulka AL-21F and was capped at 24 aircraft because Sukhoi needed the engine; the BN reverted to the R-29B-300 and became the most exported Flogger of all.

MiG-23UB / MiG-23UM (Flogger-C, 1970–85, 1,008 built at Irkutsk)

Two-seat trainer with a raised rear cockpit and, on most airframes, ballast under a metal fairing where the radar should be. Used in Afghanistan for strike, reconnaissance and as an improvised airborne controller — the back-seater directing a strike package, a practice the crews called "I am my own AWACS". 251 were reworked as MiG-23UMs from 1984.

Closing caveat: the Soviet Union stopped short of the upgrades that might have kept the type competitive. The MiG-23-98 package offered in the late 1990s — new radar, helmet-mounted sight, R-27, R-73 and R-77 — was priced at about a million US dollars per aircraft and found no buyer beyond a limited Angolan proposal. Retirement was fast where money existed: Hungary 1996, Czech Republic and Russia 1998, Poland 1999, Romania 2000, Bulgaria 2002–04, India 2009. The MiG-27 is a separate aircraft with a separate page and its own retirement history, and should not be counted in any MiG-23 total. Two-seat MiG-23UBs survive on the Western warbird circuit in small numbers; one crashed at an airshow at Willow Run, Michigan, on 13 August 2023 after both crew ejected, damaging cars but injuring nobody.

Operators today

North Korea flies more than half of the world’s surviving MiG-23s

The Flogger has almost finished leaving service. Russia retired the last MiG-23P on 1 May 1998; the European operators were gone by 2004 and India by 2009. What is left is a short list of air forces for which a supersonic aircraft of any kind is a strategic asset, and where the airframes have been kept alive by cannibalisation, Belarusian and Ukrainian spares, and in Sudan’s case by hauling jets out of twenty years of storage and rebuilding them locally.

Three names that appear on most published lists are deliberately absent here. Syria was the largest MiG-23 operator in the world as recently as December 2024, with 87 on strength; the Assad government fell that month, Israel destroyed at least 60 MiG-23s in Operation Bashan Arrow, and FlightGlobal removed the entire Syrian inventory from its 2026 directory. There is no honest number to print. Cuba still shows 24 airframes on paper, but the same directory marks all of them non-operational, and Cuban sources have described only three as flyable as long ago as 2011. Zimbabwe, whose MiG-23s were a gift from Gaddafi, listed three in December 2024 and retired the type in 2025.

These are estimates, current to FlightGlobal’s World Air Forces 2026 directory, published December 2025 and reflecting inventories at the end of 2025; checked 3 September 2026. North Korea’s 56 are MF, MS and ML variants concentrated at Pukchang and are the most modern fighters it has after its small MiG-29 force; Angola’s 22 are MiG-23ML and UB, some supplied second-hand by Belarus; Ethiopia’s 9 are MiG-23BN attack aircraft, one of which was reportedly lost over Tigray in November 2020; Sudan’s 4 are MiG-23MS with one two-seater, refurbished from storage from 2010 onwards with Russian, Belarusian and Ethiopian help. Libya’s figure is the least reliable on the page: the aircraft are split between rival governments, the IISS Military Balance 2024 counted two MiG-23BN with the Government of National Unity and two MiG-23ML with the Libyan National Army, and individual airframes have been rebuilt from the wings of two or three wrecks. Many airframes counted on paper anywhere on this list are stored, cannibalised or unflyable.

Where the Flogger flew

One of the most combat-tested Soviet jets

The MiG-23 saw more combat than almost any other Soviet-era fighter — but its air-to-air record is fiercely contested, and every kill and loss total below should be read as a claim, not a settled score. What is beyond dispute is the sheer breadth of its fighting career, from the Bekaa Valley to the Persian Gulf, Angola, Libya and Syria.
