Mikoyan MiG-23 — Fighter aircraft (M series)
Open in interactive gallery →See aircraft like this on the live radar →

The Mikoyan MiG-23 (NATO reporting name Flogger) was the Soviet Union's intended successor to the lightweight MiG-21 Fishbed — a single-engined, supersonic, variable-sweep-wing fighter that addressed the Fishbed's principal limitations of short range, light payload, and poor radar by adopting a swing-wing planform, a much larger fuselage, and the powerful Sapfir-23 pulse-Doppler radar. First flown in 1967 and entering Soviet Air Force service in 1970, the MiG-23 became the most numerous Warsaw Pact fighter of the late Cold War and the world's first widely deployed beyond-visual-range Soviet fighter.

The aircraft's defining feature is its three-position variable-geometry wing, sweeping between 16, 45, and 72 degrees to optimise lift at landing speeds, manoeuvre at combat speeds, and drag at supersonic dash. The wing is bolted to the fuselage at a single pivot pin per side — a relatively simple mechanism compared with the more complex F-14 Tomcat or F-111 implementations — at the cost of higher fatigue loading and, ultimately, several catastrophic in-service failures. The MiG-23 mounted a single Khachaturov R-29 (later R-35) afterburning turbojet producing roughly 28,700 lbf with afterburner; combined with a maximum take-off weight of around 39,000 lb, this gave excellent thrust-to-weight performance, supersonic climb, and a 60,000 ft service ceiling, with internal fuel range of 1,181 miles.

Unlike the MiG-21, the MiG-23 was equipped from the start for beyond-visual-range engagement: the Sapfir-23 radar offered look-up search to 85 km, and the aircraft was the first Soviet fighter to carry the semi-active radar-homing R-23/R-24 (AA-7 Apex) missile alongside the IR-guided R-60 (AA-8 Aphid). A dedicated ground-attack derivative — the MiG-27 Flogger-D/J — replaced the radar with a fixed nose-mounted laser rangefinder and added a heavy 30mm GSh-6-30 cannon for close air support. The MiG-23 saw extensive combat in Soviet hands over Afghanistan and Lebanon, and in export service over the Iran-Iraq war, the 1982 Bekaa Valley air battles, the 1991 Gulf War, the 2011 Libyan civil war, and the ongoing Syrian civil war from 2011.

The aircraft developed a reputation for unforgiving handling — pitch-up at high angle of attack, tendency to depart controlled flight if mishandled, and demanding instrument-flight discipline — that contributed to high accident rates in less-experienced air forces. Combat performance against well-flown Western fighters was disappointing: Israeli F-15s and F-16s downed at least 20 Syrian MiG-23s in 1982 with no losses, and U.S. and coalition pilots in 1991 dispatched eight Iraqi MiG-23s without loss. Total production reached approximately 5,047 MiG-23 and 1,075 MiG-27 airframes between 1967 and 1985. Russia retired the type in 1996, but small numbers remain in service with North Korea, Cuba, Syria, Libya, and Sudan as of 2026, with several others in storage as potential reactivation reserves.

For Kids — a shorter, friendlier version

The MiG-23 is a jet fighter made in the Soviet Union. Its NATO nickname was "Flogger." It first flew in 1967 and joined the Soviet Air Force in 1970. It was built to be better than the older MiG-21 fighter.

One of the coolest things about the MiG-23 is its wings. The wings can swing forward or backward while the plane is flying. Pilots could choose three different wing positions. This helped the plane land safely, turn quickly, or zoom at high speed.

The MiG-23 was faster than most cars you will ever see — it could fly faster than the speed of sound! It had a big, powerful engine with an afterburner. An afterburner gives the engine an extra boost of speed, like a turbo button.

The MiG-23 also carried a strong radar system. This radar let pilots spot enemy planes far away. It was the first Soviet fighter used widely with missiles that could hit targets the pilot could not even see yet.

The MiG-23 became one of the most common fighters in the Warsaw Pact, which was a group of countries led by the Soviet Union. A version called the MiG-27 was also made for attacking targets on the ground. Some MiG-23s were still in service as late as 2026.

Fun Facts

  • The MiG-23 could fly faster than the speed of sound — faster than a rifle bullet travels!
  • Its wings could sweep back to three different angles while it was still in the air.
  • The MiG-23 was bigger than the older MiG-21 it replaced, with a much larger fuselage.
  • It was the world's first widely used Soviet fighter that could shoot at planes it could not see with its own eyes.
  • The wings were held to the plane's body by just one pivot pin on each side — simple but strong.
  • A special ground-attack version called the MiG-27 was built using the same basic design.
  • NATO gave it the nickname 'Flogger' — all Soviet planes got a NATO code name starting with a certain letter.
  • Some MiG-23s were still flying in service more than 55 years after the design first took to the skies!

Kids’ Questions

Why did the MiG-23's wings move?

The moving wings helped the plane do different jobs. Swept-back wings made the plane go very fast. Swept-forward wings helped it slow down safely when landing. This made one plane good at many things at once.

What made the MiG-23 better than the older MiG-21?

The MiG-23 could fly farther and carry more weapons. It also had a much better radar to find enemy planes. The older MiG-21 was smaller and could not do all of these things.

What is an afterburner?

An afterburner squirts extra fuel into the engine's hot exhaust. This gives the plane a sudden burst of extra power. It makes the plane go much faster for a short time.

Is the MiG-23 still used today?

Yes! Some MiG-23s were still in service as recently as 2026. That means this design lasted for over 55 years. Not many jet fighters stay in use that long.

Variants

MiG-23M / MF / ML
Soviet front-line air-superiority variants. ML (1976) was the most numerous and capable, with improved Sapfir-23ML radar, lighter airframe, R-24 missile compatibility, and improved manoeuvre limits.
MiG-23MLD
Final Soviet air-superiority variant (1981). Wing leading-edge dogtooth modifications, IRST sensor, R-73 (AA-11 Archer) high-off-boresight IR missile compatibility, and extensive cockpit upgrades. Best-performing Flogger variant.
MiG-23BN / BM / B
Ground-attack variants — the BN was the export ground-attack model (no radar, fixed laser rangefinder, hardened ground-attack avionics), the BM the Soviet-equivalent. 624 BNs widely exported across the Middle East and Africa.
MiG-23UB
Two-seat conversion trainer. Tandem cockpit, full weapons fit, used by every Flogger operator for type conversion training.
MiG-27 Flogger-D / J
Dedicated ground-attack derivative with chiselled nose housing a laser rangefinder, fixed wing intakes, simpler fixed-geometry inlets, and heavy 30mm six-barrel GSh-6-30 cannon. 1,075 built; HAL also produced 165 in India as the MiG-27ML "Bahadur".

Notable Operators

Soviet / Russian Air Force
Primary operator from 1970 until Russian retirement in 1996. Saw combat over Afghanistan from 1980; aerial losses to Stinger MANPADS were significant.
Syrian Arab Air Force
Operated approximately 130 MiG-23M/MS/ML/MF airframes from 1974. Lost 20+ in the 1982 Bekaa Valley engagements against Israeli F-15 / F-16s. Fleet active through the Syrian civil war (2011–present), with airframes lost to ground-based air defences and rebel ground action.
Indian Air Force (historical)
Operated approximately 95 MiG-23BN ground-attack and 24 MiG-23MF interceptor airframes from 1981. Used HAL-built MiG-27 "Bahadur" through 2017. Replaced by Su-30MKI, Mirage 2000, Tejas, and Rafale.
Bulgarian / Cuban / North Korean / Libyan Air Forces (historical and current)
Major Cold War export customers; Bulgaria operated until 2003. North Korean and Cuban Floggers remain in nominal service in 2026. Libyan MiG-23s were used heavily in the 2011 civil war.

Frequently Asked Questions

Why does the MiG-23 have a swing-wing design?

To balance high-speed dash performance with acceptable take-off and landing behaviour. With wings swept fully forward (16°), the MiG-23 has long-span lift for slow flight from short Soviet front-line airfields. With wings fully back (72°), drag is minimised for Mach 2 dash. The 45° intermediate position is used for cruise and combat manoeuvring. The same approach was used contemporaneously on the U.S. F-111 and F-14 Tomcat, and on the European Panavia Tornado. All four designs achieved similar mission flexibility at the cost of mechanical complexity and added weight.

How did the MiG-23 perform in combat against Western fighters?

Poorly when matched against contemporary teen-series fighters with well-trained pilots. In the 1982 Bekaa Valley air battles, Israeli F-15s and F-16s shot down at least 20 Syrian MiG-23s without loss to enemy fighters. In the 1991 Gulf War, U.S. F-15s downed eight Iraqi MiG-23s with no losses. In Afghanistan against Pakistan Air Force F-16s, three MiG-23s were lost to Pakistani fighters. The aircraft's unforgiving handling — particularly the pitch-up tendency at high alpha — disadvantaged it in close visual combat against the highly manoeuvrable F-15 and F-16.

What is the difference between the MiG-23 and MiG-27?

The MiG-27 is a dedicated ground-attack derivative. Visual differences: the MiG-27 has a chiselled, downward-sloping "crocodile" nose housing a laser rangefinder (no radar), simplified fixed-geometry intakes (no variable shock cones), a heavier 30mm GSh-6-30 six-barrel rotary cannon (vs the MiG-23's 23mm GSh-23L), and additional hardpoints with heavier ordnance capacity. The variable-sweep wing, R-29 engine, and overall airframe layout are otherwise identical. 1,075 MiG-27s were built; HAL produced an additional 165 in India.

Why was the MiG-23 retired so early in Russian service?

The end of the Cold War, dramatic post-Soviet defence budget collapse, and the availability of more capable replacements (MiG-29 for air superiority, Su-24 / Su-25 for ground attack) made the maintenance-intensive Flogger fleet uneconomical. The MiG-23 also had a poor accident record, with several variable-sweep wing failures attributed to fatigue at the pivot fitting. Russia retired the type in 1996; many post-Soviet states followed within a decade.

What was the R-23 / R-24 missile, and why was it significant?

The R-23 (AA-7 Apex) was the Soviet Union's first widely deployed semi-active radar-homing beyond-visual-range air-to-air missile, designed specifically for the MiG-23 and tied to its Sapfir-23 radar. The R-23R radar-guided variant offered ~25 km engagement range; the R-23T IR variant offered ~12 km. The improved R-24 (1981) entered service with the MiG-23ML and gave Soviet pilots their first true BVR engagement system. The pair were direct counterparts to the U.S. AIM-7 Sparrow.

Are MiG-23s still flying in 2026?

Yes, in small numbers. North Korea operates an estimated 50 airframes, Cuba retains about 12, Sudan continues to fly the type, and Syrian and Libyan air forces still field active MiG-23s in 2026 although attrition through both civil wars has been heavy. India retired its last MiG-27 "Bahadur" in December 2019. Most other post-Soviet operators retired the type during the 2000s.

How does the MiG-23 compare to the F-14 and F-111?

All three are variable-sweep-wing fighter / strike aircraft of similar era, but they target different missions. The F-14 Tomcat is a dedicated long-range fleet-defence interceptor with the AIM-54 Phoenix and twin engines. The F-111 Aardvark is a long-range strike bomber with internal weapons bay and crew capsule, no air-superiority pretensions. The MiG-23 is a single-engine medium-weight fighter — closer in concept and weight to a single-engine F-15 than to either of the larger U.S. swing-wings.
