Mikoyan-Gurevich MiG-21

Updated: October 2026 – A slim tube with a round hole at the front, a pointed triangle as a wing and a small tailplane behind it: anyone who has consciously looked at a MiG-21 once will recognize it anywhere. It is the most-produced supersonic jet in history, flew in dozens of countries and for almost three decades was the backbone of the fighter pilots of the National People’s Army (NVA). Its service in Europe has been over since the end of 2024 – which makes it all the more important to know how to recognize it, which version is in front of you and where you can still find it today.

What is the MiG-21?

The MiG-21 comes from the Soviet design bureau of Artem Mikoyan and Mikhail Gurevich, which had already made a splash in the Korean War with the MiG-15. The task was clearly defined: a lightweight, simple and very fast interceptor that can catch enemy bombers at high altitude and can be built in large numbers.

The first prototype, the Ye-2, flew on February 14, 1955, still with swept wings at that point. Already in June 1955 the Ye-4 followed as the first prototype with the delta wing that later became typical. After several intermediate steps, the MiG-21F entered operational service in 1959. The basic design stayed the same for decades but was enlarged again and again and given more powerful engines, better radar and more armament.

The MiG-21 was not built only in the Soviet Union. Czechoslovakia produced it under license, as did India at Hindustan Aeronautics. China developed the Chengdu J-7 from it, which in turn was exported to many countries. Depending on the count, sources arrive at around 10,000 to 11,500 aircraft not counting the J-7 – no other supersonic jet was produced in such numbers. The design bureau still exists today as the MiG brand and now belongs to the United Aircraft Corporation.

The most important versions

Dozens of variants appeared over the long production run. For spotters and museum visitors the broad lines are enough, because they also differ externally.

Version	Short description	Typical identifying detail
MiG-21F-13	Early day fighter version with a cannon and two infrared-guided missiles	Very slim fuselage, small shock cone, thin spine
MiG-21PF / PFM	All-weather interceptor with radar in the shock cone	Larger air intake and shock cone
MiG-21M / MF	Multirole versions with a built-in twin-barrel GSh-23 cannon	Cannon fairing under the fuselage, thicker spine
MiG-21bis	Last big Soviet production batch with the R-25-300 engine	Pronounced dorsal hump running to the tail
MiG-21U / US / UM	Two-seat trainers (NATO: Mongol)	Two cockpits one behind the other, two-piece canopy
LanceR, Bison, bisD	Modernizations in Romania, India and Croatia	Modern avionics, externally close to the original version

In the NVA the MiG-21PFM carried the designation SPS, after boundary layer control: bleed air from the engine was blown over the flaps, which lowered the landing speed. This designation also appears on many museum signs in eastern Germany.

The technical data of the late MiG-21bis show how compact the jet is despite its Mach 2 performance: around 14.7 meters long without the pitot tube, only 7.15 meters of wingspan, a single Tumansky R-25-300 engine with just under 70 kN of thrust with afterburner. The top speed is around 2,175 km/h at 13,000 meters altitude. The bis is armed with the twin-barrel GSh-23L cannon and carries drop tanks, rocket pods, bombs or air-to-air missiles on five stations.

How to recognize the MiG-21

The MiG-21 is one of those jets you can identify by silhouette alone. Three observations almost always suffice.

That narrows down not only the type but roughly also the generation. The data plate in the museum or the tactical number on the fuselage, with which you can look the aircraft up in databases, settles it definitively. How Bundeswehr registrations are built, which the taken-over NVA MiGs also carried, is explained in the article on Bundeswehr markings.

MiG-21, Mirage or Starfighter?

The most common mix-ups happen with other slim jets of the 1950s and 1960s. The finder helps you narrow it down.

Another candidate is the MiG-15: it also has a round nose intake, but no shock cone, a short, thick fuselage and strongly swept wings instead of a delta. The later MiG-29, by contrast, with two engines, two vertical stabilizers and intakes under the fuselage, hardly resembles it any more. You will find more comparisons between European fighter jets in the guide Recognizing fighter jets in Europe.

The MiG-21 with the NVA

For the East German air force the MiG-21 was the central fighter. The first MiG-21F-13s reached the units in 1962, a total of 76 aircraft of this version by 1964. They went to Fighter Wings 8 and 9 and to a squadron of JG-3. In the mid-1960s the all-weather versions MiG-21PFM followed, designated SPS in the NVA, and later the SPS-K.

In the 1970s the multirole versions were added: from 1972 the NVA received the MiG-21MF, from 1975 the MiG-21bis. Alongside these, the two-seat trainers flew in training, among others with Fighter Pilot Training Wing 15; reconnaissance variants were used by the tactical reconnaissance squadrons. In total East Germany acquired 557 MiG-21s of all versions.

The balance sheet has a serious side. According to the specialist literature, 126 aircraft were lost in accidents, around a quarter of the inventory; at least 54 people lost their lives. That shows how demanding flying the small, fast jet was, which forgave few mistakes at the edge of the envelope.

With reunification in 1990 the Bundeswehr took over 14 MiG-21bis in the “Lasur” version and 27 MiG-21bis SAU. Unlike the more modern MiG-29, which the Luftwaffe still flew for years, the MiG-21s had no future: they were retired in 1992/93. Many aircraft were scrapped, but numerous others were also handed over to museums and collections. That is exactly why so many MiG-21s stand in exhibitions and at former airfields in eastern Germany today – often still in NVA paint, sometimes with the Bundeswehr registrations assigned briefly.

If you are interested in East German aviation as a whole, you will find the civil side in the article on Interflug.

The last operators in Europe

After the end of the Warsaw Pact, the MiG-21 gradually disappeared from European air forces. Some countries modernized it thoroughly, though, and kept it in the air surprisingly long.

Country	Last version	End of flight operations
Slovakia	MiG-21	2002/2003 (depending on the source)
Bulgaria	MiG-21bis / UM	last flight December 31, 2015
Serbia	MiG-21bis / UM	2021
Romania	MiG-21 LanceR	May 15, 2023
Croatia	MiG-21bisD / UMD	end of 2024

Romania had around 110 MiG-21s modernized to the LanceR version by the domestic company Aerostar together with the Israeli Elbit group; the program was completed in 2002. New avionics and Western weapons made the old airframes fit for NATO missions. On May 15, 2023, the Romanian air force officially bid farewell to the last LanceRs; their tasks are taken over by used F-16s.

Croatia was the last European operator. The Croatian air force had also had part of its MiG-21bis and two-seaters overhauled at Aerostar in Romania in the early 2000s. Flight operations ended at the end of 2024, the successor is the Dassault Rafale: Croatia bought twelve used aircraft from France, the first of which landed in Zagreb in April 2024.

Outside Europe the MiG-21 flew even longer. India, one of the largest operators overall with licensed production at HAL, retired its modernized MiG-21 Bisons with a ceremony in Chandigarh on September 26, 2025. In some countries in Africa and Asia, MiG-21s or Chinese J-7s are still in the inventories; how many of them actually fly can hardly be said reliably from the outside.

Where you can see the MiG-21 today

Because the NVA inventories went to many museums after 1990, Germany is a good country for MiG-21 fans. A few places to go:

Location	What awaits you
Military History Museum Berlin-Gatow	Several versions, including MiG-21bis SAU, MF, UM and SPS
Technik Museum Sinsheim	MiG-21 in the outdoor exhibition
Wernigerode Aviation Museum	MiG-21 SPS from NVA inventories
Letecké muzeum Kbely, Prague	Large collection of Czechoslovak military jets
Polish Aviation Museum in Krakow	Extensive collection of Warsaw Pact jets

You reach the museum in Gatow through the spot guide Luftwaffe Museum at Berlin-Gatow airfield. For Prague and Krakow there are dedicated spot pages for the Letecké muzeum Kbely and the Muzeum Lotnictwa Polskiego. Which aircraft are currently on display, in restoration or on loan there changes – a look at the museum’s website before your visit is worthwhile.

In addition, many MiG-21s stand in eastern Germany in smaller collections, club museums and as memorials at former airfields, for example in Rothenburg in Upper Lusatia. Many of these projects live from volunteers; how you can take part is covered in the article on Volunteering at aviation museums.

Photo tips for museum MiGs

A MiG-21 in a museum is a rewarding but tricky subject: small, slim and often parked tightly between other jets.

Common mix-ups and how to rule them out

Conclusion

The MiG-21 is a piece of the Cold War you can touch: simply built, fast, produced in huge numbers and flown in dozens of countries. For Germany it is inseparably tied to the NVA, whose fighter pilots it shaped for almost three decades. Since Romania in 2023 and Croatia in 2024 retired it, it has vanished from European airspace – but in the museums between Berlin, Prague and Krakow it is more present than ever.
