Variants

All information in this section adapted from MiG-21 (2008).

Development and Preproduction - Generation Zero (1954–1956)

Ye-1 (1954)

Preliminary swept-wing design around the Mikulin AM-5A non-reheated turbojet. Instead of building it, the design was quickly reworked into the Ye-2.

Ye-2 (1954; NATO: "Faceplate")

Swept-wing prototype with Mikulin AM-9B reheated turbojet, armed with three NR-30 cannon, and could carry one UB-16-57 rocket pod. Fitted with RSIU-4 VHF radio, Uzel IFF interrogator, ARK-5 Amur automatic direction finder with RUP landing approach computer, MRP-48P Dyatel marker beacon receiver, SRO-2 Khrom IFF transponder, Sirena-2 RWR, SRD-1M Radal'-M radar rangefinder linked to an ASP-5N computing gunsight. Ye-2 made its maiden flight on 14 February 1955, but programme was abandoned when Mikulin RD-11 turbojet became available.

Ye-2A (1955; aka "MiG-23")

Ye-2 design modified for RD-11 turbojet. Six built. Identical to Ye-5 except for wings: Ye-2A had swept wings. Fitted with RSIU-4V radio, ARK-5 ADF with RUP module, MRP-48P marker beacon receiver, Bariy-M IFF transponder, Sirena-2 RWR, SRD-1M Radal'-M radar rangefinder with ASP-5N-V3 computing gunsight.

Ye-4 (1955)

The first delta wing prototype of the MiG-21. Proof-of-concept testbed: used an existing production engine in a Ye-5 airframe.

Ye-50 (1956)

Swept-wing, experimental high-altitude interceptor. Ye-2 airframe modified to fit Dushkin S-155 rocket motor. Design work started in 1954, first flight in 1956. Programme terminated after crash of Ye-50/3 on 8 August 1957.

Ye-50A (1956)

Not to be confused with MiG-23 "Flogger." The Ye-50A was a refinement of the Ye-50; was to enter production and service with the designation "MiG-23U," but this didn't happen due to unavailability of the intended R11E-300 turbojet.

Ye-5 (1956)

Delta wing research prototype powered by Mikulin AM-11 turbojet. Some changes besides the engine were made from the Ye-4, including addition of a second hydraulic system. The initial designation was I-500.

MiG-21 (1956; Izdeliye 65; NATO "Fishbed-A")

The first series of fighters, production version of Ye-5. Five units built at Tbilisi, but not continued due to efforts having been redirected towards the more advanced Ye-6/MiG-21F. The aircraft that were built found work as testbeds.

Initial Mass Production - Generation One (1957–1961)

Ye-6 (1957)

Three pre-production versions of MiG-21F.

Ye-50P (1958)

Rocket-boosted high-altitude interceptor project, terminated before construction.

MiG-21F (1959; Izdeliye 72; NATO "Fishbed-B")

F = Forsirovannyy ("uprated")Single-seat day fighter aircraft. It was the first production aircraft, with 93 machines being made (20 in 1959, 73 in 1960). The MiG-21F carried 2160 liters of fuel in six internal fuel tanks and was powered by an R11F-300 turbojet engine with 5740kgf of thrust. The earliest units were fitted with one NR-30 and two NR-23 cannon, subsequent aircraft were armed with two 30-mm NR-30 cannons 60 shells each, it was also capable of carrying two bombs ranging from 50 to 500 kg each. Avionics included PUS-36D weapons sequencing module, R-800 communications radio, ASP-5NV-U1 computing gunsight, and SRD-5MN Baza-6 radar rangefinder.

Ye-6T (1958)

Prototypes based on MiG-21F used for testing the Vympel K-13 (NATO: AA-2 'Atoll') missile system. The aircraft were later reused for other tests.

MiG-21P-13 (aka Ye-7) (1958)

P = Perekhvatchik ("interceptor")13 = refers to K-13 missile systemTwo MiG-21 sans suffixe (izdeliye 65) were converted to use K-13 missile system as part of a development project for an interceptor armed with the K-13 missile. Due to the MiG-21P-13 project lagging behind schedule, it was decided to produce the existing MiG-21F with the capability to use the K-13 missile system, resulting in the MiG-21F-13. The development continued, however, eventually resulting in the MiG-21PF.

MiG-21F-13 (1960; Izdeliye 74; NATO "Fishbed-C")

F = Forsirovannyy ("Uprated")13 = refers to K-13 missile systemShort-range day fighter; the MiG-21F-13 was the first MiG-21 model to be produced in large numbers. Unlike the MiG-21F, the MiG-21F-13 had only one NR-30 cannon on the starboard side, with only 30 rounds; however, it added the capability to use the K-13 missile system, of which two could be carried on underwing hardpoints. On early-production MiG-21F-13s the launch rails were of the APU-28 type; later models had these replaced by APU-13 rails. The launch rails were removable, allowing the MiG-21F-13 to carry two UB-16-57 unguided rocket launchers, two S-24 rockets on PU-12-40 launch rails or two FAB-100/250/500 bombs or ZB-360 napalm tanks. The F-13 had further upgrades: an improved ASP-5ND optical gunsight and an upgraded SRD-5ND ranging radar. The MiG-21F-13 was also built under licence in China as the Chengdu J-7 or F-7 for export, as well as in Czechoslovakia as the Aero S-106, though the S-106 designation was not used for long; subsequently, the Czech-built units were referred to as "MiG-21F-13" just like the Soviet-built aircraft.

Ye-6V (1961; NATO "Fishbed-E")

Experimental STOL version of MiG-21F-13 with JATO boosters.

Interceptors - Generation Two (1961–1966)

MiG-21PF (1961; Izdeliye 76; NATO "Fishbed-D")

P = Perekhvatchik ("Interceptor")F = Forsirovannyy ("Uprated")Production version of the all-weather interceptor. These were powered by the R11F2-300 turbojet and, starting with the seventh production batch, fitted with the RP-21 radar (the first six batches used the older TsD-30T radar (aka RP-9-21). Further, the weapons control system was modified from that of the F-13 to allow use of the RS-2US (aka K-5MS) beam-riding AAM in addition to the IR-seeking K-13.

MiG-21FL (1965; Izdeliye 77)

F = Forsazh ("Reheat")L = Lokator ("Radar")Export (Third world) model of the MiG-21PF. Downgraded from baseline MiG-21PF with older and less powerful R11F-300 engine, no provision for carrying RS-2US beam-riding missiles and a simplified, downgraded version of the RP-21 radar, designated R1L. Wide-chord fin and brake chute fairing at its base. Built under license in India as the Type 77.

Ye-7SPS (1961)

SPS = Sduv Pogranichnovo Sloya ("Boundary Layer Blowing")Testbed to develop flap-blowing system, rebuilt from Ye-6V/2.

MiG-21PFS (1963; Izdeliye 94; NATO "Fishbed-D/F")

P = Perekhvatchik ("Interceptor")F = Forsirovannyy ("Uprated")S = Sduv Pogranichnovo Sloya ("Boundary Layer Blowing")Production version of Ye-7SPS.

Ye-7M

Further development of the Ye-7SPS; prototype for MiG-21PFM.

MiG-21PFM (1964; Izdeliye 94; NATO "Fishbed-F")

P = Perekhvatchik ("Interceptor")F = Forsirovannyy ("Uprated")M = Modernizirovannyy ("Modernised")The production version of the Ye-7M was a modernised MiG-21PF, with an upgraded RP-21M radar, SRZO-2 Khrom-Nikkel IFF transponder and other changes in avionics. Further, later-production PFMs reintroduced cannon armament, in the form of the capability to carry a GSh-23 cannon and 200 rounds in an underbelly pod. Following tests in 1966, MiG-21PFM aircraft built after 1968 could carry the Kh-66 air-to-surface missile.

Ye-7R

Prototypes of the MiG-21R combat-capable reconnaissance aircraft derived from MiG-21PFS.

MiG-21R (1965; Izdeliye 03/94R; NATO "Fishbed-H")

Initially designated Izdeliye 03 to confuse outsiders, the MiG-21R's official "type" designation was Izdeliye 94R. The first production unit was rolled out in early 1966 and production continued until 1971. For recce missions, the MiG-21R could carry a Type D daylight PHOTINT pod, a Type N nighttime PHOTINT pod, a Type R general-purpose ELINT pod or a Type T pod housing a TV system, making the MiG-21R one of the first Soviet recce aircraft to make use of ELINT equipment. Small changes were made throughout the production run. Early-production units had the R11F2S-300 turbojet, which was replaced in later machines by the R13-300 powerplant. In the air-to-air role, the MiG-21R could carry two RS-2US or R-3S AAMs, and in the strike role it could be loaded with two UB-16-57UM or UB-32 rocket pods, two S-24 heavy unguided rockets or two bombs of up to 500kg weight (each).

Ye-7S (1963)

Tactical fighter prototype - a production MiG-21PF converted into an avionics testbed to test the Sapfir-21 fire-control radar.

MiG-21S (1964; Izdeliye 95; NATO "Fishbed-J")

S = Sapfir (referring to the Sapfir-21/RP-22 radar).The production version of the Ye-7S. This was fitted with the RP-22 radar (production version of the Sapfir-21 radar) working together with a ASP-PF-21 computing gunsight. The airframe was different from that of the MiG-21PFM by using the same saddle tank as in the MiG-21R. The MiG-21S had an R11F2S-300 powerplant and an AP-155 autopilot featuring a 'panic button' autorecovery system. The MiG-21S could carry the GP-9 cannon pod. It had four underwing hardpoints, with the two outboard pods being "wet", that is, they could carry drop tanks. It could carry all weapons that the MiG-21PFM could, with the addition of the R-3R (K-13R) missile, the semi-active radar homing variant of the K-13. MiG-21S was produced from 1965 to 1968 and delivered only to the Soviet air force.

MiG-21N (1965; Izdeliye 95N; NATO "Fishbed-J")

'N = Nositel ("Carrier")Also known as MiG-21SN, this was a variation of the MiG-21S capable of delivering one RN-25 tactical nuclear weapon.

MiG-21PD (1966; Izdeliye 23-31/92)

PD = Podyomniye Dvigateli ("Lifting Engines")STOL technology demonstrator built out of a MiG-21PFM airframe.

Modernisation - Generation Three (1968–1972)

MiG-21M (1968; Izdeliye 96; NATO "Fishbed-J")

M = Modernizirovannyy ("Modernised")Export variant of the MiG-21S with two major differences: the RP-22 radar of the MiG-21S was substituted with the older RP-21MA radar, and featured a built-in GSh-23L cannon instead of a cannon pod. In the air-to-air role it could only carry the R-3S IR-seeking AAM on its four pylons, as the SARH variant, the R-3R, was not cleared for export. The type was also licence-built in India, the first Indian-built example being delivered in February 1973.

MiG-21I (1968; Izdeliye 21-11; "Analog")

I = Imitator ("Simulator")Testbed for the wing design of the Tu-144 (NATO "Charger") supersonic transport.

MiG-21K (1969; proposal)

This was a proposed variant of the MiG-21 for a dedicated ground attack role; the Mikoyan proposal was withdrawn before phase two of the competition, which was eventually won by the Su-25.

MiG-21Sh (1969; Izdeliye 21-32"; project)

Sh = ShturmovikThis was another ground-attack project that was a "fusion" of the MiG-21 and the MiG-27; it was referred to alternatively as MiG-21Sh and MiG-27Sh. Cancelled due to the MiG-23/27 offering higher performance.

MiG-21SM (1969; Izdeliye 15/95M; NATO "Fishbed-J")

S = Sapfir (referring to the Sapfir-21/RP-22 radar).M = Modernizirovannyy ("Modernised")Upgrade of the MiG-21S using the R13-300 engine and with a built-in GSh-23L cannon, as well as a considerably updated avionics package.

MiG-21MF (1970; Izdeliye 96F; NATO "Fishbed-J")

M = Modernizirovannyy ("Modernised")F = Forsirovannyy ("Uprated [engine]")Export version of the MiG-21SM, with RP-22 radar and R13-300 turbojet. The choice of weapons loads was increased with the addition of the R-60 (NATO: AA-8 "Aphid") and later the R-60M IR-seeking AAM. These were also licence-built in India by HAL as the Type 88.

MiG-21DF (1969)

D = Dal'nomer ("Rangefinder")F = Forsirovannyy ("Uprated")A production MiG-21 (S or SM) refitted with R13F2-300 engine and Kvant radar rangefinder for test purposes. Though testing revealed an improvement in manoeuvrability, this variant was not put into production.

MiG-21SMF (1970)

S = Sapfir (referring to the Sapfir-21/RP-22 radar).M = Modernizirovannyy ("Modernised")F = Forsirovannyy ("Uprated [engine]")A testbed aircraft - a stock MiG-21SM refitted with the uprated R13F2-300 turbojet. Though a prototype for what would have been a new model, it never entered production.

MiG-21MT (1971; Izdeliye 96T; NATO "Fishbed-J")

M = Modernizirovannyy ("Modernised")T = Toplivo ("Fuel," referring to increased fuel capacity)This was a MiG-21MF with increased fuel capacity. Though designed for export, only 15 were built and none were exported.

MiG-21SMT (1971; Izdeliye 50; NATO "Fishbed-K")

S = Sapfir (referring to the Sapfir-21/RP-22 radar).M = Modernizirovannyy ("Modernised")T = Toplivo ("Fuel," referring to increased fuel capacity)A development of the MiG-21SM with increased fuel capacity. This variant is easily spotted thanks to its larger spine.

MiG-21ST (Izdeliye 50)

S = Sapfir (referring to the Sapfir-21/RP-22 radar).T = Toplivo ("Fuel," referring to increased fuel capacity)Due to the extreme unpopularity of the MiG-21SMT amongst Soviet pilots, most were rebuilt with the smaller saddle tank of the MiG-21bis after that type entered production in 1972. Following the conversion, they were redesignated MiG-21ST and were externally indistinguishable from the MiG-21bis.

MiG-21bis (1972; Izdeliye 75; NATO "Fishbed-L/N"

The ultimate development of the MiG-21, fitted with the Tumanskiy R25-300 turbojet engine and a great number of other advances over previous types. Those MiG-21bis for the Soviet PVO (Air Defence Force) were equipped with the Lazur GCI system (NATO: "Fishbed-L"), while those for the Soviet Air Force were fitted with the Polyot ILS system (NATO: "Fishbed-N").

Trainer Variants (1960–1968+)

Ye-6U (1960)

Trainer prototype based on the Ye-6T.

MiG-21U (1961; Izdeliye 66-400; NATO "Mongol-A")

U = Uchebnyy ("Training")Two-seat training version of the MiG-21F-13.

MiG-21UR (1961; project)

U = Uchebnyy ("Training")R = Razvedchik ("Reconnaissance")This was an unrealised project based on the Ye-6U in which the rear cockpit was transformed into an extensive camera bay.

MiG-21U (1965; Izdeliye 66-600; NATO "Mongol-B")

Essentially the same as the 66-400, but with the wide-chord vertical stabiliser as on the MiG-21PFM.

MiG-21US (1966; Izdeliye 68; NATO "Mongol-B")

U = Uchebnyy ("Training")S = Sduv [Pogranichnovo Sloya] ("[Boundary Layer] Blowing")Two-seat training version; upgrade of MiG-21U 66-400 with blown flaps.

MiG-21UM (1968; Izdeliye 69; NATO "Mongol-B")

U = Uchebnyy ("Training")M = Modernizovannyy ("Modernised")Two-seat training version of the MiG-21MF. Type 69 Indian Air Force designation.

Upgrade programmes

MiG-21-93

Russia now offers an upgrade package to bring late-model MiG-21s up to the MiG-21-93 standard. This package provides an upgrade of the avionics suite that includes installation of the Kopyo pulse-doppler radar, smaller version of N010 Zhuk airborne radar used by the MiG-29, which enables the aircraft to fire a greater range of modern weapons such as the beyond-visual-range Vympel R-77 air-to-air missile. The upgraded avionics also enhance the aircraft's survivability as well as its ability to engage enemy fighters. Other upgrade features include installation of a dual-screen HUD, helmet-mounted target designator and advanced flight control systems.

MiG-21-2000

Single-seat 21st century version for export buyers. Made by Israel Aerospace Industries.

MiG-21 LanceR

Upgraded version for the Romanian Air Force done by Elbit Systems of Israel and Aerostar SA of Romania. The LanceR-A version is optimized for ground attack being able to deliver precision guided munitions of eastern and western origin as well as R-60, R-73 and Python III air-to-air missiles. The LanceR-B version is the trainer version and the LanceR-C version is the air superiority version featuring 2 LCD MFDs, helmet mounted sight and the Elta EL/M-2032 Air combat radar.[2]

MiG-21 Bison

Upgraded version for export, the Indian Air Force being the first customer. Equipped with the Phazotron Kopyo (Spear) airborne radar, which is capable of simultaneously tracking 8 targets and engaging 2 of them with semi-active radar homing air-to-air missiles, such as the Vympel R-27. The radar also enables the fighter to deploy active radar homing air-to-air missiles such as the Vympel R-77 when an additional channel is incorporated. Russia has claimed that this version is equivalent to the early F-16. The Indian Air Force has since then upgraded its avionics with the addition of Helmet Mounted Sight (HMS), ability to fire High Off-Boresight missiles like the R-73 (missile) and Tactical Data Link, improving further its already formidable WVR Combat capability, and has performed very well even against F-15C Eagles in Cope India and Red Flag Exercises.

MiG-21-97

MiG-21-93 upgrade. MiG-21-93 re-engined with the Klimov RD-33 engine. The Russians have claimed that the evaluation at Ramenskoye Airport had shown that this version has beaten simulated F-16 in a mock dogfight with a score of 4:1.

Foreign-built variants

China (PRC)

Chinese-built variants of the MiG-21 are designated Chengdu J-7 and F-7 (for export). Only the initial version of the J-7 was a copy of a MiG-21 variant, namely the MiG-21F-13. Though an agreement had been reached between China and the USSR for licence production of the MiG-21 in China, political relations soured between the two countries, causing Soviet assistance to stop. The Chinese reverse-engineered parts of the handful of MiG-21F-13s supplied from the USSR, in order to make up for blueprints and documentation that had not yet been shipped over from the USSR at the time of the political rift. All subsequent development of the J-7 was indigenous to China and different from Soviet-made versions. The Guizhou JL-9 trainer, first flown in 2003, is also based on the MiG-21 airframe.

Czechoslovakia

Between 1962 and 1972 the MiG-21F-13 version was manufactured under license by Aero Vodochody, in Czechoslovakia. Aero Vodochody (then Středočeské strojírny, n.p.), built a total of 194 planes during this period, under the cover designation article Z-159. It followed the MiG-15 and MiG-19S built in Vodochody factory from the fifties to sixties. The sole locally built version of the MiG-21F-13 differed externally from the Soviet-built examples by the solid dural sheet fairing behind the cockpit canopy, as opposed to the transparent one on the original Soviet MiGs. These machines were built for the Czechoslovak Air Force and also for export. The R13-300 engines were imported from the Soviet Union.

India

The production of the MiG-21s in India under license by Hindustan Aeronautics in Nasik started with the MiG-21FL in 1966 in four phases starting with the assembly of CKD kits, moving on to subassemblies, parts, and finally advancing to production from scratch. 205 MiG-21FLs, designated Type 77 and nicknamed Trishul ("Trident), were built in India between 1966 and 1972; the first one built entirely from Indian-made components was delivered to the IAF on 19 October 1970, with the first Indian-made R11F2S-300 powerplant leaving the assembly line on 2 January 1969. In 1971 HAL production was switched to an improved version of the MiG-21M (izdeliye 96), which was designated Type 88 by HAL; as this variant was produced exclusively in India, no izdeliye designation is applicable. The first Type 88 MiG-21M was delivered to the IAF on 14 February 1973 and the last on 12 November 1981, with a total of 158 built. The last variant to be produced by HAL was the MiG-21bis. A total of 75 were built in 1977 from CKD kits, and a further 220 were built from scratch by 1984. Despite a series of crashes during the 1990s, the Indian Air Force has decided to upgrade about 125 of the MiG-21bis in its inventory to the MiG-21 "Bison" standard. Those can serve until 2025. The original MIG-21 FL (MIG-21 PF or Type 77) was retired in December 2013; remaining MIG-21M aircraft (Type 88) are scheduled to be retired by 2015.
