context_page_description: This is a list of variants and specifications for variants of the Mikoyan-Gurevich MiG-21, which differed considerably between models.
context_section_description: 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-21PF (1961; Izdeliye 76A)
  Version for export to Warsaw Pact countries; only difference from domestic version was the IFF equipment.
  MiG-21PFL (1966; Izdeliye 76A)
  L = Lokator ("Radar")
  Version of MiG-21PF tailored to a Vietnamese requirement. The "L" designation may be short for lokator to reflect the different sensor suite in this version as compared to the standard PF.
  MiG-21PFM (Izdeliye 76A)
  M = Modifiziert ("Modified")
  Not to be confused with the "real" MiG-21PFM which is izdeliye 94. This was an East German designation for MiG-21PF aircraft with upgraded RP-21 radars.
  MiG-21RFM (Izdeliye 76A)
  R = Lokator ("Radar"), F = Forsaj ("Reheat"), "M" = "Modernizat" ("Modernised")
  Romanian designation for the MiG-21PF.
  MiG-21Ye
  Remote-controlled drones converted from MiG-21PF; also designated M-21 (M = mishen', "target").
  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.
  MiG-21PFS (Izdeliye 94; NATO "Fishbed-D")
  The first nine production batches of the MiG-21PFS were externally identical to the MiG-21PF but with blown flaps and brake chute fairing at the fin's base.
  MiG-21PFS (Izdeliye 94; NATO "Fishbed-F")
  From batch 10 to batch 19, the large-chord vertical stabiliser first seen on the MiG-21FL was introduced, but the aircraft retained the SK ejection seat and one-piece, forward-opening canopy of the MiG-21PF.
  MiG-21PFS (Izdeliye 94; NATO "Fishbed-F")
  From c/n 941314 onwards, MiG-21PFS aircraft had the wide-chord tail, a KM-1 ejection seat and a two-piece, sidewards-opening canopy.
  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.
  MiG-21PFM (1964; Izdeliye 94A; NATO "Fishbed-F")
  Export version with a different IFF system and no capacity to carry S-24 rockets or ZB-62 napalm tanks.
  MiG-21PFM (Izdeliye 94N; NATO "Fishbed-F")
  Nuclear-capable version of MiG-21PFM.
  MiG-21PFMA (Izdeliye 94A)
  Polish designation of standard MiG-21PFM.
  MiG-21PFMN (Izdeliye 94N)
  Polish designation of nuclear-capable MiG-21PFM.
  MiG-21RFMM (Izdeliye 94A)
  R = Radar, F = Fortaj ("Reheat"), M = Modernizat ("Modernised")
  Romanian designation for the MiG-21PFM.
  MiG-21SPS (Izdeliye 94A; NATO "Fishbed-F")
  SPS = Sduv Pogranichnovo Sloya ("Boundary Layer Blowing")
  To avoid confusion with the local "MiG-21PFM" designation given to the modified MiG-21PF (izdeliye 76A), the East Ge
