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-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, in 1995–2002. 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.
  MiG-21bis-D (D = Dorađen ("Upgraded"))
  Upgraded in 2003, by Aerostar SA, for the Croatian Air Force with some elements of the LanceR standard. Modernized for NATO interoperability including a Honeywell ILS (VOR/ILS and DME), a GPS receiver, a new IFF system and communications equipment from Rockwell Collins.
  MiG-21UMD (D = Dorađen)
  Croatian designation for four MiG-21UM upgraded for NATO interoperability, similarly to the MiG-21bis-D.
  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 a Helmet Mounted Sight, the ability to fire High Off-Boresight missiles like the R-73 (missile) and a 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.
