Self Defence: Depends on the version of the aircraft.
Comments: The MiG-21 forms 16 operational squadrons, in a number of variants, and is the ageing backbone of the Indian Air Force. 125 MiG-21bis are selected to be upgraded by MiG-MAPO and HAL. Reportedly another 50 aircraft will be upgraded, after the 125 initial order. The first two aircraft were upgraded in Russia, with the first test flight occurring in October 1998 and trials of the medium-range R-73RDM2 and the long-range R-77RVV-AE air-to-air missiles being conducted in February 1999. These two aircraft have returned to India and as of July 2001, four aircraft have been upgraded adding to the first two. Test flights began in June 2001, while HAL has confirmed that modernisation is taking place. All aircraft will be upgraded locally at HAL and will be completed by 2004. The aircraft will be designated by the IAF as the MiG-21 Bison.
The upgrade consists of Phazotron NIIR's Kopyo multimode, X-band pulse Doppler radar, new nosecone, new canopy, single-piece windshield and new canopy made of stressed acrylic composites, Sextant's TOTEM RLG-INS with NSS-100P GPS embedded GPS receivers, El-Op HUD, Sextant MFD-55 LCD display, autopilot, DRDO's Tarang radar warning receivers (RWR), digital flight data recorder, new liquid air cooling system, HOTAS controls, a SURA helmet mounted sight, stores management system, digital air data computer system, short range radio navigation system, new HF/VHF/UHF radios, twin conformal Vympel flare dispensers (26mm, 120 rounds) and a new electric power supply system. Reportedly the new RWR to be fitted, is an indigenous system developed by DRDO and goes by the name Tarang. A modified version of this RWR will be used aboard the Su-30MKI.
The upgrade package was jointly developed and certified by the IAF, and Russia's Sokol Nizhny Novgorod aircraft building plant and the state-owned avionics testing & integration establishment.
