High performance of the MiG-21 aircraft, which is the most popular supersonic fighter in the world, enables to effectively solve a wide range of flight missions even today.
The RAC "MiG" jointly with the SOKOL aircraft-building plant of Nizhniy Novgorod and in cooperation with other Russian enterprises and organizations have worked out the upgrade program of the MiG-21 family aircraft, aimed at expansion of armament nomenclature and modes of its application that allow these aircraft to be still successfully operated by Air Force of different countries for some years. Combat capabilities of upgraded MiG-21 aircraft correspond to those of the up-to-date fourth generation fighters.
In 1998-2005 the Indian Air Force upgraded fundamentally 125 MiG-21 fighters on the basis of the MiG-21-93 project developed by the RAC "MiG". In the course of upgrading the MiG-21bis was equipped with a new armament control system including the multi-function radar "Kopyo", helmet-mounted target designation system, data display equipment based on the up-to-date head-up and multifunctional displays.
The radar "Kopyo", designed by the "Fazatron-NIIR" Corporation, provides for the acquisition and attack of targets (including with the middle-range missiles) in look-up and look-down as well as the detection of radar-contrast surface and ground targets. The radar "Kopyo" is capable to track up to 8 targets and attack simultaneously two most dangerous ones. The radar has the terrain mapping mode.
The fighter is equipped with new systems of navigation, communication, electronic counter measure, video recording, integrated system of monitoring, recording and processing of the flight data.
The electrical supply and air conditioning systems have been improved.
The fighter weapon suite is significantly expanded: it is added with RVV-AE, R-27R1, R-27T1, R-73E "A-A" missiles and KAB-500Kr guided bombs. Concurrently with upgrading the aircraft service life and lifetime can be extended.
At the customer’s request the available MiG-21 aircraft of the customer can be subjected to upgrading of various complexity level and provided with equipment and armament of foreign production.
