The Vympel R-73 (NATO reporting name AA-11 Archer) developed by Vympel machine Building Design Bureau, is the most modern Russian short-range air-to-air missile.
[edit] Development
The R-73 was developed to replace the earlier R-60 (AA-8 'Aphid') weapon for short-range use by Soviet fighter aircraft. Work began in 1973, and the first missiles entered service in 1985.
The R-73 is an infrared-guided (heat-seeking) missile with a sensitive, cryogenic cooled seeker with a substantial "off-boresight" capability: the seeker can "see" targets up to 60° off the missile's centerline. It can be targeted by a helmet-mounted sight (HMS) allowing pilots to designate targets by looking at them. Minimum engagement range is about 300 meters, with maximum aerodynamic range of nearly 30 km (18.75 mi) at altitude.
The R-73 is a highly maneuverable missile that in most respects is believed to be superior to the United States AIM-9M Sidewinder. Mock dogfights indicated that the high degree of "off-boresight" capability of the R-73 would make a significant difference in combat. This prompted the development of Sidewinder and other SRM successors like AIM-132 ASRAAM, IRIS-T, MICA IR, Python IV and the latest Sidewinder variant, AIM-9X, that entered squadron service in 2003.[citation needed]
From 1994 the R-73 has been upgraded in production to R-73M standard, which entered CIS service in 1997. The R-73M has greater range and a wider seeker angle (to 60° off-boresight), as well as improved IRCCM (InfraRed Counter-Counter Measures).
The weapon is used by the MiG-29, Su-27, Su-32 and Su-35, and can be carried by newer versions of the MiG-21, MiG-23, Sukhoi Su-24, and Su-25 aircraft. India is looking to use the missile on their HAL Tejas. It can also be carried by Russian attack helicopters, including the Mil Mi-24, Mil Mi-28, and Kamov Ka-50.
