The Vympel R-73 (NATO reporting name AA-11 Archer) is a short-range air-to-air missile developed by Vympel NPO that entered service in 1982. At the time of its introduction, it was the most advanced short range missile in the world.
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 40° 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 (19 mi) at altitude.
The R-73 is a highly maneuverable missile and mock dogfights have indicated that the high degree of "off-boresight" capability of the R-73 would make a significant difference in combat. The missile also has a mechanically simple but effective system for thrust-vectoring. Altogether, this prompted the development of the Sidewinder and other SRM successors like AIM-132 ASRAAM, IRIS-T, MICA IR, Python IV and the latest Sidewinder variant, the AIM-9X which entered squadron service in 2003.
From 1994, the R-73 has been upgraded in production to the 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, MiG-31, Su-27, Su-34 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.
During the Eritrean-Ethiopian War from May 1998 to June 2000, R-73 missiles were used in combat by both Ethiopian Su-27s and Eritrean MiG-29s. It was the IR-homing R-60 and the R-73 that were used in all but two of the kills.
On 18 March 2008, a MIG-29 Fulcrum of the Russian Air Force intercepted a Georgian Elbit Hermes 450 UAV over Abkhazia. The MIG-29's pilot launched a single R-73 missile at the UAV. The missile struck the UAV and destroyed it.
