The R-73 is an infrared homing (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 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-50/52.
The R-73 is a highly maneuverable missile and mock dogfights between USAF and German Air Force MiG-29s (inherited from the former Air Forces of the National People's Army) equipped with the R-73/helmet mounted cueing 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. The R-73 prompted the development of a number of western air-to-air missiles including the 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). Further developments include the R-74 (izdeliye 740) and its export variant RVV-MD. Russia currently receives new improved air-to-air missiles on the basis of the R-73.
An improved version of the R-74, the K-74M (izdeliye 750) features fully digital and re-programmable systems, and is intended for use on the MiG-35 or MiG-29K/M/M2 and Su-27SM, Su-30MK and Su-35S. A further upgrade, known as the K-74M2 (izdeliye 760), is intended for the fifth-generation Sukhoi PAK FA aircraft. This missile has reduced cross section to fit in internal weapon bays and will match the performance of the AIM-9X and the ASRAAM. A clean sheet design, the K-MD (izdeliye 300), will supersede the K-74M2 in the future.
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 destroyed the UAV with an R-73 missile. The incident was one of many that led up to the 2008 Russo-Georgian conflict.
