. Work began in 1973, and the first missiles entered service in 1982.

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 (18.6 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
AIM-9 Sidewinder
The AIM-9 Sidewinder is a heat-seeking, short-range, air-to-air missile carried mostly by fighter aircraft and recently, certain gunship helicopters. The missile entered service with United States Air Force in the early 1950s, and variants and upgrades remain in active service with many air forces...

 service in 1997. The R-73M has greater range and a wider seeker angle (to 60° off-boresight), as well as improved IRCCM (Infra-Red Counter-Counter-Measures).

An improved version of the R-73M, the R-74M 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-35BM.

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

 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 (one having been scored with 30mm cannon fire, while one of the no less than 24 R-27 medium-range missiles resulted in the other).
