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 1984.[4]

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 1984.[4]

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.[5] 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-27/33, 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.[6] 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.

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.[7] Russia currently receives new improved air-to-air missiles on the basis of the R-73.[8]

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 Su-57 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.[9][10]

Operational history

On 24 February 1996, two Cessna 337s of the Brothers to the Rescue were shot down by a Cuban Air Force MiG-29UB. Each of the aircraft was downed by an R-73 missile.[11]

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.[12]
