The Vympel R-37 (NATO reporting name: AA-X-13/AA-13 Arrow)[2] is a Russian hypersonic air-to-air missile with very long range. The missile and its variants also had the names K-37, izdeliye 610 and R-VD (Ракета Высокой Дальности (Raketa-Vysokoy Dalnosty), "Very Long Range Missile"), and the NATO codenames 'Arrow' and 'Andi'.[3] It was developed from the R-33.

It was designed to shoot down tankers, AWACS and other C4ISTAR aircraft[2] whilst keeping the launch platform out of range of any fighters that might be protecting the target.

DesignEdit

The R-37 was developed from the R-33.[citation needed] For compatibility with aircraft that did not have the MiG-31's sophisticated radar, the semi-active seeker was replaced with a variant of the Agat 9B-1388 active seeker;[2] mid-body strakes enhance lift[2] and hence range, and folding tail controls allow semi-conformal carriage[2] on planes that are not as big as the MiG-31. According to Defence Today the range depends on the flight profile, from 80 nautical miles (150 km) for a direct shot[2] to 215 nautical miles (398 km) for a cruise glide profile.[2] According to Jane's there are two variants, the R-37 and the R-37M; the latter has a jettisonable rocket booster that increases the range to "300-400km" (160–220 nm).[3]

The R-37M designation has since been used for a modernized variant of the missile, also known as RVV-BD (Raketa Vozduh-Vozduh Bolyshoy Dalnosty or English for Long-Range Air-to-Air Missile).. This will be carried by the modernized MiG-31BM and Su-35S fighters.[4] It is not known if the long range air-to-air missile for the Sukhoi Su-57, designated the izdeliye 810, is a derivative of the R-37M.

The missile can attack targets ranging in altitude between 15–25,000 metres. Missiles can be guided semi-actively or actively through Agat 9B-1388 system.[5]

HistoryEdit

The missile was designed in the early 1980s and first flown in 1989.[3] Testing of the R-37 continued through the 1990s[3] in 1994 a trial round scored a kill at a range of 162 nautical miles (300 km).[2] However, the program appears to have been dropped around 1998 on grounds of cost.[3]

Work on the missile appears to have restarted in late 2006,[3] as part of the MiG-31BM program[3] to update the Foxhound with a new radar and ground attack capability.

In 2018, the R-37M had finished its operational validation tests.[6]

ProductionEdit

The R-37 is now in production to equip upgraded Russian MiG-31BM Foxhound interceptors. Despite the early intent to integrate the weapon on the Flanker, this has yet to be reported.[7]
