The Vympel R-37 (NATO reporting name: AA-X-13/AA-13 Arrow)[1] is a Russian air-to-air missile with very long range. The missile and its variants also had the names K-37, izdeliye 610 and R-VD (Raketa-Vysokaya Dalnost, "Very Long Range Missile"), and the NATO codename 'Andi'.[2] It was developed from the R-33 (missile).
It was designed to shoot down AWACS and other C4ISTAR aircraft[1] whilst keeping the launch platform out of range of any fighters that might be protecting the target.
Design
The R-37 was developed from the Vympel R-33. 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;[1] mid-body strakes enhance lift[1] and hence range, and folding tail controls allow semi-conformal carriage[1] 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[1] to 215 nautical miles (398 km) for a cruise glide profile.[1] 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).[2]
The R-37M designation has since been used for a modernized variant of the missile, also known as RVV-BD. This will be carried by the modernized MiG-31BM and Su-35S fighters. It is not known if the long range air-to-air missile for the PAK FA, designated the izdeliye 810, is a derivative of the R-37M.
Altitude 15–25000 m.[3]
History
The missile was designed in the early 1980s and first flown in 1989.[2] Testing of the R-37 continued through the 1990s;[2] in 1994 a trial round scored a kill at a range of 162 nautical miles (300 km).[1] However, the program appears to have been dropped around 1998 on grounds of cost.[2]
Work on the missile appears to have restarted in late 2006,[2] as part of the MiG-31BM program[2] to update the Foxhound with a new radar and ground attack capability.
Production
The R-37 is now in production to equip upgraded Russian MiG-31BM Foxhound interceptors, and export MiG-31BM aircraft for Syria(??). Despite the early intent to integrate the weapon on the Flanker, this has yet to be reported.[4]
