R-37 (missile)

The Vympel R-37 (NATO reporting name: AA-X-13/AA-13 Arrow) 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'. It was developed from the R-33 (missile).

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

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; mid-body strakes enhance lift and hence range, and folding tail controls allow semi-conformal carriage 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 to 215 nautical miles (398 km) for a cruise glide profile. 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).

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.
