The Vympel R-37M (NATO reporting name: 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 RVV-BD (Ракета Воздух-Воздух Большой Дальности (Raketa Vozduh-Vozduh Bolshoy Dalnosti), "Long range air-to-air missile"), and the NATO codenames 'Axehead' and 'Andi'. [3] It was developed from the R-33.

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

History

The missile was designed in the early 1980s and first flown in 1989. [3] Testing of the R-37 continued through the 1990s, [3] and 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 to update the Foxhound with a new radar and ground attack capability. [3]

In 2018, the R-37M had finished its operational validation tests. [4] [5]

Production

The R-37 is now in production to equip upgraded Russian MiG-31BM interceptors.

Design

The R-37 was developed from the 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. [2] Similarly, folding tail controls allow semi-conformal carriage [2] on planes that are not as big as the MiG-31.

Mid-body strakes enhance lift [2] hence increases range. 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" (160220 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 Long-Range Air-to-Air Missile). R-37M’s range exceeds 300km, and it is capable of hypersonic speed (~Mach 6) in the final stage of its flight. [6] It will be carried by the modernized MiG-31BM interceptors and Su-35S and Su-57 multirole fighters. [7] It is not known whether the long range air-to-air missile for the Su-57, designated as Izdeliye 810, is a derivative of the R-37M.[ citation needed ]

The missile can attack targets at altitudes of 15–25,000 meters, guided semi-actively or actively through the Agat 9B-1388 system. [8]

Mikoyan MiG-31 Interceptor aircraft

The Mikoyan MiG-31 is a supersonic interceptor aircraft that was developed for use by the Soviet Air Forces. The aircraft was designed by the Mikoyan design bureau as a replacement for the earlier MiG-25 "Foxbat"; the MiG-31 is based on and shares design elements with the MiG-25. The MiG-31 is among the fastest combat jets in the world. It continues to be operated by the Russian Air Force and the Kazakhstan Air Force following the end of the Cold War and the collapse of the Soviet Union in 1991. The Russian Defence Ministry expects the MiG-31 to remain in service until 2030 or beyond and was confirmed in 2020 when an announcement was made to extend the service lifetime from 2,500 to 3,500 hours on the existing airframes.

RSD-10 Pioneer Intermediate-range ballistic missile

The RSD-10 Pioneer was an intermediate-range ballistic missile with a nuclear warhead, deployed by the Soviet Union from 1976 to 1988. It carried GRAU designation 15Ж45 (15Zh45). Its NATO reporting name was SS-20 Saber.

R-77 Medium-range, active radar homing air-to-air BVR missile

The Vympel NPO R-77 missile is a Russian active radar homing beyond-visual-range air-to-air missile. It is also known by its export designation RVV-AE. It is the Russian counterpart to the American AIM-120 AMRAAM missile.

Kh-55 Family of air-launched cruise missiles

The Kh-55 is a Soviet/Russian subsonic air-launched cruise missile, designed by MKB Raduga. It has a range of up to 2,500 km (1,350 nmi) and can carry nuclear warheads. Kh-55 is launched exclusively from bomber aircraft and has spawned a number of conventionally armed variants mainly for tactical use, such as the Kh-65SE and Kh-SD, but only the Kh-101 and Kh-555 appear to have made it into service. Contrary to popular belief, the Kh-55 was not the basis of the submarine- and ground-launched S-10 Granat or RK-55 Relief designed by NPO Novator. The RK-55 is very similar to the air-launched Kh-55 but the Kh-55 has a drop-down turbofan engine and was designed by MKB Raduga. Both have formed the basis of post-Cold-War missiles, in particular the Sizzler which has a supersonic approach phase.

The Kh-22 is a large, long-range anti-ship missile developed by MKB Raduga in the Soviet Union. It was intended for use against US Navy aircraft carriers and carrier battle groups, with either a conventional or nuclear warhead.

Novator KS-172 Long range air-to-air missile

The Novator KS-172 is a Russian air-to-air missile designed as an "AWACS killer" at ranges up to 400 km. The missile has had various names during its history, including K-100, Izdeliye 172, AAM-L (RVV-L), KS–172, KS-1, 172S-1 and R-172. The airframe appears to have been derived from the 9K37 Buk surface-to-air missile (SAM) but development stalled in the mid-1990s for lack of funds. It appears to have restarted in 2004 after a deal with India, who wants to produce the missile in India for their Su-30MKI fighters. It is the heaviest air-to-air missile ever produced.

P-270 Moskit Anti-ship missile

The P-270 Moskit is a Soviet supersonic ramjet powered anti-ship cruise missile. Its GRAU designation is 3M80, air launched variant is the Kh-41 and its NATO reporting name is SS-N-22 Sunburn. The missile system was designed by the Raduga Design Bureau during the 1970s as a follow up to the P-120 Malakhit. The Moskit was originally designed to be ship-launched, but variants have been adapted to be launched from land, underwater (submarines) and air, as well as on the Lun-class ekranoplan. The missile can carry conventional and nuclear warheads. The exact classification of the missile is unknown, with varying types reported. This uncertainty is due to the secrecy surrounding an active military weapon. The missile has been purchased and exported to the People's Liberation Army Navy (China) and Indian Navy (India).

The Kh-29 is a Soviet air-to-surface missile with a range of 10–30 km. It has a large warhead of 320 kg, has a choice of laser, infrared, active radar or TV guidance, and is typically carried by tactical aircraft such as the Su-24, Su-30, MiG-29K as well as the "T/TM" models of the Su-25, giving that craft an expanded standoff capability.

NPO Novator is a Russian company that designs long-range anti-aircraft missiles. It was established in 1947 as OKB-8 in Sverdlovsk, became independent in 1991, and then became part of the Almaz-Antey conglomerate. It is perhaps best known for designing the 9M82 and 9M83 missiles of the S-300V SAM system.

Kh-28 air-launched anti-radiation missile

The Kh-28 was the first Soviet anti-radiation missile for tactical aircraft. It entered production in 1973 and is still carried on some Sukhoi Su-22s in developing countries but is no longer in Russian service. Use of the Kh-28 was restricted by its weight, limited seeker head, bulk and fuelling requirements, and it was superseded by the smaller, solid-fuel Kh-58 in the early 1980s.

Kh-38 Tactical air-to-surface missile

The Kh-38/Kh-38M is a family of air-to-surface missiles meant to succeed the Kh-25 family of missiles.

The Mikoyan PAK DP is a Russian programme to develop a stealth interceptor aircraft/heavy fighter under development by Mikoyan to replace the Mikoyan MiG-31 in the Russian Air Force in mid-2020s or mid-2030s. It is often referenced as Mikoyan MiG 41, because its project code is izd.41, but its official designation has never been given, as Russian planes only get their official designation when they are about to enter service. According to the Russian defence analyst Vasily Kashin, the MiG-41 would be considered as a 5++ or 6th generation project.
