The Kh-25/Kh-25M (Russian : Х-25; NATO:AS-10 'Karen') is a family of Soviet lightweight air-to-ground missiles with a modular range of guidance systems and a range of 10 km. [1] The anti-radar variant (Kh-25MP) is known to NATO as the AS-12 'Kegler ' and has a range up to 40 km. [2] Designed by Zvezda-Strela, the Kh-25 is derived from the laser-guided version of the Kh-23 Grom (AS-7 'Kerry'). It has now been succeeded by the Kh-38 family, but the Kh-25 remains in widespread use.

Development

Based on an air-to-air missile, the beam-riding Kh-66 had been the Soviet Union's first air-to-ground missile for tactical aircraft, entering service in 1968. [6] However it proved difficult to use in practice as the launch aircraft had to dive towards the target. A version with radio-command guidance, the Kh-23, was first tested in 1968 but problems with the guidance system meant that it would not enter service for another five years. [7] So in 1971 work began on a version with a semi-active laser seeker, which became the Kh-25. [6] This was initially known in the West as the Kh-23L. [8] State testing began on 24 November 1974, and the Kh-25 entered production in 1975. [6]

Work began on an anti-radar missile derived from the Kh-66 [5] in 1972, using a passive radar seeker and SUR-73 autopilot. [6] The long-range Kh-31 anti-radar missile came out of the same project. [6] The Kh-27 began state testing on a MiG-27 on 8 August 1975 [6] but did not enter service until 2 September 1980. [6] It was assigned the NATO reporting name AS-12 'Kegler' and in effect it replaced the much heavier Kh-28 (AS-9 'Kyle'). [5]

In 1973 Victor Bugaiskii was appointed head engineer of the bureau and he started work on combining the Kh-23M, Kh-25 and Kh-27 into a single modular system to reduce costs and improve tactical flexibility. [6] This was completed by the end of 1978, [6] resulting in the Kh-25MP (anti-radar), Kh-25ML (laser-guided) and Kh-25MR (radio-guided) family. NATO continued to refer to these as the AS-12 and AS-10 respectively, even though they could now be switched by a simple change of seeker head.

Design

The Kh-25 is very similar to the later version of the Kh-23 Grom, with cruciform canards and fins.

The Kh-25MP has two versions of its homing head, 1VP and 2VP, sensitive to different frequencies. [2]

Combat history

The original Kh-25 entered service with the Soviet Air Force between 1973-5, equipping the MiG-23, MiG-27 and Su-17M. [4] Since then it has been cleared for use on the MiG-21, MiG-29, Sukhoi Su-17/20/22 family, Sukhoi Su-24, Su-25 and Su-27. [4] It can also be carried by attack helicopters such as the Kamov Ka-50.

The Kh-25MP can be fitted to the MiG-23/27, Su-17/22, Su-24 and Su-25. [5]

Soviet war in Afghanistan

Starting in April 1986, during the second Battle of Zhawar, Kh-25MLs were used by Soviet Su-25 Frogfoots from the 378th OshAP (Independent Shturmovik Aviation Regiment) to attack Mujahideen cave entrances used as shelters and weapons storage facilities. Attacks were carried out from up to 4.5 nm (8 km). [9]

Iraqi invasion of Kuwait

During the Iraqi invasion of Kuwait, on August 2, 1990 an Iraqi Air Force Sukhoi Su-22 from the No.109 Squadron (based at as-Shoibiyah AB) fired a single Kh-25MP anti-radar variant against a Kuwaiti MIM-23B I-HAWK SAM site at Bubiyan Island that had earlier downed another Su-22 from the same unit and a MiG-23BN from the 49th Squadron. This forced a radar shutdown on the HAWK. The HAWK battery (which was operated by some American contractors) was later captured by Iraqi special forces and found out to be in automatic mode of operation, after the contractors fled. [10]

Chechen Wars

Russian Air Force Su-25s employed the Kh-25 in its two Chechen campaigns for attacks on fixed positions, such as mortars and bunkers. However, their usage wasn't extensive in relation to those of unguided bombs and rockets. The use of precision-guided munitions allowed air support in areas too dangerous for attack helicopters. Their use was not widespread in the First War as was in the Second, mainly due to differences in weather conditions and, probably, the need to keep a strategic reserve of stockpiles shortly after the fall of the USSR. [11]

Russia intervention in Syria

Laser-guided Kh-25s were employed by Su-24 sweep wing strike aircraft against anti-Assad rebels in Syria.[ citation needed ]

Variants

NATO refers to all of the Kh-25 family as AS-10 'Karen' apart from the anti-radar variants. An "M" designation stands for "Modulnaya" – modular (seeker head).

Training rounds have "U" designations, so, e.g., for the Kh-25ML there is:

Mikoyan MiG-27 Series of attack aircraft

The Mikoyan MiG-27 is a variable-sweep ground-attack aircraft, originally built by the Mikoyan-Gurevich design bureau in the Soviet Union and later licence-produced in India by Hindustan Aeronautics as the Bahadur ("Valiant"). It is based on the Mikoyan-Gurevich MiG-23 fighter aircraft, but optimised for air-to-ground attack. Unlike the MiG-23, the MiG-27 did not have widespread use outside Russia, as most countries opted for the Mikoyan-Gurevich MiG-23BN and Sukhoi Su-22 instead. It remains in service only with the Kazakh Air Forces in the ground attack role. All Russian, Indian and Ukrainian MiG-27s have been retired.

Sukhoi Su-25 Family of Russian attack aircraft

The first prototype made its maiden flight on 22 February 1975. After testing, the aircraft went into series production in 1978 at Tbilisi in the Georgian Soviet Socialist Republic.

Sukhoi Su-24 Family of strike and reconnaissance aircraft

The Sukhoi Su-24 is a supersonic, all-weather attack aircraft developed in the Soviet Union. The aircraft has a variable-sweep wing, twin-engines and a side-by-side seating arrangement for its crew of two. It was the first of the USSR's aircraft to carry an integrated digital navigation/attack system. It remains in service with the Russian Air Force, Syrian Air Force, Ukrainian Air Force, Azerbaijan Air Force, Iraqi Air Force and various air forces to which it was exported.

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.

Sukhoi Su-17 Soviet variable-sweep wing fighter-bomber developed from the Sukhoi Su-7

The Sukhoi Su-17 is a variable-sweep wing fighter-bomber developed for the Soviet military. Its NATO reporting name is "Fitter". Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service. Two subsequent Sukhoi aircraft, the Su-20 and Su-22, have usually been regarded as variants of the Su-17.

The Kaliningrad K-8 (R-8) was a medium-range air-to-air missile developed by the Soviet Union for interceptor aircraft use.

Kh-15 air-to-surface/antiship missile

The Raduga Kh-15 or RKV-15 is a Russian hypersonic aero-ballistic missile carried by the Tupolev Tu-22M and other bombers. Originally a standoff nuclear weapon similar to the U.S. Air Force's AGM-69 SRAM, versions with conventional warheads have been developed.

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.

Air-to-surface missile

An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed.

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.

Kh-31 Medium-range air-to-surface missile

The Kh-31 is a Russian air-to-surface missile carried by aircraft such as the MiG-29 or Su-27. It is capable of Mach 3.5 and was the first supersonic anti-ship missile that could be launched by tactical aircraft.

It is designed to attack vessels up to 5,000 tonnes.

Sukhoi Su-30MKM Malaysian version of the Su-30MK multirole combat aircraft

The Sukhoi Su-30MKM is a supermaneuverable fighter of the Royal Malaysian Air Force. It is a variant of the Su-30 series fighters, with many significant improvements over the original Su-30MK export version. The Su-30MKM was developed by the Sukhoi Design Bureau and is based on the Su-30MKI of the Indian Air Force. Both aircraft have common airframe, thrust vectoring engines and digital fly-by-wire system, however the MKM version differs from the MKI mainly in the composition of the onboard avionics. It can carry up to 8,000 kg (17,637 lb) payload over a 1,296 km un-refueled combat radius.

Kh-23 Grom Tactical air-to-surface missile

The Zvezda Kh-66 and Kh-23 Grom are a family of early Soviet tactical air-to-surface missiles with a range of 10 km. They were intended for use against small ground or naval targets. The Kh-66 was effectively a heavy-warhead, beam-riding version of the K-8 air-to-air missile rushed into service in Vietnam in 1968. The Kh-23 was an improved Kh-66 with command-guidance, similar to the AGM-12 Bullpup.

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.
