The AS-20 “Kayak” (Kh-35) is a short-range, air-launched, turbofan propelled, single warhead, air-to-surface cruise missile developed and manufactured by Russia.
The Zvezda-Strela OKB (now Tactical Missile Corporation) began developing the SS-N-25 “Switchblade” missile in 1983. It was originally intended as a surface-to-surface missile for ship and coastal launch, and an export replacement for the SS-N-2 “Styx” missiles. The ship-launched version is known as the SS-N-25 “Switchblade” (3M24 Uran) and the ground-launched coastal defense version as the SSC-6 “Stooge” (3K60 Bal). An air-launched version, the AS-20 “Kayak” (Kh-35), was added later.
Development of the air-launched AS-20 “Kayak” (Kh-35) began in 1987, and was first exhibited in 1992. The missile is similar in appearance to the U.S. RGM-84 “Harpoon,” with four triangular wings at mid-body, and four triangular moving control fins at the rear. It is 3.75 m in length, has a body diameter of 0.42 m, and has a launch weight of 480 kg. Midcourse guidance is provided by an inertial navigation system (INS), with an active radar in the terminal phase. It is powered by a solid propellant boost motor and a turbofan engine. The missile has a range of 130 km and carries a 145 kg high explosive semi-armor piercing warhead.
The AS-20 “Kayak” entered service 1995, and is deployed on MiG-29K “Fulcrum” carrier-borne aircraft, as well as Su-24 “Fencer,” Su-27 and Su-30 “Flanker,” Tu-95 “Bear,” and Tu-142M “Bear F” aircraft, and Kamov Ka-27, Ka-28, and Ka-50 helicopters. A modified version is also used as a Russian anti-ship missile target, so that missile defense systems can replicate attacks by missiles such as Exocet and Harpoon. The export version is known as the X-35.
In 1997, sources indicated that Russia had developed a new imaging infrared seeker for a variant of the air-launched AS-20, with the Russian designator Kh-37. It is expected that this variant will also be offered for export in ship- and ground-launched versions. The following year, a further improved variant of the AS-20 air-launched missile was reported to be in development, with a range of 250 to 300 km. This version may be offered with INS/GPS guidance for attacking land targets.(1)
