The KSR-5, also designated as the Kh-26 (NATO reporting name AS-6 Kingfish) was a long-range, air-launched cruise missile and anti-ship missile developed by the Soviet Union. It was essentially a scaled down version of the Kh-22 'Kitchen', primarily carried by the Tupolev Tu-16 bomber.

Background

In the early 1960s the development of new nuclear-capable strategic bombers came into a virtual halt in the Soviet Union, with the focus being shifted on nuclear ballistic missiles and developing cruise missiles for existing aircraft. Developments in jet fighters and surface-to-air missiles during the 1950s made the use of nuclear free-fall bombs impractical against densely protected targets while missiles gave bombers the possibility of striking targets beyond the range of enemy anti-aircraft weapons.

Description

Developed in the late 1960s, the KRS-5 (also designated as the Kh-26) is an improved version of the Kh-22 missile, designed to be smaller, lighter and with a smaller radar signature. According to Janes, it was designed jointly by the Tupolev and Mikoyan Design Bureaus. It was developed as a conventional anti-ship missile and a nuclear cruise missile capable of striking ground targets. Originally designed to be carried on the Tu-22 "Blinder", it was primarily mounted on the Tu-16 "Badger", but it could also be mounted on Tu-22M "Backfire" and Tu-95M "Bear" aircraft as well.

The missile had a maximum range of and cruise speed of Mach 3 when released from high altitude and range and cruise speed of Mach 2 when launched at low altitude.

Variants

• Kh-26 − Nuclear variant with inertial guidance. Armed with a 350 kiloton warhead weighing about .
• Kh-26N − Active radar homing anti-ship variant, it could carry either a nuclear warhead or a conventional HE SAP warhead. The seeker had a lock-on range of .
• Kh-26MP − Anti-radiation variant with a passive radar seeker and a HE blast/fragmentation warhead for use against land-based or ship-mounted radars.
• KSR-5NM and KSR-5MV − Russian air-launched target variants designed by MKB Raduga. They were offered for export in 1993.

Operational history

The KSR-5 entered service in 1969, with later versions designed to be carried in the Tu-95 and Tu-95M being introduced in 1973 and 1976 respectively. In June 1991, it was estimated that the Soviet Union had 300 missiles carried on Badger-G bombers.

Following the dissolution of the Soviet Union, the remaining missiles were used by Russia and possibly Ukraine until 1994. With the retirement of the Tu-16, the nuclear versions of the KSR-2 and KSR-5 missiles were retired by 1993. In 1991, it was estimated Russia had about 100 missiles in its inventory, but most were converted into supersonic targets.

Operators

• − Most were converted for missile target practice
• − Passed on to successor states
