The Raduga Kh-26 KSR-5 (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', built to be carried by the less capable Tu-16.
The Raduga KSR-5 was developed in variants to be deployed as a land attack missile and an anti-ship missile. The missile was designed to be fitted with either a conventional or nuclear warhead.
The Raduga KSR-5 was deployed aboard such Soviet aircraft as the Tupolev Tu-16 'Badger' in Tu-16K-26, Tu-16KSR-2-5, and Tu-16KSR-2-5-11 variants, as well as the Tu-22M Backfire.Post 1991 with the retirement of the Badger, the KSR-5 warstock was converted into supersonic targets.
