The KSShch (Russian: Корабельный снаряд «Щука» (КСЩ);[1] tr.
:Korabelny snaryad Shchuka (KSShch); English: Anti-Ship Missile "Pike") was a Soviet anti-ship cruise missile design that carried a nuclear warhead.
It was tested in 1953–1954 on the destroyer Bedovyy (Kildin-class) and entered service in 1955, being deployed on Kildin- and Krupnyy (later converted to Kanin)-class ships.
It was fired from a heavy rail launcher SM-59, with an armoured hangar.
As those ships were retrofitted and modernized between 1966 and 1977, the missiles were removed (in favor of the SS-N-2 on the Kildin class and an anti-aircraft/anti-submarine weapons suite on the Kanin class).
