Description
The KSShch, designated 4K32 and P-1 Strela, is a Soviet anti-ship cruise missile. Tested between 1953 and 1954 on the destroyer Bedovyy, the system entered service in 1955. It was assigned the NATO reporting name SS-N-1 Scrubber.
The missile is powered by a liquid-fuel rocket and employs inertial guidance. Warhead options include high-explosive or nuclear variants. The system is fired from an SM-59 heavy rail launcher, which is protected by an armored hangar.
The Soviet Navy was the sole operator of the KSShch. Deployment was concentrated on Kildin-class and Krupnyy-class destroyers, with additional testing conducted aboard the Project 68ER cruiser Admiral Nakhimov. Between 1966 and 1977, the missiles were removed as the carrier vessels underwent modernization. On Kildin-class ships, the KSShch was replaced by the SS-N-2, while Krupnyy-class ships were converted to the Kanin class and refitted with anti-aircraft and anti-submarine weapon suites. The system was withdrawn from service by 1977.
