The S-2 Sopka coastal defense system (Russian GRAU code 4K87) (NATO code: SSC-2b Samlet) was a conventionally armed variant which attached a SPRD-15 jet assisted rocket to launch the missile from fixed launchers. After attaining sufficient velocity, the AS-1 turbojet would carry the missile to the target. The system was designed for land based attacks on sea targets and widely deployed in eastern bloc countries such as Poland and East Germany during the Cold War. One Sopka regiment was stationed in Cuba as part of Operation Anadyr. The Samlet was deployed to Alexandria and fired at Israeli ships during the Yom Kippur War. The Samlets saw long service despite their obsolescence and were finally retired from the Soviet arsenal in 1980.
