Golf-class submarine

Project 629 (Russian: проект–629, Projekt-629), also known by the NATO reporting name Golf, was a class of diesel-electric ballistic missile submarines that served in the Soviet Navy. All boats of this class had left Soviet service by 1990, and have since been disposed of. According to some sources, at least one Golf-class submarine was operated by China, to test new submarine-launched ballistic missiles (SLBMs).
