Project 629 (Russian: проект–629, proyekt-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 left Soviet service by 1990, and have since been disposed of.^[2]^[3]^[4] According to some sources, at least one Golf-class submarine was operated by China, to test new submarine-launched ballistic missiles (SLBMs).^[1]
