Yantar-2K (Russian: Янтарь meaning amber) was a type of Soviet reconnaissance satellite which supplemented and eventually replaced the Zenit spacecraft. It was the first satellite of the Yantar series and was managed by the Soviet military intelligence agency, the GRU. These satellites were in orbit for 30 days and photographed sites of interest using a film camera. Yantar-2K was proposed in 1967 and had its first test launch in May 1974. It was in military service from 1978 to 1983 and was given the name Feniks (Russian: Феникс), meaning phoenix.
