The Yankee class, Soviet designations Project 667A Navaga (navaga) and Project 667AU Nalim (burbot) for the basic Yankee-I, were a family of nuclear-powered ballistic missile submarines built in the Soviet Union for the Soviet Navy. In total, 34 units were built: 24 in Severodvinsk for the Northern Fleet and the remaining 10 in Komsomolsk-on-Amur for the Pacific Fleet. Two Northern Fleet units were later transferred to the Pacific.
The Yankee-class were subject to a wide variety of modifications; these ships have a different designation to the original model.
