Yankee-class submarine

The Soviet Navy's Project 667A Navaga (navaga) and Project 667AU Nalim (burbot) (NATO reporting name: Yankee), were a family of nuclear-powered ballistic missile submarines built in the Soviet Union. In total, 34 units were built, from 1964 to 1974: 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.
