Two November class and one Echo I class subs.
The Project 627 (NATO - November) class submarine was the Soviet Union's first class of nuclear-powered submarines. Built between 1952-1958.
The Soviet Echo I class (Project 659 class) were completed at Komsomolsk in the Soviet far east in 1960 to 1962. The Echo I class were classed as SSGNs armed with six launchers for the P-5 Pyatyorka (SS-N-3C, "Shaddock-B") cruise missile. The Echo I class had to operate in a strategic rather than attack role because of the lack of fire control and guidance radars.
