The Soviet Union's Project 949 (Granit) and Project
949A (Antey) submarines are known in the West by their
NATO reporting names: the Oscar-I and Oscar-II classes
respectively.
Oscars are comparable in size to the Ohio-class submarines of the United States Navy:
Oscars displace less when surfaced but more when submerged; they are shorter in length but broader in beam.
Two Oscar-I submarines were built at Severodvinsk
and assigned to the Soviet Northern Fleet:
- K-525, Minsky Komsomolets, laid down 1978, commissioned 1980, renamed Arkhangelsk in 1991
- K-206, Murmansk, was commissioned in 1981
Ten Oscar-II submarines were built at Severodvinsk.
Six were assigned to the Soviet Northern Fleet:
- Soviet submarine K-148, Krasnodar, commissioned 1986
- Soviet submarine K-119, Voronezh, commissioned 1988
- Soviet submarine K-410, Smolensk, commissioned 1990
- Soviet submarine K-266, Orel, formerly Severodvinsk, commissioned 1992
- Soviet submarine K-186, Omsk, launched May 8, 1993, commissioned October 27, 1993
- Soviet submarine K-141, Kursk, laid down 1992, launched 1994, commissioned December 1994, lost August 12, 2000
Four were assigned to the Soviet Pacific Fleet:
