Project 949 (Granit) and Project 949A (Antey) are Soviet Navy/Russian Navy cruise missile submarines (NATO reporting names: Oscar I and Oscar II respectively).

Project 949 submarines were the largest cruise missile submarines in service, until the Ohio-class ballistic missile submarines were converted to carry cruise missiles in 2007. They are the fourth largest class of submarines in displacement and length. Only the Typhoon-class Soviet/Russian submarines, the American Ohio-class ballistic missile submarines and the Russian Borei-class submarines are larger.


The first submarine of Project 949 was laid down in the mid-1970s and was commissioned in 1980. In 1982 an updated and larger version (Project 949A) replaced the earlier version. In total thirteen submarines were constructed. The Oscar class was designed to attack NATO carrier battle groups using long-range SS-N-19 "Shipwreck" anti-ship missiles and targeting data provided by the EORSAT satellite system (via the submarine's "Punch Bowl" antenna).[6][7][8] In the financial problems that followed the fall of the Soviet Union the Oscar class was prioritized by the Russian Navy and when many older submarine classes were retired the Oscar class remained active in both the Northern and Pacific Fleets. As of 2011, five submarines are currently active with several more in reserve or waiting for repairs.
