Oscar-class submarine
The Oscar class, Soviet designations Project 949 Granit and Project 949A Antey (NATO reporting names Oscar I and Oscar II respectively), are a series of nuclear-powered cruise missile submarines designed in the Soviet Union for the Soviet Navy. First built in the 1970s, six remain in service with the Russian Navy. Two other vessels were slated to be modernized since at least 2017 as Project 949AM, to extend their service life and increase combat capabilities but it is unclear whether work continues as of 2023.

The Project 949 submarines were the largest cruise missile submarines in service until some 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 Soviet Typhoon-class, Russian Borei-class and American Ohio-class ballistic missile submarines are larger.
