Russian Oscar II submarine in drydock

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 the largest attack subs by now, being slightly larger than Ohio-class submarines of the United States Navy, displacing less when surfaced but more when submerged, as they are shorter in length but broader in beam.

Carries 24 Granit SS-N-19 missiles in two banks of 12 tubes mounted outside the pressure hull. Six large doors, hinged on the outside, cover the tubes in pairs on either side of the sail (British: fin).
