Information About

Oscar Class Submarine




The Soviet Union ’s Project 949 (Granit) and Project 949A (Antey) Submarine s are known in the West by their NATO Reporting Name s: 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.

Two Oscar-I submarines were built at Severodvinsk and assigned to the Soviet Northern Fleet :

Ten Oscar-II submarines were built at Severodvinsk .
Six were assigned to the Soviet Northern Fleet :

Four were assigned to the Soviet Pacific Fleet :


GENERAL CHARACTERISTICS


  • Displacement when surfaced: 13,400 tons (Oscar-I), 14,700 tons maximum (Oscar-II)

  • Displacement when submerged: 20,540 tons (Oscar-I), 24,000 tons (Oscar-II)

  • Length: 144 meters (Oscar-I), 155 meters (Oscar-II)

  • Beam: 18.2 meters

  • Draft: 9 meters (Oscar-I) 9.2 meters (Oscar-II)

  • Max depth: Oscar-I - 400 meters regular, 450 critical. Oscar-II - 500 meters regular, 600 critical.

  • Compartments: 10

  • Complement: 48 officers, 68 men (Oscar-I) or 59 men (Oscar-II)

  • Reactor: Two OK-650b pressurised water reactors generating 190 MW each.

  • Propulsion: two shafts, each 49,000 hp

  • Speed (submerged): 30 knots (Oscar-I), 28 knots (Oscar-II)

  • Strategic armament: 24 Granit SS-N-19 Missile s 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).

  • Defensive armament: four 533-mm and two 650-mm bow torpedo tubes


Like other Soviet submarines, the Oscar not only has a bridge open to the elements on top of the sail but, for use in inclement weather, an enclosed bridge forward of this station in the sail.

A distinguishing mark is a slight bulge at the top of the fin. A large door on either side of the fin reaches this bulge. These are wider at the top than on the bottom, and are hinged on the bottom. It is reported in the Federation Of American Scientists ' web page {Link without Title} that this submarine carries an emergency crew escape capsule, and as there is no more likely visible feature, these doors apparently cover it.
