Submerged Severodvinsk Sub Test Fires Cruise Missile

Russia's newest attack submarine, the Yasen class Severodvinsk, successfully fired a cruise missile while submerged, a source in the United Shipbuilding Corporation told RIA Novosti on Wednesday.

The test launch was the second during the current manufacturer's sea trials in the White Sea. On Monday, the sub fired a cruise missile from a surfaced position.

"The multipurpose nuclear-powered submarine Severodvinsk fired a supersonic cruise missile at a land target while submerged during sea trials in the White Sea. The target was successfully destroyed," the source said.

The Severodvinsk, laid down in 1993, is one of eight Yasen class boats ordered by the Russian Navy. The second sub of the series, the Kazan, is being built under the updated Project 885M Yasen-M.

The Severodvinsk has a submerged displacement of 13,800 tons, length of 119 meters, speed of 31 knots, and can dive to 600 meters. It has a crew of 90 including 32 officers.

Its main armament consists of 3M55 Oniks (SS-N-26) and 3M54 (SS-N-27) Kalibr cruise missiles, self-guided torpedoes and mines.
