Fourth Yasen nuclear submarine to join ranks of Russian Navy

The fourth multirole nuclear submarine of the upgraded Project 885M (code name: Yasen) will be laid down at the Sevmash shipyard (Severodvinsk) on July 19, a source in the shipbuilding industry told Interfax-AVN on Thursday. "This will already be the fourth consecutive nuclear submarine codenamed Yasen and the third consecutive upgraded ship of Project 885M to be laid down at Sevmash. It will be laid down along with the fifth Borei, Knyaz Oleg," the source said.He recalled that the Project 885 Yasen head multirole fourth-generation nuclear submarine named Severodvinsk designed by the St. Petersburg-based Malakhit Design Bureau was floated on June 15, 2010. Sevmash is to build seven Yasen submarines for the Navy before 2020, six of them under the upgraded Project 885M, starting from Kazan which was laid down in June 2009.

The Novosibirsk nuclear submarine was laid down on July 26, 2013. According to open sources, the Malakhit-designed Yasen submarines are double-hulled single-shaft ships. For the first time in the history of domestic ship-building torpedo tubes were placed not in the submarine's bow but behind the control post section, thus making it possible to put a hydroacoustic antenna in the fore end. Eight vertical launchers are used for missile weapons. The armament complex includes supersonic cruise missiles, universal deepwater self-propelled torpedoes and mines.Yasens are fitted with a completely new nuclear propulsion unit. The ships' displacement is estimated at 9,500 tones, length 120 meters, test depth 600 meters. Full speed (submerged): 31 knots approximately 57 kilometers per hour). Crew: 85 members.Fifth Borei-class nuclear submarine to be constructed for Russian Navy.

The nuclear-powered ballistic missile submarine Knyaz Oleg, the fifth to be built under Project 955A Borei, designed by Rubin Central Design Bureau, will be laid down at the Sevmash Shipyard on July 19, a source in the shipbuilding industry told Interfax-AVN on Thursday. "The fifth Borei will be called Knyaz Oleg. It will be laid down at the Sevmash on July 19," the source said.
He also said that the Knyaz Oleg will become the second nuclear submarine to be built under the improved project 955-A. The Borei project's head nuclear submarine, Yuriy Dolgorukiy, raised its flag on January 10, 2013; the first one serially-produced - Aleksandr Nevsky - was handed over to the Navy on December 23, 2013. The third Borei, Vladimir Monomakh, is undergoing tests before entering service in the Navy this year. A solid hull has been built for the fourth ship - an upgraded Project 955-A, Borei-A, new-generation nuclear submarine Knyaz Vladimir.The Project 955 Borei nuclear submarines have the following characteristics: displacement 24,000 tons (submerged), length 170 meters, width 13.5 meters, draught 10 meters, speed 29 knots, armament: 16 Bulava ICBMs (intercontinental ballistic missiles), torpedoes and torpedo missiles in six 533-millimeter torpedo tubes.
