Projekt 945 Barrakuda

The design offices Lazurite, malachite and Rubin then began with three developments. While Lazurite Rubin and a titanium hull preferring preferred malachite a steel hull, but only because of the cost. Complicated welding of titanium hulls and are very expensive to maintain. Lazurite finally made the project 945 (NATO: Sierra I) before 1978 and got Award keel laying of the two units and Rubin got 1980 for the boot order. At about the same time was to build the unity of the one project 685: Worden started the hapless K-278 Komsomolets (NATO "Mike"). The project was given the NATO reporting name "Sierra I".

Units

B-239

On 25 July 1977, the B-239 first unit of the project as 945 BAPL ( Bolshaya nuclear Well Podwodnaja Lodka - Large nuclear submarine) was added to the fleet list of the Navy and the command was transferred EW Gurbew. On 20 July 1979 welded shipbuilders in Bauhallen of Krasnoye Sormovo in Gorky , the first sections of the keel laying of the B-239. The assembly of the first fuselage lasted because of the enormous cost nearly four years, until 29 Was completed in July 1982 with the rolling out of the construction hall of the launch. For final outfitting and testing of B-239 was on barges up the Volga to Severodvinsk , where she was finally in the White Sea ran through the sea trial.
On 29 June 1984 B-239 was finally made ​​to serve the Navy and the Northern Fleet passed. In 1992 the boat in K-239 and was reclassified in the 6th April In 1993 the name "Karp" (carp ). have been modernized from July to December 1994 in the shipyard in Severodvinsk Swesdotschka among other weapons systems and sensors. On 30 May 1998 K-239 Karp was launched in the wake of the first major repair in Severodvinsk. In the course of growing money problems of the Russian forces and the enormous cost, the boat was preserved and hung up. Whether K-239 will return to the service is questionable.

B-276

The second unit of the project 945, B-276 (or K-276) was deposited on 9th Date February 1982 in the fleet list and 21 April 1984 Krasnoye Sormovo Keel-laying. The command had SW Kulakov. On 26 July 1986, the launch occurred on 30 December 1987 B-276 was lodged with the Northern Fleet in service. Together with her ​​sister ship, she was in the Ura Bay stationed.
On 11 February 1992 pushed B-276 in the Barents Sea with the U.S. submarine USS Baton Rouge together. The collision severely deformed the tower and the submarine had to return to the base. Of 28 March to 29 June saw the repair at the shipyard Nerpa instead. On 6 April 1993, the ship received the name of "Krab". On 15 November 1996 was renamed the boat "Kostroma". In 2000 the ship to the main repair in the shipyard was Nerpa launched. After a major upgrade B-276 was Kostroma 2005 reincorporated into the fight stock.

Project 945AB

The Project 945A was well proven in combat patrols and the boats were never prosecuted. Lazurite put on a further modification, the project 945AB, which should eventually be included in the series production. The keel for the first boat, K-123, was in March 1990 at Krasnoye Sormovo down. Shortly thereafter, the funds for the project have been removed since the project was now gone into 971U series. What happened to K-123, is unclear, but it is quite possible that the body still rests in the construction hall.
