Their range exceeds 9 thousand km. The submarine is 170 meters long, the beam is 13.5 meters, and the draft is 10m. The Borei class, alternate transliteration Borey, Russian designation Project 955 Borei and Project 955A Borei-A, (Russian: Борей, lit. [12][13] Yuriy Dolgorukiy was the first Russian strategic missile submarine to be launched in seventeen years since the end of the Cold War. Este contratiempo provocó que el submarino debiera ser reformado para alojar el nuevo misil, y el proyecto fue renombrado como Proyecto 955 Borei. [23] The plan was then postponed to mid-summer 2011 due to ice conditions in the White Sea. The fourth Borei Class ship, Knyaz Vladimir, was laid down in July 2012. [34], The Borei submarines are approximately 170 metres (560 ft) long, 13 metres (43 ft) in diameter, and have a maximum submerged speed of at least 46 kilometres per hour (25 kn; 29 mph). [23] The plan was then postponed to mid-summer 2011 due to ice conditions in the White Sea. A salvo from SSBN can destroy dozens of targets. [42], The Project 955B was expected to feature a new water jet propulsion system, an upgraded hull, and new noise reduction technology. Aunque en un principio los submarinos consecutivos al Yuri Dolgoruki serían más grandes y portarían 16 misiles Bulava, en vez de los 12 misiles que portaría el Yuri Dolgoruki,[7]​ según el informe START de 2007 todos los submarinos, incluyendo al Yuri Dolgoruki, portarán 16 misiles. The planned contingent of eight strategic submarines was expected to be commissioned within the next decade, with five Project 955 planned for purchase through 2015.[14]. According to Covert Shores, the Russian Navy launched its 4th Borei Class ballistic missile submarine (SSBN) in November 2017. [30][31], On 17 November 2017, the fourth Borei-class submarine and the first of the improved Project 955A, the Knyaz Vladimir was moved out of the construction hall at the SEVMASH shipyard. 949ASSN Clase Akula Pr. The submarine needed to be redesigned to accommodate the new missile, and the design name was changed to Project 955. By July 2009, it had yet to be armed with Bulava missiles and was therefore not fully operational, although ready for sea trials on 24 October 2008. Its construction requires 17 thousand tons of metal which is 50 % more than the Eiffel Tower. Tras los fracasos de las pruebas realizadas con este nuevo misil, la producción del misil R-39M Bark se canceló en 1998 y un nuevo misil, el Bulava (SS-NX-30), empezó a proyectarse. [48], The contract for five modified 955A submarines was delayed several times due to price dispute between the Russian Defence Ministry and the United Shipbuilding Corporation. [citation needed], Borei class includes a compact and integrated hydrodynamically efficient hull for reduced broadband noise and the first ever use of pump-jet propulsion on a Russian nuclear submarine. [28][29] After long delays finally the lead vessel, Yuriy Dolgorukiy, joined the Russian Navy on 10 January 2013. Americans have been using pump-jet propulsions on Seawolf-class nuclear submarines since the 1990s. It has been reported that the arrival of the Borei class will enable the Russian Navy to resume strategic patrols in southern latitudes that have not seen a Russian missile submarine for 20 years. It was inked by the chair of the acceptance commission of the Navy, Captain 1st rank Alexey Poteshkin, Sevmash Shipyard CEO Mikhail Budnichenko, Rubin Chief Designer Sergey Sukhanov and SSBN Commander Captain 1st rank Vladislav Druzhin. The design incorporates many Western design influences with new tail configuration and sail which resemble US Navy submarines. The first design work on the project started in the mid-1980s and the construction of the first vessel started in 1996. [52][53] According to a 2018 report, Russia's State Armament Programme for 2018–2027 includes construction of two more Borei-A submarines by 2028. It is the first class of submarines developed by Russia since the soviet era. Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy.They are the world's third-largest submarines, behind the Russian Navy's Soviet-designed 48,000-ton Typhoon … The missile is 12.1m long and has a diameter of 2.1m (including the launch container). As for the Borei-A submarines, the main difference of these submarines from the original version is improved performance. [46] Although first reported to carry 20 Bulava SLBMs, the 955A will be armed with 16 SLBMs with 6-10[47][4] nuclear warheads atop each, just like the project 955 submarines. [21] On 9 November 2010 Yuriy Dolgorukiy passed all sea trials directed to new equipment and systems. 945AArmada de Rusia, Víktor Litovkin, redactor de la Revista Militar Independiente, misil balístico intercontinental para submarinos,, Details emerge of Russia's latest cruise missiles, Los submarinos nucleares clase Borei incrementan el potencial disuasorio de Rusia, «La Armada rusa anuncia la construcción del último submarino Boréi», «Источник: две АПЛ "Борей-А" заложат в день 75-летия Победы», El submarino Yuri Dolgoruki portará 16 misiles Bulava, Comunicado de que el primer submarino se botará en abril de 2007, Comunicado (en ruso) de que el primer submarino no estará listo hasta 2007, Información del Proyecto 935 / Proyecto 955,, Licencia Creative Commons Atribución Compartir Igual 3.0, • 16 misiles balísticos intercontinentales Bulava, • 1 reactor nuclear de agua a presión ОК-650В. It has been reported that the arrival of the Borei class will enable the Russian Navy to resume strategic patrols in southern latitudes that have not seen a Russian missile submarine for 20 years. The ship was formally inducted into the Russian Navy in January 2013. The…, The Russian Kilo-class submarine first entered service in the early 1980s.

Alexander Nevsky (K-550), the second submarine, was laid down in March 2004 and launched in December 2010. The Bulava missile warhead is a diversion type – MIRV. The acoustic signature of Borei is significantly stealthier than that of the previous generations of Russian SSBNs, but it have been reported that their hydraulic pumps become noisier after a relatively short period of operation, reducing the stealth capabilities of the submarine. Los submarinos de este tipo reemplazarán a los submarinos Proyecto 667BDR Kalmar (Delta III) y submarinos Proyecto 941 Akula (Typhoon). Thanks to its compact size, the ship can move in shallow water. SSBN Delta IV Pr. [35] Smaller than the Typhoon class, the Boreis were initially reported to carry 12 missiles but are able to carry four more due to the decrease in mass of the 36-ton Bulava SLBM (a modified version of the Topol-M ICBM) over the originally proposed R-39UTTH Bark. [3]​[4]​ Nueva información disponible revela que tienen un menor desplazamiento que los submarinos Schuka o Akula, y que su inmersión y maniobrabilidad fueron ampliamente mejorados, debido a un nuevo y moderno reactor nuclear.[4]​.
