Russian Submarine B-276 Kostroma
B-276 ''Kostroma'' is a Russian . She was launched in 1986, commissioned in 1987, and named K-276 ''Crab'' until 1992. ''Kostroma'' was built at Gorky and later towed to Severodvinsk for completion. She is part of the Russian Northern Fleet. On 11 February 1992, ''Kostroma'' - then still named K-276 ''Crab'' - while undergoing combat training in the Barents Sea, collided with USS ''Baton Rouge'' (some sources state it was K-239 ''Carp'' that collided with ). ''Baton Rouge'' was damaged (as was ''Crab'') and was eventually deactivated in 1993. K-276 damaged the cabin fencing and the fairing of the hydroacoustic complex (GAK). The renovation was completed by June of the same year and the submarine re-entered the 7th Submarine Division of the Northern Fleet. SSN-689 "Baton Rouge" was handed over for recycling two years later, having ceased to exist in 1997. On the K-276 wheelhouse, the crew drew the number "1", bordered with a star, as Soviet submariners did during the Great ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Severodvinsk
Severodvinsk ( rus, Северодвинск, p=sʲɪvʲɪrɐdˈvʲinsk) is a city in the north of Arkhangelsk Oblast, Russia, located in the delta of the Northern Dvina, west of Arkhangelsk, the administrative center of the oblast. As of the 2021 Census, the population was 157,213. Due to the presence of important military shipyards (specialising in submarines since the Soviet period), Severodvinsk is an access-restricted town for foreign citizens. A special permit is required. It was previously known as Sudostroy (until 1938), and Molotovsk (until 1957). History Pre-20th century Vikings explored the territories around the North Dvina River - part of Bjarmaland - at the start of the second millennium. British and NormanSeverodvinsk—test of strength (Russian), "Pravda Severa" publishing house, 1998 ships came to these places for mining, fur and fishing before the 13th century, but later the climate became colder and access to the northern seas became closed.

Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

RK-55
The Novator RK-55 ''Relief'' (russian: РК-55 Рельеф 'Relief'; NATO: SSC-X-4 'Slingshot'; GRAU: 3K12) is a Russian land-based and submarine-launched cruise missile with a nuclear warhead developed in the Soviet Union. It was about to enter service in 1987, when such weapons were banned under the Intermediate-Range Nuclear Forces Treaty. A version launched from submarine torpedo tubes, the S-10 ''Granat'' (SS-N-21 'Sampson'; GRAU: 3K10), has apparently been converted to carry conventional warheads and continues in service to this day. The Russian Federation was reported to have deployed the derivative SS-CX-7/SS-CX-8 systems on February 14, 2017. The RK-55 is very similar to the air-launched Kh-55 (AS-15 'Kent') but the Kh-55 has a drop-down turbofan engine and was designed by MKB Raduga. Both have formed the basis of post-Cold-War missiles, in particular the 3M-54 Kalibr which has a supersonic approach phase. Development In the late 1960s, the "Ekho" study conducted by ...

RPK-2 Viyuga
The RPK-2 Vyuga (, ''blizzard''; NATO reporting name: SS-N-15 Starfish), also designated as 81R, is a Soviet submarine-launched, nuclear-armed anti-submarine missile system, launched exclusively through torpedo tubes. The system was designed in Sverdlovsk, Russian SFSR in the 1960s. Analogous to the SUBROC missile previously used by the US Navy, it is designed to be fired from a 533 mm torpedo tube. It is boosted by a choice of mechanisms depending on model before clearing the water, firing a solid fuel rocket and delivering its payload up to away. The payload ranges from a simple depth charge to a 200 kt thermonuclear warhead. Design The RPK-2 uses a 82R torpedo or 90R nuclear depth charge in the 533 mm version, and a 83R torpedo carrying or 86R nuclear depth charge in 650 mm version. Both submarine- and surface-launched versions exist. The surface-launched versions are used by the , , and classes. The submarine-launched versions are used by the , , , , , an ...

SS-N-16
RPK-6 ''Vodopad'' (, "waterfall") is a Soviet 533 mm anti-submarine missile deployed operationally since 1981. RPK-7 ''Veter'' (, "wind") is a 650 mm version, deployed operationally since 1984. Both missiles are given the same United States Navy designation SS-N-16 and NATO designation ''Stallion''. Both missiles are torpedo-tube launched, with a solid-fuel rocket engine to power them above the surface. Both missiles are dual-role; they can be armed with either a 400 mm anti-submarine torpedo or a nuclear depth charge. The Veter's increased range of approximately 100 kilometers was an impressive boost over its predecessor the SS-N-15 Starfish, which could only reach half the distance. Specifications (RPK-7 Veter) Performance: * Range: 100 km (55 nmi) Payload: * Nuclear depth charge or 400 mm torpedo Guidance: *inertial guidance An inertial navigation system (INS) is a navigation device that uses motion sensors (accelerometers), rotation sensors ( gyroscopes) ...

Submarine Incident Off Kildin Island
The submarine incident off Kildin Island was a collision between the US Navy nuclear submarine and the Russian Navy nuclear submarine B-276 ''Kostroma'' near the Russian naval base of Severomorsk on 11 February 1992. The incident occurred while the US unit was engaged in a covert mission, apparently aimed at intercepting Russian military communications. Although a majority of sources claim that the American submarine was trailing her Russian counterpart, some authors believe that neither ''Kostroma'' nor ''Baton Rouge'' had been able to locate each other before the collision. Background Following the fall of the Soviet Union in 1991, uncertainty prevailed among the US intelligence community about the attitude of the former Soviet forces, especially the strategic assets that remained under Russian control. The US government tasked the Navy to continue keeping a close watch on the main bases of Russian nuclear submarines to monitor developments. During the cold war, this typ ...
