The very low acoustic signature has been achieved by incremental design improvements to minimise noise generation and transmission – for example, the installation of active noise cancellation techniques. In Occidente sono conosciuti con … This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. [35] The U.S. Northern Command confirmed that this 2009 Akula-class submarine deployment did occur. The submarine is also able to use its torpedo tubes to deploy mines. Projekti 971 "Štšuka-B"-luokan sukellusveneet (ven. The name Akula is the NATO reporting name for what is called the Project 971 Shchuka-B submarine in Russia. Apalkov, Sankt Peterburg, 2003, ISBN 5-8172-0072-4. All submarines before K-391 Bratsk have reactor coolant scoops that are similar to the ones of the Typhoon class SSBNs, long and tubular. A number of Russian Akula class submarines are deployed in the Pacific region. It is longer and has a larger displacement compared to the Akula II. The propulsion system drives a seven-bladed fixed-pitch propeller. This is a replica of the Russian attack submarine K-157 “Vepr”. ", "The Akula Class submarines carry up to 12 Granit submarine-launched cruise missiles.". [11] All were retrofitted with the SOCKS hydrodynamic sensors except Volk. [36], In August 2012, the news media reported that another Akula-class submarine operated in the Gulf of Mexico purportedly undetected for over a month, sparking controversy within U.S. military and political circles, with U.S. Construction halted at 60% completion. Sappiamo che gli Akula Progetto 971U K-337 Kuguare e K-333 Rys ed il Progetto 971 K-480 Ak Bars sono stati trasformati in Borei. Three additional boats the Belgograd and Kuguar launched in the late 1990s as Akula II class boats. Nerpa and Iribis (not completed) have a different rescue chamber in the sail. surfaced:8,140 tons Akula I and Akula I Improved8,450–8,470 tons Akula II and III, 4 × 533mm torpedo tubes (28 torpedoes) and 4 × 650mm torpedo tubes (12 torpedoes) The added space was used for additional quieting measures. Akula is a nuclear-powered attack submarine first deployed by the Soviet navy in 1986. On 27 October 2008, it was reported that K-152 Nerpa of the Russian Pacific Fleet had begun her sea trials in the Sea of Japan before handover under a lease agreement to the Indian Navy. The Akula II is three meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. RBS 15 Gungnir is the next-generation missile in the RBS 15 family of anti-ship missile systems offered by Saab Group.…, The P-3C Orion land-based maritime patrol and anti-submarine warfare aircraft is operational in the airforces of ten countries. U.S Navy officials and Congressmen announced that this technology enabled the Soviet submarine builders to produce more accurate and quieter propellers.[15]. (K-152 Nerpa has 8 × 533mm torpedo tubes) 40 torpedoes total, Project 971 Щука-Б (Shchuka-B, 'Shchuka' meaning pike, NATO reporting name "Akula"), is a nuclear-powered attack submarine (SSN) first deployed by the Soviet Navy in 1986. These torpedo tubes are arranged in two rows of four tubes each. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarines (SSN). Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. The Akula Class carry up to 12 Granit submarine-launched cruise missiles. These boats are equipped with MGK-500 Skat sonar system (with NATO reporting name Shark Gill). NATO designated the Project 971 boats as Akula I, and the Project 971U as "Improved Akula I" while Project 971A was designated Akula II. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. Senator John Cornyn of the Senate Armed Services Committee demanding details of this deployment from Admiral Jonathan W. Greenert, the Chief of Naval Operations. Smaller, harder to detect, and more mobile, the last Akula II, the Open Aggression remained in operation until 3083, when it was finally sunk off the coast of South Africa. Boat Nepra began sea trials in … In Russia Akula means Shark. K-335 Gepard is the only completed Akula III (see table for others)[citation needed](There is no AKULA III NATO classification). These submarines are much quieter than early Akula class submarines and all have the SOCKS hydrodynamic sensors except Leopard. 21 Jun, 2011, 10.06 PM IST This design requires more power than single-hull submarines[citation needed] because of the greater wetted surface area, which increases drag. [14] Two of these submarines were used to build the Borei class SSBNs. The Akula II submarines are 110m long and displace up to 12,770t. [26] INS Chakra was officially inducted into the Indian Navy on April 4, 2012.[27][28]. The submarine is fitted with the MGK 540 sonar system which provides automatic target detection in broad and narrow-band modes by active sonar. Project 971 Shuka-B Bars-class Akula class Attack Submarine (Nuclear Powered) The Project 971, using a steel hull, was initiated in 1976 when it became evident that existing industrial infrastructure was inadequate to mass produce the expensive titanium hulls of the Project 945 Sierra class. The name Akula was used as the NATO designation of the Projekt 971 because the first of the class was the K-284 christened Akula. The four known variants within the Akula class. The distinctive "bulb" or "can" seen on top of the Akula's rudder houses its towed sonar array, when retracted. snow leopard). 2:16. hauki, Nato-raportointinimi Akula) ovat Venäjän laivaston ydinkäyttöisiä hyökkäyssukellusveneitä..

La Classe Akula, nome in codice NATO della classe di sottomarini nucleari sovietici Progetto 971 Ščuka-B, è entrata in servizio a partire dagli anni ottanta. The Virginia-class submarines can, however, go one further. Improved Akulas, Akula IIs have an additional six 533 mm torpedo tubes mounted externally, capable of launching possibly up to 6 decoys each[citation needed]. The Vepr was built to further improved Project 971M (or Akula II class). The added space was used for additional quieting measures. The sonar signal processor can detect and automatically classify targets as well as reject spurious acoustic noise sources and compensate for variable acoustic conditions. [8][9] The lead boat of the class, K-284 'Akula' was decommissioned in 2001, apparently to help save money in the cash-strapped Russian Navy. The Akula II is approximately 230 tons larger in displacement and 2.5m greater in LOA compared to that of the Akula I's. The 650 mm tubes can be fitted with liners to use the 533 mm weaponry. The torpedo tubes can be used to launch mines instead of torpedoes. Bratsk and subsequent submarines have reactor coolant scoops similar to the ones on the Oscar IIs, short and (the Typhoon, Akula and Oscar classes use the similar OK-650 reactor). The submarine’s anti-ship missiles are the Novator SS-N-15 Starfish and the Novator SS-N-16 Stallion. They are located on the leading edge of the sail, on the outer hull casing in front of the sail and on the bottom of the hull forward of the sail. The tail setup is very similar to that of the FH-1 Hunter, being a fenestron, but the rearranged fins makes it similar to that of the Airbus Helicopters H145M, but with a wider and lower tail structure similar to a Kawasa… The submarine has eight torpedo launch tubes, four 650mm and four 533mm tubes. The CEP (the circle of equal probability) is 150m. [citation needed] The Russians call all of the submarines Schuka-B, regardless of modifications.[7]. While the “Vepr” is an Akula-II class vessel (project 971U), the other four ships belong to the slightly older class Akula-1 (project 971). The land attack Granit missile uses inertial and terrain following guidance. The surface search radar antennae are installed on the same mast as the Rim Hat radar intercept receiver.

Apalkov, Sankt Peterburg, 2003, ISBN 5-8172-0070-8, Adm. Boorda, statement at a meeting of the Naval & Maritime Correspondents Circle, Washington, D.C. 27 Feb 1995, "Quieter Soviet subs cost U.S. at least $30 billion", Navy News & Undersea Technology (14 March 1988), Korabli VMF SSSR, Vol. The retractable masts viewed from bow to stern are the periscopes, radar antennae, radio and satellite communications and navigation masts. The very low acoustic signature has been achieved by incremental design improvements to minimise noise generation and transmission – for example, the installation of active noise cancellation techniques. In Occidente sono conosciuti con … This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. [35] The U.S. Northern Command confirmed that this 2009 Akula-class submarine deployment did occur. The submarine is also able to use its torpedo tubes to deploy mines. Projekti 971 "Štšuka-B"-luokan sukellusveneet (ven. The name Akula is the NATO reporting name for what is called the Project 971 Shchuka-B submarine in Russia. Apalkov, Sankt Peterburg, 2003, ISBN 5-8172-0072-4. All submarines before K-391 Bratsk have reactor coolant scoops that are similar to the ones of the Typhoon class SSBNs, long and tubular. A number of Russian Akula class submarines are deployed in the Pacific region. It is longer and has a larger displacement compared to the Akula II. The propulsion system drives a seven-bladed fixed-pitch propeller. This is a replica of the Russian attack submarine K-157 “Vepr”. ", "The Akula Class submarines carry up to 12 Granit submarine-launched cruise missiles.". [11] All were retrofitted with the SOCKS hydrodynamic sensors except Volk. [36], In August 2012, the news media reported that another Akula-class submarine operated in the Gulf of Mexico purportedly undetected for over a month, sparking controversy within U.S. military and political circles, with U.S. Construction halted at 60% completion. Sappiamo che gli Akula Progetto 971U K-337 Kuguare e K-333 Rys ed il Progetto 971 K-480 Ak Bars sono stati trasformati in Borei. Three additional boats the Belgograd and Kuguar launched in the late 1990s as Akula II class boats. Nerpa and Iribis (not completed) have a different rescue chamber in the sail. surfaced:8,140 tons Akula I and Akula I Improved8,450–8,470 tons Akula II and III, 4 × 533mm torpedo tubes (28 torpedoes) and 4 × 650mm torpedo tubes (12 torpedoes) The added space was used for additional quieting measures. Akula is a nuclear-powered attack submarine first deployed by the Soviet navy in 1986. On 27 October 2008, it was reported that K-152 Nerpa of the Russian Pacific Fleet had begun her sea trials in the Sea of Japan before handover under a lease agreement to the Indian Navy. The Akula II is three meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. RBS 15 Gungnir is the next-generation missile in the RBS 15 family of anti-ship missile systems offered by Saab Group.…, The P-3C Orion land-based maritime patrol and anti-submarine warfare aircraft is operational in the airforces of ten countries. U.S Navy officials and Congressmen announced that this technology enabled the Soviet submarine builders to produce more accurate and quieter propellers.[15]. (K-152 Nerpa has 8 × 533mm torpedo tubes) 40 torpedoes total, Project 971 Щука-Б (Shchuka-B, 'Shchuka' meaning pike, NATO reporting name "Akula"), is a nuclear-powered attack submarine (SSN) first deployed by the Soviet Navy in 1986. These torpedo tubes are arranged in two rows of four tubes each. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarines (SSN). Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. The Akula Class carry up to 12 Granit submarine-launched cruise missiles. These boats are equipped with MGK-500 Skat sonar system (with NATO reporting name Shark Gill). NATO designated the Project 971 boats as Akula I, and the Project 971U as "Improved Akula I" while Project 971A was designated Akula II. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. Senator John Cornyn of the Senate Armed Services Committee demanding details of this deployment from Admiral Jonathan W. Greenert, the Chief of Naval Operations. Smaller, harder to detect, and more mobile, the last Akula II, the Open Aggression remained in operation until 3083, when it was finally sunk off the coast of South Africa. Boat Nepra began sea trials in … In Russia Akula means Shark. K-335 Gepard is the only completed Akula III (see table for others)[citation needed](There is no AKULA III NATO classification). These submarines are much quieter than early Akula class submarines and all have the SOCKS hydrodynamic sensors except Leopard. 21 Jun, 2011, 10.06 PM IST This design requires more power than single-hull submarines[citation needed] because of the greater wetted surface area, which increases drag. [14] Two of these submarines were used to build the Borei class SSBNs. The Akula II submarines are 110m long and displace up to 12,770t. [26] INS Chakra was officially inducted into the Indian Navy on April 4, 2012.[27][28]. The submarine is fitted with the MGK 540 sonar system which provides automatic target detection in broad and narrow-band modes by active sonar. Project 971 Shuka-B Bars-class Akula class Attack Submarine (Nuclear Powered) The Project 971, using a steel hull, was initiated in 1976 when it became evident that existing industrial infrastructure was inadequate to mass produce the expensive titanium hulls of the Project 945 Sierra class. The name Akula was used as the NATO designation of the Projekt 971 because the first of the class was the K-284 christened Akula. The four known variants within the Akula class. The distinctive "bulb" or "can" seen on top of the Akula's rudder houses its towed sonar array, when retracted. snow leopard). 2:16. hauki, Nato-raportointinimi Akula) ovat Venäjän laivaston ydinkäyttöisiä hyökkäyssukellusveneitä.. Projekti 971-luokan aluksia on Venäjän laivastolla 14. La Classe Akula, nome in codice NATO della classe di sottomarini nucleari sovietici Progetto 971 Ščuka-B, è entrata in servizio a partire dagli anni ottanta. The Virginia-class submarines can, however, go one further. Improved Akulas, Akula IIs have an additional six 533 mm torpedo tubes mounted externally, capable of launching possibly up to 6 decoys each[citation needed]. The Vepr was built to further improved Project 971M (or Akula II class). The added space was used for additional quieting measures. The sonar signal processor can detect and automatically classify targets as well as reject spurious acoustic noise sources and compensate for variable acoustic conditions. [8][9] The lead boat of the class, K-284 'Akula' was decommissioned in 2001, apparently to help save money in the cash-strapped Russian Navy. The Akula II is approximately 230 tons larger in displacement and 2.5m greater in LOA compared to that of the Akula I's. The 650 mm tubes can be fitted with liners to use the 533 mm weaponry. The torpedo tubes can be used to launch mines instead of torpedoes. Bratsk and subsequent submarines have reactor coolant scoops similar to the ones on the Oscar IIs, short and (the Typhoon, Akula and Oscar classes use the similar OK-650 reactor). The submarine’s anti-ship missiles are the Novator SS-N-15 Starfish and the Novator SS-N-16 Stallion. They are located on the leading edge of the sail, on the outer hull casing in front of the sail and on the bottom of the hull forward of the sail. The tail setup is very similar to that of the FH-1 Hunter, being a fenestron, but the rearranged fins makes it similar to that of the Airbus Helicopters H145M, but with a wider and lower tail structure similar to a Kawasa… The submarine has eight torpedo launch tubes, four 650mm and four 533mm tubes. The CEP (the circle of equal probability) is 150m. [citation needed] The Russians call all of the submarines Schuka-B, regardless of modifications.[7]. While the “Vepr” is an Akula-II class vessel (project 971U), the other four ships belong to the slightly older class Akula-1 (project 971). The land attack Granit missile uses inertial and terrain following guidance. The surface search radar antennae are installed on the same mast as the Rim Hat radar intercept receiver.

A reserve propeller system, powered by two motors rated at 370kW, provides a speed of 3kt to 4kt. This probably includes the use of rafting for the machinery, as well as "air pillows" to cushion certain pieces of equipment. Whereas the Russian Navy's Akula-II could be equipped with 28 nuclear-capable cruise missiles with a striking range of 3,000 km (1,620 nmi; 1,864 mi), the Indian version was reportedly expected to be armed with the 300 km (162 nmi; 186 mi)-range 3M-54 Klub nuclear-capable missiles. The submarine will be named INS Chakra as was the previous India-leased Soviet Charlie-I SSGN. pike ', NATO reporting name Akula) are a series of nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. The six Akulas of this class are all thought to be in service. The Stallion, fired from the 650mm tubes, has a longer range of up to 100km. The vessel was completed at the Komsomolsk-on-Amur shipyard and commissioned to the Russian Navy in December 2009. One of this class was used to complete the Borei SSBNs. [13] K-157 Vepr became the first Soviet submarine that was quieter than the latest U.S. attack submarines of that time, which was the Improved Los Angeles class (SSN 751 and later). Lo sviluppo del Progetto 971 iniziò nel 1976, quando i responsabili della pianificazione militare sovietica si resero conto che le infrastrutture industriali esistenti erano inadeguate a produrre (a costi ragionevoli) le enormi quantità di titanio necessarie per la costruzione dei sommergibili classe Sierra (Progetto 945) . Two auxiliary diesels rated at 750hp provide emergency power. The Akula II is some meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. At least two more were projected but were not built. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarine, Amur Shipbuilding Plant, Komsomolsk and Sevmash, Severodvinsk, 28 Stallion and Starfish missiles, mk40 torpedoes, anti-submarine missiles and torpedoes in a range of variants, Strela portable missile – 18 missiles, Automated radio communication system

The hull has seven compartments and the stand-off distance between the outer and inner hulls is considerable, reducing the possible inner hull damage. 1, Part 2, Yu. Dozens of others suffered freon-related injuries and were evacuated to an unknown port in Primorsky Krai. Technical Specifications, Revision 01 Starfleet Corps of Engineering Originally built in the early to mid 23rd century, Akula class followed alot of the same design and equipment advances as both the Constitution Class and the Miranda class. Projekt 971 Щука-Б suom. The name Akula (Акула meaning "shark" in Russian) is the Soviet designation of the ballistic missile submarine class designated by NATO as the Typhoon class submarine. Compared to the SIERRA-I, the -II model featured an enlarged sail with two rather than one escape pods in it. La classe Borei I/II sfrutta le sezioni frontali degli Akula incompleti: la larghezza dello scafo coincide esattamente. Martin Searle 546 views. K-157 Vepr is the only completed Akula II[citation needed]. The Russian “Akula” type II nuclear attack submarine is an improved version of the “Akula” type I. E’ certamente una dotazione insolita per un boomer, ma è la medesima degli Akula. The submarine, renamed INS Chakra, was recommissioned by the Indian Navy in April 2012. Again, more noise reduction methods were employed. Elsie Raven 647,259 views. The Starfish, fired from the 533mm tubes, has a target range of 45km. India has finalized a deal with Russia, in which at the end of the lease of these submarines, it has an option to buy them. This design requires more power than single-hull submarines[citation needed]because of the greater wetted surface area, which increases drag. As with many Soviet/Russian craft, information on the status of the Akula Class submarines is sparse, at best. These are where the OK-300 auxiliary propulsion devices are located, which can propel the submarine at up to 5 knots (9.3 km/h). The submarines were built by the Amur Shipbuilding Plant Joint Stock Company at Komsomolsk-on-Amur and by Sevmash at the Severodvinsk shipbuilding yard. These include Akula I, improved Akula, and Akula II variants of the class. Three Akula II submarines, with hull length extended by 4m and advanced machinery-quietening technology, have been built. Initially, the Akula II submarine was scheduled to be delivered to India in Augu… The Russian Navy currently operates five Akula-class SSN’s in the Pacific and six in the Northern Fleet. Most Akulas have the SOCKS[citation needed] hydrodynamic sensors, which detect changes in temperature and salinity. The hull of the “Akula” type II is longer than the type I; 2.5 meters and the weight is increased to 230 tons. The 1999–2000 edition of Jane's Fighting Ships incorrectly listed the first Akula-II as Viper (the actual name is "Vepr", "wild boar" in Russian), commissioned November 25, 1995, Gepard (Cheetah), launched 1999 and commissioned December 5, 2001, and Nerpa, laid down in 1993[1] began sea trials in October, 2008 and was commissioned by the Indian Navy as INS Chakra II in April 2012. Mark, Mazzette; Thom Shanker (August 6, 2009). Related: Leak may reveal Russia’s answer to the Virginia class attack submarine. The MGK-501 Skat sonar system on Akula-I is replaced to a new MGK-540 Skat-3 sonar system. [10] 'Pantera' returned to service in January 2008 after a comprehensive overhaul. Initially, the Akula II submarine was scheduled to be delivered to India in August 2007. Line drawing showing the starboard side of the Project 971 (Akula) Soviet submarine.

Boorda, statement at a meeting of the Naval & Maritime Correspondents Circle, Washington, D.C. 27 Feb 1995, "Quieter Soviet subs cost U.S. at least $30 billion", Navy News & Undersea Technology (14 March 1988), Korabli VMF SSSR, Vol. The retractable masts viewed from bow to stern are the periscopes, radar antennae, radio and satellite communications and navigation masts. The very low acoustic signature has been achieved by incremental design improvements to minimise noise generation and transmission – for example, the installation of active noise cancellation techniques. In Occidente sono conosciuti con … This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. [35] The U.S. Northern Command confirmed that this 2009 Akula-class submarine deployment did occur. The submarine is also able to use its torpedo tubes to deploy mines. Projekti 971 "Štšuka-B"-luokan sukellusveneet (ven. The name Akula is the NATO reporting name for what is called the Project 971 Shchuka-B submarine in Russia. Apalkov, Sankt Peterburg, 2003, ISBN 5-8172-0072-4. All submarines before K-391 Bratsk have reactor coolant scoops that are similar to the ones of the Typhoon class SSBNs, long and tubular. A number of Russian Akula class submarines are deployed in the Pacific region. It is longer and has a larger displacement compared to the Akula II. The propulsion system drives a seven-bladed fixed-pitch propeller. This is a replica of the Russian attack submarine K-157 “Vepr”. ", "The Akula Class submarines carry up to 12 Granit submarine-launched cruise missiles.". [11] All were retrofitted with the SOCKS hydrodynamic sensors except Volk. [36], In August 2012, the news media reported that another Akula-class submarine operated in the Gulf of Mexico purportedly undetected for over a month, sparking controversy within U.S. military and political circles, with U.S. Construction halted at 60% completion. Sappiamo che gli Akula Progetto 971U K-337 Kuguare e K-333 Rys ed il Progetto 971 K-480 Ak Bars sono stati trasformati in Borei. Three additional boats the Belgograd and Kuguar launched in the late 1990s as Akula II class boats. Nerpa and Iribis (not completed) have a different rescue chamber in the sail. surfaced:8,140 tons Akula I and Akula I Improved8,450–8,470 tons Akula II and III, 4 × 533mm torpedo tubes (28 torpedoes) and 4 × 650mm torpedo tubes (12 torpedoes) The added space was used for additional quieting measures. Akula is a nuclear-powered attack submarine first deployed by the Soviet navy in 1986. On 27 October 2008, it was reported that K-152 Nerpa of the Russian Pacific Fleet had begun her sea trials in the Sea of Japan before handover under a lease agreement to the Indian Navy. The Akula II is three meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. RBS 15 Gungnir is the next-generation missile in the RBS 15 family of anti-ship missile systems offered by Saab Group.…, The P-3C Orion land-based maritime patrol and anti-submarine warfare aircraft is operational in the airforces of ten countries. U.S Navy officials and Congressmen announced that this technology enabled the Soviet submarine builders to produce more accurate and quieter propellers.[15]. (K-152 Nerpa has 8 × 533mm torpedo tubes) 40 torpedoes total, Project 971 Щука-Б (Shchuka-B, 'Shchuka' meaning pike, NATO reporting name "Akula"), is a nuclear-powered attack submarine (SSN) first deployed by the Soviet Navy in 1986. These torpedo tubes are arranged in two rows of four tubes each. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarines (SSN). Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. The Akula Class carry up to 12 Granit submarine-launched cruise missiles. These boats are equipped with MGK-500 Skat sonar system (with NATO reporting name Shark Gill). NATO designated the Project 971 boats as Akula I, and the Project 971U as "Improved Akula I" while Project 971A was designated Akula II. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. Senator John Cornyn of the Senate Armed Services Committee demanding details of this deployment from Admiral Jonathan W. Greenert, the Chief of Naval Operations. Smaller, harder to detect, and more mobile, the last Akula II, the Open Aggression remained in operation until 3083, when it was finally sunk off the coast of South Africa. Boat Nepra began sea trials in … In Russia Akula means Shark. K-335 Gepard is the only completed Akula III (see table for others)[citation needed](There is no AKULA III NATO classification). These submarines are much quieter than early Akula class submarines and all have the SOCKS hydrodynamic sensors except Leopard. 21 Jun, 2011, 10.06 PM IST This design requires more power than single-hull submarines[citation needed] because of the greater wetted surface area, which increases drag. [14] Two of these submarines were used to build the Borei class SSBNs. The Akula II submarines are 110m long and displace up to 12,770t. [26] INS Chakra was officially inducted into the Indian Navy on April 4, 2012.[27][28]. The submarine is fitted with the MGK 540 sonar system which provides automatic target detection in broad and narrow-band modes by active sonar. Project 971 Shuka-B Bars-class Akula class Attack Submarine (Nuclear Powered) The Project 971, using a steel hull, was initiated in 1976 when it became evident that existing industrial infrastructure was inadequate to mass produce the expensive titanium hulls of the Project 945 Sierra class. The name Akula was used as the NATO designation of the Projekt 971 because the first of the class was the K-284 christened Akula. The four known variants within the Akula class. The distinctive "bulb" or "can" seen on top of the Akula's rudder houses its towed sonar array, when retracted. snow leopard). 2:16. hauki, Nato-raportointinimi Akula) ovat Venäjän laivaston ydinkäyttöisiä hyökkäyssukellusveneitä.. Projekti 971-luokan aluksia on Venäjän laivastolla 14. La Classe Akula, nome in codice NATO della classe di sottomarini nucleari sovietici Progetto 971 Ščuka-B, è entrata in servizio a partire dagli anni ottanta. The Virginia-class submarines can, however, go one further. Improved Akulas, Akula IIs have an additional six 533 mm torpedo tubes mounted externally, capable of launching possibly up to 6 decoys each[citation needed]. The Vepr was built to further improved Project 971M (or Akula II class). The added space was used for additional quieting measures. The sonar signal processor can detect and automatically classify targets as well as reject spurious acoustic noise sources and compensate for variable acoustic conditions. [8][9] The lead boat of the class, K-284 'Akula' was decommissioned in 2001, apparently to help save money in the cash-strapped Russian Navy. The Akula II is approximately 230 tons larger in displacement and 2.5m greater in LOA compared to that of the Akula I's. The 650 mm tubes can be fitted with liners to use the 533 mm weaponry. The torpedo tubes can be used to launch mines instead of torpedoes. Bratsk and subsequent submarines have reactor coolant scoops similar to the ones on the Oscar IIs, short and (the Typhoon, Akula and Oscar classes use the similar OK-650 reactor). The submarine’s anti-ship missiles are the Novator SS-N-15 Starfish and the Novator SS-N-16 Stallion. They are located on the leading edge of the sail, on the outer hull casing in front of the sail and on the bottom of the hull forward of the sail. The tail setup is very similar to that of the FH-1 Hunter, being a fenestron, but the rearranged fins makes it similar to that of the Airbus Helicopters H145M, but with a wider and lower tail structure similar to a Kawasa… The submarine has eight torpedo launch tubes, four 650mm and four 533mm tubes. The CEP (the circle of equal probability) is 150m. [citation needed] The Russians call all of the submarines Schuka-B, regardless of modifications.[7]. While the “Vepr” is an Akula-II class vessel (project 971U), the other four ships belong to the slightly older class Akula-1 (project 971). The land attack Granit missile uses inertial and terrain following guidance. The surface search radar antennae are installed on the same mast as the Rim Hat radar intercept receiver.
