Elsie Raven 647,259 views. 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. The Akula is an attack helicopter based on the Boeing–Sikorsky RAH-66 Comanche, with a canopy that combines the aspects of the Kamov Ka-52 \"Alligator\" (front windows) and the Kamov Ka-50 “Black Shark” (side windows). 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. Improved Akula-I Hulls: K-328 Leopard, K-461 Volk, K-154 Tigr, K-419 Kuzbass, K-295 Samara and K-152 Nerpa. Compared to the SIERRA-I, the -II model featured an enlarged sail with two rather than one escape pods in it. 'pike', NATO reporting name Akula) are a series of nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. Line drawing showing the starboard side of the Project 971 (Akula) Soviet submarine. One of this class was used to complete the Borei SSBNs. 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. The class is also known under the name Bars (eng. These boats are equipped with MGK-500 Skat sonar system (with NATO reporting name Shark Gill). The torpedo tubes can be used to launch mines instead of torpedoes. These include Akula I, improved Akula, and Akula II variants of the class. [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. These submarines are much quieter than early Akula class submarines and all have the SOCKS hydrodynamic sensors except Leopard. The Stallion and the Starfish can be armed with a 200kt warhead or a type 40 torpedo. The four 650mm tubes can be fitted with liners to provide additional 533mm weapon launch capacity. The submarine, renamed INS Chakra, was recommissioned by the Indian Navy in April 2012. 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. Utilising newly-designed anechoic coatings, isolated structures and a new propulsor design, the Virginia-class submarines boast an acoustic signature lower than the Russian Akula-II class submarines, equivalent to that of the Seawolf-class submarines that they were designed to replace. A reserve propeller system, powered by two motors rated at 370kW, provides a speed of 3kt to 4kt. Si tratta di battelli molto temibili, probabilmente i più moderni sommergibili nucleari d'attacco oggi in circolazione (insieme agli americani Seawolf). Again, more noise reduction methods were employed. 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. We use cookies to ensure that we give you the best experience on our website. Akula-II (project 971U) K-157 Vepr is the only completed Akula II [citation needed]. The Akula II submarines are 110m long and displace up to 12,770t. 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. [14] Two of these submarines were used to build the Borei class SSBNs. La classe Borei I/II sfrutta le sezioni frontali degli Akula incompleti: la larghezza dello scafo coincide esattamente. Projekti 971 "Štšuka-B"-luokan sukellusveneet (ven. 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 distinctive "bulb" or "can" seen o… ... Typhoon and Alpha Class RC Subs - Duration: 2:16. Nerpa and Iribis (not completed) have a different rescue chamber in the sail. The Akula Mark-II submarine was a heavily-modified Akula-class attack submarine that was armed with a wide array of torpedoes, a stealth drive, and instead of nuclear warheads, its main armament was a massive Gungnir railgun cannon that fired high-explosive conventional warheads, with a blast radius of . The added space was used for additional quieting measures. [12] The Akula-I Improved submarines have 6 533 mm decoy launching tubes, as do subsequent submarines. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. The Gepard, K-335, is the only Akula III class submarine in service. 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. pike ', NATO reporting name Akula) are a series of nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. 2:16. K-157 Vepr is the only completed Akula II[citation needed]. Projekt 971 Щука-Б suom. This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. The propulsion system provides a maximum submerged speed of 33kt and a surface speed of 10kt. The improved Akula I and Akula II are also designated as Project 971U and Project 971A respectively. [16], Three hundred Indian Navy personnel are being trained in Russia for the operation of the Akula II submarine Nerpa. 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 Stallion, fired from the 650mm tubes, has a longer range of up to 100km. The submarine’s anti-ship missiles are the Novator SS-N-15 Starfish and the Novator SS-N-16 Stallion. One Akula III was built and put in service by the Russian Navy. 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. [citation needed] I can be distinguished by the large dome on the top surface. The submarine is rated for a diving depth to 600m. 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). [10] 'Pantera' returned to service in January 2008 after a comprehensive overhaul. India would receive its first new generation Nerpa Akula-II class nuclear attack submarine, which is undergoing sea trials in Russia. Il risultato di questo sviluppo fu un sottomarino con lo scafo in acciaio, di prestazioni paragonabili ai classe Sierra, ma notevolmente più economico da costruire e da mantenere. The Akula class is a nuclear powered attack submarine of Soviet origin. It gives the range, relative bearing and range rate. The Akula Class submarine was deployed for the first time in 1986 by the Soviet Navy. 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. 1:39. The vessel was completed at the Komsomolsk-on-Amur shipyard and commissioned to the Russian Navy in December 2009. The main machinery consists of a VM-5 pressure water reactor rated at 190MW with a GT3A turbine developing 35MW. All Akulas are armed with four 533 mm torpedo tubes which can use Type 53 torpedoes or the SS-N-15 Starfish missile, and four 650 mm torpedo tubes which can use Type 65 torpedoes or the SS-N-16 Stallion missile. 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… [30] On 8 November 2008, while conducting one of these trials, an accidental activation of the halon-based fire-extinguishing system took place in the fore section of the vessel. The first, Viper, was commissioned in 1995, the second, Nerpa, in December 2000 and the third, Gepard, in August 2001. The Akula incorporates a double hull system composed of an inner pressure hull and an outer "light" hull. All submarines before K-391 Bratsk have reactor coolant scoops that are similar to the ones of the Typhoon class SSBNs, long and tubular. forces, the Akula II prototypes were less threatening, but also harder to combat. The Akula II is some meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. The vessels could now ultmately sail for the Northern Fleet for another 25-30 years. In 1983–1984 the Japanese firm Toshiba sold sophisticated, nine axis milling equipment to the Soviets along with the computer control systems, which were developed by Norwegian firm Kongsberg Vaapenfabrik. The oldest submarine, Akula I, is likely to be removed from service by 2015, while the Gepard Akula II is expected be withdrawn from service by 2025. [34], In August 2009, the news media reported that two Akula-class submarines operated off the East Coast of the United States, with one of the submarines being identified as a Project 971 Shchuka-B type. U.S. military sources noted that this was the first known Russian submarine deployment to the western Atlantic since the end of the Cold War, raising concerns within U.S. military and intelligence communities. The Vepr was built to further improved Project 971M (or Akula II class). The hull has seven compartments and the stand-off distance between the outer and inner hulls is considerable, reducing the possible inner hull damage. The submarine kit “AKULA-II“, 1/96 scale . The Akula class, Soviet designation Project 971 Shchuka-B (Russian: Щука-Б, lit. The MGK-501 Skat sonar system on Akula-I is replaced to a new MGK-540 Skat-3 sonar system. The submarines were built by the Amur Shipbuilding Plant Joint Stock Company at Komsomolsk-on-Amur and by Sevmash at the Severodvinsk shipbuilding yard. Capabilities: The armament of the Akula II is identical to the original Akula class subs. Of the seven original Akula-I submarines, only three are known to still be in service. At least two more were projected but were not built. The missiles are fired from the 533mm torpedo launch tubes. The distinctive "bulb" or "can" seen on top of the Akula's rudder houses its towed sonar array, when retracted. The Russian Navy currently operates five Akula-class SSN’s in the Pacific and six in the Northern Fleet. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarines (SSN). The Akula’s surface search radar is the Snoop Pair or the Snoop Half. Within seconds the halon gas had displaced all breathable air from the compartment. Initially, the Akula II submarine was scheduled to be delivered to India in Augu… [citation needed] The Russians call all of the submarines Schuka-B, regardless of modifications.[7]. May be completed and leased to India. This design requires more power than single-hull submarines[citation needed] because of the greater wetted surface area, which increases drag. Construction halted at 60% completion. The ship utelized similar layouts as both classes, but in a smaller more compact scale. This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. The hull of the “Akula” type II is longer than the type I; 2.5 meters and the weight is increased to 230 tons. E’ certamente una dotazione insolita per un boomer, ma è la medesima degli Akula. [6] There are four sub-classes or flights of Shchuka, consisting of the original seven "Akula I" submarines which were commissioned between 1984 and 1990, six "Improved Akula" submarines commissioned between 1991 and 2009, one "Akula II" submarine commissioned in 1995 and one Akula III commissioned in 2001. Three Akula II submarines, with hull length extended by 4m and advanced machinery-quietening technology, have been built. 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. Delivery was further delayed due to a fatal gas leak causing the deaths of 20 crew members during sea trials in November 2008. The added space was used for an active noise reduction system. In fact, the Akula is credited with being quieter in a number of areas than even the 688i-series Los Angeles-class boats. [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. Seven Akula IIs were built and put in service by the Soviets and then the Russians. The propulsion system drives a seven-bladed fixed-pitch propeller. ", "The Akula Class submarines carry up to 12 Granit submarine-launched cruise missiles.". K-322 'Kashalot' and K-480 'Bars' [Currently Ak Bars] are in reserve. 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). Granit (Nato designation: SS-N-21 Sampson) has a range of about 3,000km and delivers a 200kt warhead. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. This probably includes the use of rafting for the machinery, as well as "air pillows" to cushion certain pieces of equipment. A number of Russian Akula class submarines are deployed in the Pacific region. The land attack Granit missile uses inertial and terrain following guidance. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. 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. Initially, the Akula II submarine was scheduled to be delivered to India in August 2007. Related: Leak may reveal Russia’s answer to the Virginia class attack submarine. Boat Nepra began sea trials in … The submarine will be named INS Chakra as was the previous India-leased Soviet Charlie-I SSGN. Has been leased out to India from the end 2011 to 2020.

The Soviet advances in sound quieting were of considerable concern to the West, for acoustics was long considered the most significant advantage in U.S. submarine technology compared to the Soviets. The CEP value is a measure of the accuracy of strike on the target and is the radius of the circle within which half the strikes will impact. The submarine is also able to use its torpedo tubes to deploy mines. The external tubes are mounted outside the pressure hull in one row, above the torpedo tubes, and can only be reloaded in port or with the assistance of a submarine tender. Senator John Cornyn of the Senate Armed Services Committee demanding details of this deployment from Admiral Jonathan W. Greenert, the Chief of Naval Operations. In Russia Akula means Shark. An air defence capability is provided by a Strela SA-N-5/8 portable missile launcher with 18 missiles. The submarine has a double-hulled configuration with a distinctive high aft fin. As with many Soviet/Russian craft, information on the status of the Akula Class submarines is sparse, at best. Three additional boats the Belgograd and Kuguar launched in the late 1990s as Akula II class boats. 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 Russian “Akula” type II nuclear attack submarine is an improved version of the “Akula” type I. hauki, Nato-raportointinimi Akula) ovat Venäjän laivaston ydinkäyttöisiä hyökkäyssukellusveneitä..

The Akula class was developed in the early 1980's in response to the US Los Angeles class and is considered a quantum leap forward in Soviet submarine technology. 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. Removed from service 1998. [37], Podvodnye Lodki, Yu.V. Dozens of others suffered freon-related injuries and were evacuated to an unknown port in Primorsky Krai. Pacific Fleet. 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. It is longer and has a larger displacement compared to the Akula II. India to get Nerpa Akula-II N-submarine this year: Russian Official. 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) . for display model or R/C conversion "Scale Model Ship" offers you a submarine kit of the Project 971 “Schuka-B” (SSN “Akula-II” class).
