[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 submarine itself did not sustain any serious damage and there was no release of radiation. Of the seven original Akula-I submarines, only three are known to still be in service. The four known variants within the Akula class. 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). 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. India to get Nerpa Akula-II N-submarine this year: Russian Official 21 Jun, 2011, 10.06 PM IST. Removed from service 1998. An improved version of the earlier Akula I, the -II is notable for its improved quieting. 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. Delivery was further delayed due to a fatal gas leak causing the deaths of 20 crew members during sea trials in November 2008. They have a maximum speed of 35kt submerged and a maximum diving depth of 600m. 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. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. ", "The Akula Class submarines carry up to 12 Granit submarine-launched cruise missiles.". 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). K-322 'Kashalot' and K-480 'Bars' [Currently Ak Bars] are in reserve. Si tratta di battelli molto temibili, probabilmente i più moderni sommergibili nucleari d'attacco oggi in circolazione (insieme agli americani Seawolf). The Stallion and the Starfish can be armed with a 200kt warhead or a type 40 torpedo. Again, more noise reduction methods were employed. The sonar system can also be used in a passive, listening mode for detection of hostile sonars. This design requires more power than single-hull submarines[citation needed] because of the greater wetted surface area, which increases drag. The submarines were built by the Amur Shipbuilding Plant Joint Stock Company at Komsomolsk-on-Amur and by Sevmash at the Severodvinsk shipbuilding yard. Dozens of others suffered freon-related injuries and were evacuated to an unknown port in Primorsky Krai. One of this class was used to complete the Borei SSBNs. The distinctive "bulb" or "can" seen on top of the Akula's rudder houses its towed sonar array, when retracted. 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 Akula incorporates a double hull system composed of an inner pressure hull and an outer "light" hull. Due to the breakup of the Soviet Union in 1991, production of all Akulas slowed. The Starfish, fired from the 533mm tubes, has a target range of 45km. Information provided by sources varies widely. Apalkov, Sankt Peterburg, 2003, ISBN 5-8172-0072-4. The submarine has a double-hulled configuration with a distinctive high aft fin. Mark, Mazzette; Thom Shanker (August 6, 2009). (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. One of the pods is offset to port and the other to starboard. 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. 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) [29] Missiles with ranges greater than 300 km (162 nmi; 186 mi) cannot be exported due to arms control restrictions, since Russia is a signatory to the MTCR treaty. [16], Three hundred Indian Navy personnel are being trained in Russia for the operation of the Akula II submarine Nerpa. They have a different arrangement of limber holes on the outer hull than Akula Is. [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 sonar signal processor can detect and automatically classify targets as well as reject spurious acoustic noise sources and compensate for variable acoustic conditions. [33] This was the worst accident in the Russian navy since the loss of the submarine K-141 Kursk in 2000. Engel Akula II RC Submarine Bath Test - Duration: 1:39. E’ certamente una dotazione insolita per un boomer, ma è la medesima degli Akula. Pacific Fleet. 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. 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. 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. Senator John Cornyn of the Senate Armed Services Committee demanding details of this deployment from Admiral Jonathan W. Greenert, the Chief of Naval Operations. 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. More than…, The Borei Class is a Russian fourth-generation nuclear-powered missile submarine. 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. In Russia Akula means Shark. The vessels could now ultmately sail for the Northern Fleet for another 25-30 years. 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… forces, the Akula II prototypes were less threatening, but also harder to combat. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarines (SSN). RBS 15 Gungnir Next-Generation Anti-Ship Missile System, SSBN Borei Class Nuclear-Powered Submarines, DASA awards £3m funding for Intelligent Ship competition, Royal Navy commissions final Batch 2 River-class OPV HMS Spey, US Navy’s FRCE delivers last presidential helicopter engine, Saab to supply mine neutraliser for Anglo-French MMCM programme, BAE Systems to demonstrate new RFCM system for P-8A Poseidon. The hull of the “Akula” type II is longer than the type I; 2.5 meters and the weight is increased to 230 tons. Three additional boats the Belgograd and Kuguar launched in the late 1990s as Akula II class boats. The Akula can launch a range of anti-submarine and anti-surface vessel torpedoes. The white cheatline marks the boat's waterline. 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. Compared to the SIERRA-I, the -II model featured an enlarged sail with two rather than one escape pods in it. The Akula II is three meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. The four 650mm tubes can be fitted with liners to provide additional 533mm weapon launch capacity. 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 first, Viper, was commissioned in 1995, the second, Nerpa, in December 2000 and the third, Gepard, in August 2001. 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. As a result, 20 people (17 civilians and 3 seamen)[31][32] were killed by asphyxiation. In fact, the Akula is credited with being quieter in a number of areas than even the 688i-series Los Angeles-class boats. [11] All were retrofitted with the SOCKS hydrodynamic sensors except Volk. It is longer and has a larger displacement compared to the Akula II. 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. 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. The Stallion, fired from the 650mm tubes, has a longer range of up to 100km. U.S Navy officials and Congressmen announced that this technology enabled the Soviet submarine builders to produce more accurate and quieter propellers.[15]. [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). The land attack Granit missile uses inertial and terrain following guidance. Within seconds the halon gas had displaced all breathable air from the compartment. Granit (Nato designation: SS-N-21 Sampson) has a range of about 3,000km and delivers a 200kt warhead. 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). [14] Two of these submarines were used to build the Borei class SSBNs. [citation needed] The Russians call all of the submarines Schuka-B, regardless of modifications.[7]. 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. India would receive its first new generation Nerpa Akula-II class nuclear attack submarine, which is undergoing sea trials in Russia. This probably includes the use of rafting for the machinery, as well as "air pillows" to cushion certain pieces of equipment. It gives the range, relative bearing and range rate. The submarine is rated for a diving depth to 600m. This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. 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 Akula Class carry up to 12 Granit submarine-launched cruise missiles. Questi sottomarini sono in grado di attaccare con successo sia gruppi di unità navali ostili (subacquee e di superficie), sia installazioni costiere [3] . If you continue to use this site we will assume that you are happy with it. 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. This allows more freedom in the design of the exterior hull shape, resulting in a submarine with more reserve buoyancy than its western analogs. K-480 'Bars' was put into reserve in 1998,[1] and is being dismantled in February 2010. Related: Leak may reveal Russia’s answer to the Virginia class attack submarine.

Typhoon and Alpha Class RC Subs - Duration: 2:16. Initially, the Akula II submarine was scheduled to be delivered to India in August 2007. The retractable masts viewed from bow to stern are the periscopes, radar antennae, radio and satellite communications and navigation masts. They were called Akula I, II, and II. Also, it has an enlarged sail and a different towed-array dispenser on the vertical fin. Projekt 971 Щука-Б suom. Akula is a nuclear-powered attack submarine first deployed by the Soviet navy in 1986. The Improved Akula and Akula II have ten, with six 533mm tubes. The Russian Navy currently operates five Akula-class SSN’s in the Pacific and six in the Northern Fleet. 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. A more subtle improvement is an enlarged main sonar, the same MGK-501 Skat passive array fitted to the larger AKULA Class. 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. However, the induction was postponed to 2009 due to recurred delays caused by the installation of new systems and technologies on Nepra and due to an attack on the latest series of Schucka-B or Akula-II Class Russian-built submarines. [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. The submarine kit “AKULA-II“, 1/96 scale . As with many Soviet/Russian craft, information on the status of the Akula Class submarines is sparse, at best. We use cookies to ensure that we give you the best experience on our website. [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. Capabilities: The armament of the Akula II is identical to the original Akula class subs. 2:16. The Virginia-class submarines can, however, go one further. The Vepr was built to further improved Project 971M (or Akula II class). In Occidente sono conosciuti con … 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. 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). One Akula III was built and put in service by the Russian Navy. The ship utelized similar layouts as both classes, but in a smaller more compact scale. Martin Searle 546 views. The added space was used for additional quieting measures. Most Akulas have the SOCKS[citation needed] hydrodynamic sensors, which detect changes in temperature and salinity. The Akula’s surface search radar is the Snoop Pair or the Snoop Half. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. The propulsion system drives a seven-bladed fixed-pitch propeller. May be completed and leased to India. The submarine’s anti-ship missiles are the Novator SS-N-15 Starfish and the Novator SS-N-16 Stallion. The Akula class, Soviet designation Project 971 Shchuka-B (Russian: Щука-Б, lit.

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 Akula II is some meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. 21 Jun, 2011, 10.06 PM IST The 650 mm tubes can be fitted with liners to use the 533 mm weaponry. K-157 Vepr is the only completed Akula II[citation needed]. The Akula class is a nuclear powered attack submarine of Soviet origin. Seven Akula IIs were built and put in service by the Soviets and then the Russians. [citation needed] I can be distinguished by the large dome on the top surface. All submarines before K-391 Bratsk have reactor coolant scoops that are similar to the ones of the Typhoon class SSBNs, long and tubular. They are quieter than the original MGK-500 Skat sonar system on Akula-I is upgraded to the MGK-501 Skat-MS. Sources also disagree as to whether construction of this class has been suspended, or if there are a further two units planned. The Russian “Akula” type II nuclear attack submarine is an improved version of the “Akula” type I. This is a replica of the Russian attack submarine K-157 “Vepr”. snow leopard). The added space was used for additional quieting measures. Northern Fleet. These include Akula I, improved Akula, and Akula II variants of the class. These boats are equipped with MGK-500 Skat sonar system (with NATO reporting name Shark Gill). The MGK-501 Skat sonar system on Akula-I is replaced to a new MGK-540 Skat-3 sonar system. The submarine, renamed INS Chakra, was recommissioned by the Indian Navy in April 2012. Improved Akula-I Hulls: K-328 Leopard, K-461 Volk, K-154 Tigr, K-419 Kuzbass, K-295 Samara and K-152 Nerpa. A number of Russian Akula class submarines are deployed in the Pacific region. India to get Nerpa Akula-II N-submarine this year: Russian Official. These submarines are much quieter than early Akula class submarines and all have the SOCKS hydrodynamic sensors except Leopard. [35] The U.S. Northern Command confirmed that this 2009 Akula-class submarine deployment did occur. Construction of Akula II began in 1991, but it was suspended for a period of ten years due to lack of funds. The main machinery consists of a VM-5 pressure water reactor rated at 190MW with a GT3A turbine developing 35MW. A reserve propeller system, powered by two motors rated at 370kW, provides a speed of 3kt to 4kt. La classe Borei I/II sfrutta le sezioni frontali degli Akula incompleti: la larghezza dello scafo coincide esattamente. Initially, the Akula II submarine was scheduled to be delivered to India in Augu… The Gepard, K-335, is the only Akula III class submarine in service. Nerpa and Iribis (not completed) have a different rescue chamber in the sail. The vessel was completed at the Komsomolsk-on-Amur shipyard and commissioned to the Russian Navy in December 2009.
