Boat Nepra began sea trials in … The Akula II is some meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. [33] This was the worst accident in the Russian navy since the loss of the submarine K-141 Kursk in 2000. A number of Russian Akula class submarines are deployed in the Pacific region. 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). [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 submarine is fitted with the MGK 540 sonar system which provides automatic target detection in broad and narrow-band modes by active sonar. Elsie Raven 647,259 views. It is intended to eventually replace the ageing Delta III…, Type 23 Duke class frigates are multi-role warships built by Swan Hunter and BAE Systems for the UK’s Royal Navy.…, Get important industry news and analysis sent to your inbox – sign up to our e-Newsletter here, "Three Akula II submarines, with advanced machinery-quietening technology, have been built. The vessel was completed at the Komsomolsk-on-Amur shipyard and commissioned to the Russian Navy in December 2009. 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. An improved version of the earlier Akula I, the -II is notable for its improved quieting. As a result, 20 people (17 civilians and 3 seamen)[31][32] were killed by asphyxiation. Seven Akula I submarines were commissioned between 1986 and 1992, and three Improved Akula between 1992 and 1995. The oldest submarine, Akula I, is likely to be removed from service by 2015, while the Gepard Akula II is expected be withdrawn from service by 2025. The Gepard is the most advanced Russian submarine before the submarines of the Severodvinsk and Borei classes are commissioned. Due to the breakup of the Soviet Union in 1991, production of all Akulas slowed. This design requires more power than single-hull submarines[citation needed] because of the greater wetted surface area, which increases drag. 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. These boats are equipped with MGK-500 Skat sonar system (with NATO reporting name Shark Gill). [14] Two of these submarines were used to build the Borei class SSBNs. (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. The Russian Navy has 14 Bars Class project 971 submarines known in the West as the Akula Class nuclear-powered submarines (SSN). 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 hull of the “Akula” type II is longer than the type I; 2.5 meters and the weight is increased to 230 tons. [12] The Akula-I Improved submarines have 6 533 mm decoy launching tubes, as do subsequent submarines. Pacific Fleet. 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. [citation needed]. 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. K-157 Vepr is the only completed Akula II[citation needed]. The submarine is also able to use its torpedo tubes to deploy mines. 1:39. Initially, the Akula II submarine was scheduled to be delivered to India in August 2007. All submarines before K-391 Bratsk have reactor coolant scoops that are similar to the ones of the Typhoon class SSBNs, long and tubular. Granit (Nato designation: SS-N-21 Sampson) has a range of about 3,000km and delivers a 200kt warhead. The vessels could now ultmately sail for the Northern Fleet for another 25-30 years. The added space was used for an active noise reduction system. NATO designated the Project 971 boats as Akula I, and the Project 971U as "Improved Akula I" while Project 971A was designated Akula II. 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 Akula can launch a range of anti-submarine and anti-surface vessel torpedoes. The improved Akula I and Akula II are also designated as Project 971U and Project 971A respectively. The Akula Class submarine was deployed for the first time in 1986 by the Soviet Navy. Seven Akula IIs were built and put in service by the Soviets and then the Russians. Has been leased out to India from the end 2011 to 2020. 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. 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). 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. This probably includes the use of rafting for the machinery, as well as "air pillows" to cushion certain pieces of equipment. The surface search radar antennae are installed on the same mast as the Rim Hat radar intercept receiver. Improved Akula-I Hulls: K-328 Leopard, K-461 Volk, K-154 Tigr, K-419 Kuzbass, K-295 Samara and K-152 Nerpa. The land attack Granit missile uses inertial and terrain following guidance. The Virginia-class submarines can, however, go one further. 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 Akula II submarines are 110m long and displace up to 12,770t. The Akula class, Soviet designation Project 971 Shchuka-B (Russian: Щука-Б, lit. They have a maximum speed of 35kt submerged and a maximum diving depth of 600m. The Indian Navy signed an agreement with Russia to lease a new Akula II submarine, the SSN Nerpa, for ten years. Delivery was further delayed due to a fatal gas leak causing the deaths of 20 crew members during sea trials in November 2008. Most Akulas have the SOCKS[citation needed] hydrodynamic sensors, which detect changes in temperature and salinity. 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

Air defence periscope. It is longer and has a larger displacement compared to the Akula II. 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 Russian “Akula” type II nuclear attack submarine is an improved version of the “Akula” type I. [35] The U.S. Northern Command confirmed that this 2009 Akula-class submarine deployment did occur. Capabilities: The armament of the Akula II is identical to the original Akula class subs. The Akula II is three meters longer and displaces about 700 tons (submerged displacement) more than the Akula I. 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. The MGK-501 Skat sonar system on Akula-I is replaced to a new MGK-540 Skat-3 sonar system. Line drawing showing the starboard side of the Project 971 (Akula) Soviet submarine. ... Typhoon and Alpha Class RC Subs - Duration: 2:16. The propulsion system drives a seven-bladed fixed-pitch propeller. Two auxiliary diesels rated at 750hp provide emergency power. 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 added space was used for additional quieting measures. The submarine will be named INS Chakra as was the previous India-leased Soviet Charlie-I SSGN. Removed from service 1998. In Occidente sono conosciuti con … The Stallion and the Starfish can be armed with a 200kt warhead or a type 40 torpedo. The missiles are fired from the 533mm torpedo launch tubes. The submarine, renamed INS Chakra, was recommissioned by the Indian Navy in April 2012. 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. Again, more noise reduction methods were employed. The Akula Class carry up to 12 Granit submarine-launched cruise missiles. 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. Engel Akula II RC Submarine Bath Test - Duration: 1:39. Apalkov, Sankt Peterburg, 2003, ISBN 5-8172-0072-4. The added space was used for additional quieting measures. In fact, the Akula is credited with being quieter in a number of areas than even the 688i-series Los Angeles-class boats. 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 CEP (the circle of equal probability) is 150m. Akula-II (project 971U) K-157 Vepr is the only completed Akula II [citation needed]. The Starfish, fired from the 533mm tubes, has a target range of 45km. In Russia Akula means Shark. [16], Three hundred Indian Navy personnel are being trained in Russia for the operation of the Akula II submarine Nerpa. 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. 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. 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. Also, it has an enlarged sail and a different towed-array dispenser on the vertical fin. 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). The Vepr was built to further improved Project 971M (or Akula II 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. More than…, The Borei Class is a Russian fourth-generation nuclear-powered missile submarine. 1, Part 2, Yu. 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. 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 Akula incorporates a double hull system composed of an inner pressure hull and an outer "light" hull. One of the pods is offset to port and the other to starboard. India would receive its first new generation Nerpa Akula-II class nuclear attack submarine, which is undergoing sea trials in Russia. The Akula class, Soviet designation Project 971 Shchuka-B (Russian: Щука-Б, lit. ' The submarine itself did not sustain any serious damage and there was no release of radiation. Three Akula II submarines, with hull length extended by 4m and advanced machinery-quietening technology, have been built. They were called Akula I, II, and II. Akula is a nuclear-powered attack submarine first deployed by the Soviet navy in 1986. The distinctive "bulb" or "can" seen on top of the Akula's rudder houses its towed sonar array, when retracted. Initially, the Akula II submarine was scheduled to be delivered to India in Augu… The main machinery consists of a VM-5 pressure water reactor rated at 190MW with a GT3A turbine developing 35MW. The sonar signal processor can detect and automatically classify targets as well as reject spurious acoustic noise sources and compensate for variable acoustic conditions. India to get Nerpa Akula-II N-submarine this year: Russian Official. [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. The name Akula is the NATO reporting name for what is called the Project 971 Shchuka-B submarine in Russia. These torpedo tubes are arranged in two rows of four tubes each. If you continue to use this site we will assume that you are happy with it. forces, the Akula II prototypes were less threatening, but also harder to combat.
