( Log Out /  The starboard side consists of two rectangular vents that draw in water when the submarine submerges into sea. The PWR was developed by the Bhabha Atomic Research Centre with assistance from a Russian design team. The K-4 has a longer range of 3,500 km (2,200 mi) and has commenced trials.[29][30][31]. India tested its first weapon, an eight-kiloton device nicknamed Smiling Buddha, in 1974. Arihant is expected to enhance the Indian Navy’s capability of delivering nuclear weapons from all terrains.

It will carry 12 K-15 SLBMs that can be launched even under ice caps. The final phase of the trials will include weapon trials. INS Arihant … It is the smallest ballistic-missile submarine in the world, with the possible exception of the North Korean Gorae class. At either rate, the submarine is estimated to be 330 to 360 feet long, with submerged displacement of 6,500 tons. [38] It was also expected that the duplication of India's land based reactor, integration of systems, and sea trials are expected to take three to five years.[39].

INS Arihant (SSBN 80) [7] (Sanskrit: Vanquisher of Enemies), designated S2 Strategic Strike Nuclear Submarine, [8] is the lead ship of India's Arihant class of nuclear-powered ballistic missile submarines. Tata Power Strategic Engineering Division (SED) built the control systems for the submarine. Walchandnagar Industries, a company specialising in execution of heavy engineering projects, designed parts of the steam turbine. [37] The launch of Arihant strengthens India's endeavour to build a credible nuclear triad – the capability to fire nuclear weapons from air, land and sea. [52] This marked the completion of India's nuclear triad. The crew of Arihant will be trained on the 12,000t Akula-II submarine. [22] A land-based prototype of the reactor was first built at Kalpakkam and made operational in September 2006. While the air component is fulfilled by the Mirage 2000 fighter-bomber and the land-based component by the Agni system, the new Arihant-class submarine has been indigenously developed for form the final point of the triangle. It was jointly developed by the Indian Navy, Bhabha Atomic Research Centre (BARC) and Defence Research and Development Organisation (DRDO) at the naval dockyard in Visakhapatnam. The Destruction of Army Group Center, 1944. It is being built under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam. During these trials actual firing of submarine-launched ballistic missiles (SLBM) will take place from the platform.

New Delhi: Defence Minister Manohar Parrikar today flagged off first Made-in-India nuclear-powered submarine INS Arihant from Vizag for sea trials. The propulsion plant housing the reactor is 42m long and 8m in diameter. nuclear-powered submarine – the INS Arihant, which Prime Minister Manmohan Singh launched for sea trial in Visakhapatnam on 26 July 2009. Arihant will be taken for a series of high-speed runs during the sea acceptance trials and its various components will be tested at different depths, temperatures and pressure. India is believed to have 520 kilograms of plutonium—enough for, according to the Arms Control Association, “100 to 130 warheads.” New Delhi describes this a “credible minimum deterrent” against neighboring nuclear powers China and Pakistan. It also consists of a pressure vessel built from unique steel, a control room as well as an auxiliary control room. It also features an underwater communications system. Two more units, the S4 and the S4*, will be inducted by 2025. The name Arihant derives from two words – Ari meaning enemy and Hanth meaning destroy.

Combat Fleets of the World claims it is based on the Akula, and lengthened an additional thirty feet to accommodate a missile compartment. These submarines are a part of India’s nuclear triad, classified as Strategic Strike Nuclear Submarines. Indian Navy’s project to build nuclear-powered attack submarines (SSNs) is before the Cabinet Committee on Security (CCS) for approval. Nuclear-powered submarines, on the other hand, can stay under water for long durations without being detected. And, in the logic of nuclear deterrence strategy, an invulnerable nuclear arsenal makes for an invulnerable country. [40] On 27 January 2013, Sagarika, the primary armament of Arihant, completed its final developmental test and was later integrated with the submarine. By 1995, ship-sized reactor trials were underway at the Bhabha Centre in Mumbai. To reduce the weight of the plant, light water and enriched uranium was used as opposed to non-enriched uranium used in land-based reactors. The submarine’s exterior is uneven and the hull is placed on a mat covered with tiles.
