Under a highly classified program, under the development of three decades, 6,000 tons INS Arihant comes under the leadership of Prime Minister Narendra Modi. After successfully completing "redressal patrol", INS Arihant can now be considered as a ballistic missile distribution platform under fully functional water.

He said, "In such an era, a reliable nuclear defense is required." The success of INS Arihant gives a fair response to those involved in nuclear blackmail. "

A ballistic missile submarine is a strategic asset because it is destroying missiles from anywhere in the ocean and has a long time for undiscovered residues. It can roam near the enemy country's edge and can fire ballistic missiles deeply in their area, which otherwise could not reach land-based short-range ballistic missiles.

INS complete India's nuclear test by adding marine strike capacity for Arihant land and air-based distribution platforms. America, Russia, France, China and all the big five nuclear nations in the United Kingdom - already complete nuclear triangle powers. China launched an armed nuclear-powered submarine patrol in 2015.

Last year Pakistan tested its submarine-launch Babur missile and completed its nuclear triangle in the process because it already has ground-based ballistic missiles as well as a tactical atom bomb, which lost its fighter plane Have given.

Defense Minister Nirmala Sitharaman, Home Minister Rajnath Singh and other Union Ministers tweeted to congratulate the Navy and the country on successful patrol of INS Arihant.

India has got the INS Arihant to complete its nuclear test with the first successful prevention patrol. These are in the league of some countries which can design, build and operate strategic strikes nuclear submarines (SSBN).

Rajnath said, "To mark the successful realization of the atomic triangle, successfully congratulating the brave Indian sailors on the INS Arihant to complete their first redressal patrol, this is an important event for India and our strategic and security interests in security. The long way will go. " Lion

Arihant class (Sanskrit for the slayer of enemies) is a class of nuclear-powered ballistic missile submarines for the Indian Navy. They were developed under the US $ 2.9 billion Advanced Technology Vessel (ATV) project for the design and construction of nuclear-powered submarines.

The main vessel of the class, INS Arihant, was launched in 2009 and after the extensive sea trials, the commission was confirmed in August 2016. [8] [9] [10] Arihant is the country's first ballistic missile submarine, built by the country, in addition to the United Nations Security Council of five permanent members. [1 1]

In December 1971, during the Pakistani war of India, US President Richard Nixon sent a carrier warship named Task Force 74, under the leadership of a nuclear-powered USS Enterprise in the Bay of Bengal in an attempt to frighten India.

[12]] [13] In response, the Soviet Union sent a submarine armed with nuclear missiles from Vladivostok to detect the American Task Force. [14] This program demonstrated the importance of nuclear weapons and ballistic missile submarines to then Prime Minister Indira Gandhi.

[15] Following the smiling Buddha nuclear test in 1974, the Naval Headquarters led by Marine Engineering Director (DME) began technical feasibility studies for indigenous nuclear propulsion system (Project 9 32). [16]

The Indian Navy's advanced technology project was designed and built in the 1990's in the shape of a nuclear submarine. [17] Then-Defense Minister George Fernandes confirmed the project in 1998. [18] The initial intention of the project was to design nuclear-powered fast attack submarines,

although in 1998, after the nuclear tests conducted by India on the Pokhran Test Range and Indian pledge, the project was called for the ballistic missile to complete the nuclear triangle In the direction of the design of the submarine was not re-aligned. [19] [20] [21]

Arihant-class submarines are nuclear powered ballistic missile submarines manufactured under the Advanced Technology Vessel (ATV) project. [22] [23] [24] [25] [26] [27] They will be the first nuclear submarine designed and built by India. [28] The submarine is 112 meters (367 feet) long, in which 11 meters (36 feet) beams, 10 meters (33 feet) draft, 6,000 tons (5, 9 00 tall tones, 6,600 short tons) and displacement.

 The depth of 300 meters (980 feet). Supplementary officers are 9 5 officers, including officers and sailors. [29] Boats are operated by a seven-blade propeller powered by an 83-megawatt (111,000-HP) pressure reactor and maximum speed is 12-15 knots (22-28 km / h) and 24 knots (44 Km) / H) immersed. [29]

Four of the submarines launched the tube in their hip and 12 K-15 Sagarika missiles to a warhead (with 750 km or 470 miles) or 4K4 missiles (3,500 km or 2,200 miles). can take. . [30] [31] Submarines are similar to the Akula-class submarine of Russia. [29] Indian Navy will train an Akula-class submarine INS Chakra from Russia in 2012. [32] [33]

Submarines are operated by a pressurized water reactor with highly enriched uranium fuel. [34] [35] A small version of the reactor was designed and built by the Bhabha Atomic Research Center (BARC) at the Indira Gandhi Center for Atomic Research (IGCAR) in Kalpak. [36] This included 42 meters (138 feet) of submarine pressure hut which included a support control panel for water and reactors, a control room,

 as well as an auxiliary control room for monitoring the safety standards of the shielded tank. [37] Prototype reactor became important on 11 November 2003 and it was declared circulated on 22 September 2006.

 [15] Successful operation of the prototype for three years enabled the production version of the reactor for Arihant. [38] [39] The reactor subsystem was tested in the Machinery Test Center in Visakhapatnam. [40] In Burtted submarines, facilities were also set up to load and replace the fuel core of naval reactors. [15]

The detailed designs of the design were implemented at their Hajira Ship Building facility at the Larsen & Toubro submarine design center. [41] Tata Power SED created the control system for the submarine. [42] Integrated steam turbine and related systems were supplied with the reactor by Walchandnagar Industries.

 [43] After the launch of the main ship in July 2009, there was a long and comprehensive process of testing. [44] Propulsion and power system were tested with high-pressure steam tests, followed by submarine testing by its ballast in the post-acceptance tests, limited depth to the tank and controlled dive. [45] The reactors of INS Arihant were critical for the first time on August 10, 2013. [46] On 13 December 2014, the submarine closed for its extensive sea trials. [47] [48]
