INS Arighat is an upgraded variant of the Arihant-class submarine. [12] [13] [14] It is the second nuclear-powered ballistic missile submarine being built by India [15] under the Advanced Technology Vessel (ATV) project to build nuclear submarines at the Ship Building Centre in Visakhapatnam. [1] It has the code name S3. [3] [16] [17]

The submarine was quietly launched in 2017 and little has been publicly announced about its capabilities and current status. The submarine was originally known as INS Aridhaman but was renamed INS Arighat upon its launch. According to reports released in early 2021, she was to be commissioned in late 2021 alongside INS Vikrant. [18]

Description

The boat will have one seven-blade propeller powered by a pressurised water reactor. It can achieve a maximum speed of 12–15 knots (22–28 km/h) when on surface and 24 knots (44 km/h) when submerged. [19] [ better source needed ]

The submarine has four launch tubes in its hump, just like her predecessor. She can carry up to 12 K-15 Sagarika missiles (each with a range of 750 km or 470 mi), or four of the under-development K-4 missiles (with a range of 3,500 km or 2,200 mi). [3] [20]

Status

She was outfitted in December 2010, it was announced by the navy officers that she would be launched in mid or late 2011. In the event, years of delay ensued and, in October 2017, it was reported that she would be launched in November or December and would undergo outfitting. [21] The launch took place on 18 October 2017.[ citation needed ]Arighat was expected to be commissioned in 2021. [3] [22] As of October 2022, INS Arighat was undergoing harbour trials and was slated to be commissioned in 2022. [23] [18] INS Arighat has not been commissioned as of 5 February 2023, and an official commissioning date has not been announced. [24] A report in the Hindustan Times states that INS Arighat will be commissioned in 2024. [25] [26]

A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect, thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of ballistic missile submarines is dominated by the United States and Russia. Smaller numbers are in service with France, the United Kingdom, China and India; North Korea is also suspected to have an experimental submarine that is diesel-electric powered.

Sagarika, also known by the code names K-15 or B-05 or PJ-08, is an Indian submarine-launched ballistic missile (SLBM) with a range of 750 kilometres (466 mi) that was designed for retaliatory nuclear strikes. It belongs to the K Missile family and forms a part of India's nuclear triad.

<i>Arihant</i>-class submarine Class of Indian nuclear-powered ballistic missile submarines

The Arihant-class is a class of Indian nuclear-powered ballistic missile submarines being built for the Indian Navy. They were developed under the ₹900 billion (US$11 billion) Advanced Technology Vessel (ATV) project to design and build nuclear-powered submarines. These vessels are classified as 'strategic strike nuclear submarines' by India.

INS <i>Arihant</i> Indian nuclear powered submarine

INS Arihant, designated S2 Strategic Strike Nuclear Submarine, is the lead ship of India's Arihant class of nuclear-powered ballistic missile submarines.

INS Varsha is a new naval base being developed under Project Varsha for the Indian Navy. This base will be the home of the navy's new fleet of nuclear submarines and ships. It was planned to be located within a radius of approximately 200 kilometres from Visakhapatnam, the headquarters of the navy's Eastern Naval Command. Previous news reports suggested that Gangavaram had been the initial site for the new base. The base is now being developed at Rambilli, which is 50 km from Visakhapatnam.

<span class="mw-page-title-main">K Missile family</span> Indian ballistic missile

The K family of missiles, is a family of submarine-launched ballistic missiles (SLBM) developed by India to boost its second strike abilities and thus augment its nuclear deterrence. Information about this family of missiles has mostly been kept classified. It is reported that 'K missiles' are faster, lighter and stealthier than their Agni missile counterparts. High Energy Materials Research Laboratory (HEMRL) developed a new formulation of composite propellant that is more efficient and provide greater thrust compare to Agni missile series. The objective behind the development is to make K missile family faster and lighter without compromising on operational range.

USHUS is an integrated sonar system developed by the Naval Physical and Oceanographic Laboratory (NPOL) of the Defence Research and Development Organisation (DRDO), India, for use in submarines of the Indian Navy. It is primarily designed to be used in Sindhughosh class submarines, though it is reported to be fitted in the Arihant-class nuclear-powered ballistic missile submarines as well. USHUS is reported to be superior to its Russian equivalents.

INS <i>Vikrant</i> (2013) Indian Navy aircraft carrier

INS Vikrant is an aircraft carrier in service with Indian Navy. The carrier is India's fourth carrier and the first to be built in India. It was constructed by the Cochin Shipyard Limited (CSL) in Kochi, Kerala. The namesake Vikrant is a tribute to India's first aircraft carrier INS Vikrant (1961). Vikrant means "courageous" in Sanskrit. The motto of the ship, "जयेम सम् युधिस्पृधः" (Sanskrit), means "I defeat those who dare to challenge me" (English). It is currently one of two active aircraft carriers in the Indian Navy, the other being the flagship INS Vikramaditya.

The Indian Navy has been focusing on developing indigenous platforms, systems, sensors and weapons as part of the nation's modernisation and expansion of its maritime forces. As of November 2023, the Indian Navy has 67 vessels of various types under construction including destroyers, frigates, corvettes, conventional-powered and nuclear-powered submarines and various other ships. It plans to build up to a total of 200 vessels and 500 aircraft by 2050. According to the Chief of the Naval Staff's statement in December 2020, India has transformed from a buyer's navy to a builder's navy.

The Indian Navy aims to procure new nuclear-powered attack submarines under Project 75 Alpha. The Government of India approved the construction of six of such submarines in February 2015. These will be designed by the Navy's in-house Directorate of Naval Design and built in India at the Shipbuilding Centre at Visakhapatnam. The construction is expected to commence on 2023-24 while the first submarine is expected to enter service in 2032.
