INS Aridhaman (SSBN 82) (Template:Lit) is a nuclear-powered ballistic missile submarine, and the third of the Indian Navy's Template:Sclass. It is designated S4 Strategic Strike Nuclear Submarine. The 7,000-tonne vessel was built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre in the port city of Visakhapatnam. It is an upgraded variant of the Template:Sclass.[1][2][3]
The submarine, INS Arighaat was quietly launched in 2021 and little has been publicly announced about its capabilities and current status.[4]
Description
The boat will have one seven-blade propeller powered by a Compact Light Water Reactor (CLWR). It can achieve a maximum speed of Template:Convert when on surface and Template:Convert when submerged.[5][6][7] The CLWR is an upgraded form of the one that powers INS Arihant. The CLWR has exceptionally lower acoustic signature than the previous generation making it harder to detect by enemy vessels along with longer endurance.[8]
The submarine has eight VLS tubes in its hump, as compared to four on her predecessors—Template:INS, the lead ship of the class, and Template:INS. She can carry up to 24 K-15 Sagarika missiles (each with a range of Template:Convert), eight K-4 missiles (with a range of Template:Convert) or K-5 missiles (with range of 6,000 km or 3,700 mi).[9][10][11]
Construction and career
INS Aridhaman was launched on 23 November 2021.[12] As of February 2025, the submarine was undergoing trials and was expected to be commissioned in 2025 itself.[13]
On 2 December 2025, the Navy chief, Admiral Dinesh K Tripathi, announced that the submarine had entered the final stages of trials and would be commissioned soon.[14] By late December, the boat had completed sea trials.[15] On 19 February 2026, an NDTV report indicated that the submarine is ready for induction between April and May in the year.[16][17]
The submarine was commissioned on 3 April 2026 by the Defence Minister, Rajnath Singh.[18][19]
