S5 is the code name for a planned class of Indian nuclear-powered ballistic missile submarines currently being developed for the Indian Navy. S5 will weigh around twice as much as the preceding Arihant-class submarine. It is expected to start production by 2027.[6]

Design
The S5-class of submarines are planned to weigh around 13,500 tonnes (13,300 long tons; 14,900 short tons).[7] The submarines are planned to be armed with up to twelve or sixteen K6 Submarine-launched ballistic missiles, each armed with multiple independently targetable reentry vehicles.[1][5]
Development
The Government of India made an assessment of India's capability to design and construct a class of three new ballistic missile submarines codenamed S5 in 2006 when it was realised that the reactor and payload capacity of the Arihant-class submarines was limited. These submarines were initially planned to be operational beginning in 2021 but were delayed. The delay prompted the Indian Government to sanction an additional Arihant-class submarine in 2012 to avoid the production line becoming idle.[1]
As of 4 December 2022, the S5-class submarine was to enter production by 2027.[6][8]
As of September 2024, the design phase of the submarine was nearing completion and project sanction was expected soon.[9]
In September 2025, the Times of India reported that the Bhabha Atomic Research Centre (BARC) is developing a 200 MWe-rated nuclear reactor for the Indian Navy's next-generation nuclear submarines, including Project 77 and S5-class submarines.[10]
