India launched its fourth nuclear powered ballistic missile (SSBN) submarine at Ship Building Center (SBC) in Visakhapatnam this week to strength its nuclear deterrence against its adversaries.

• India’s second SSBN INS Arighaat was commissioned by Defence Minister Rajnath Singh on August 29, 2024.
• Third SSBN INS Aridhaman will be commissioned next year.
• On October 9, the Cabinet Committee on Security (CCS) cleared the Indian Navy’s plans for construction of two nuclear powered attack submarines to deter any adversaries in the Indo-Pacific.
• The newly launched S4* SSBN has nearly 75% indigenous content and is equipped only with 3,500km range K-4 nuclear ballistic missiles, which can be fired through vertical launching systems.
