India will commission its first dedicated nuclear submarine base, INS Varsha, in Andhra Pradesh in 2026 under Project Varsha. It is a secret naval infrastructure project by the Indian Navy, located near Rambilli, 50 km south of Visakhapatnam. The base will boost India’s maritime power in the Bay of Bengal and Indian Ocean Region (IOR) and counter China’s growing presence. INS Varsha will have underground submarine pens, tunnels, and space to dock 12 nuclear submarines safely. Its proximity to Bhabha Atomic Research Centre (BARC) Atchutapuram gives it access to advanced nuclear support.

Notes:
The first tri-service all-women global circumnavigation expedition “Samudra Pradakshina” was flagged off from Mumbai on 7 April 2025 on board the IASV (Indian Army Sailing Vessel) Triveni. It was flagged off by Lieutenant General AK Ramesh, Commandant, College of Military Engineering, at the Indian Naval Watermanship Training Centre, Colaba, Mumbai. The team will sail to Seychelles and return to Mumbai, covering 4,000 nautical miles in 55 days. The expedition is a part of the armed forces’ initiative to promote women’s empowerment, also called Nari Shakti.

Notes:
India successfully tested the Mk-II(A) Laser-Directed Energy Weapon (DEW), joining the US, China, and Russia as one of the few nations with this advanced technology. It is a 30-kilowatt laser-based weapon that can destroy helicopters, swarm drones, radars, and fixed-wing drones with high precision. It is developed by the Defence Research and Development Organisation (DRDO) and its lab Centre for High Energy Systems and Sciences (CHESS), Hyderabad, in collaboration with academic and industrial partners. It uses an Electro Optic (EO) system and radar to identify targets and fires a laser beam to cause structural failure in seconds. This system is fast, accurate, and helps avoid collateral damage, while also reducing the use of costly ammunition in combat.
