PM Modi commissions three indigenous warships — INS Dunagiri, Sanshodhak, Agray — in Kolkata
On June 21, 2026, Prime Minister Narendra Modi commissioned three indigenously designed and built naval ships into the Indian Navy at the Syama Prasad Mookerjee Port in Kolkata: INS Dunagiri, an advanced stealth frigate; INS Sanshodhak, a large survey vessel; and INS Agray, an anti-submarine warfare shallow water craft (ASW SWC). All three were built by Garden Reach Shipbuilders & Engineers (GRSE), Kolkata, with over 75% indigenous content. Modi said India is "no longer just a defence buyer" but a manufacturer and exporter, framing strong maritime capability as a deciding factor for the nation's economic and strategic influence.

Background & Context
Garden Reach Shipbuilders & Engineers (GRSE) is a Kolkata-based defence public-sector shipyard, one of India's premier warship builders. A stealth frigate is a multi-role warship designed with a reduced radar signature; the Project 17A (Nilgiri-class) frigates are advanced follow-ons to the Shivalik class. A survey vessel charts the seabed and waters for safe navigation, while an anti-submarine warfare shallow water craft hunts submarines in coastal waters. India has been pushing indigenisation of defence manufacturing to cut import dependence and build an export base, with the Navy targeting a fully 'Aatmanirbhar' fleet.
