INS Nistar, the first indigenously designed and constructed Diving Support Vessel, was commissioned into the Indian Navy in the presence of Minister of State for Defence Sanjay Seth in Visakhapatnam on July 18, 2025. The ship, which is the first of the two Diving Support Vessels being built by Hindustan Shipyard Limited, is designed to undertake complex deep sea saturation diving and rescue operations – a capability select Navies possess across the globe.

Sanjay Seth expressed confidence in the capabilities of the Armed Forces, stating that India stands committed and resolute to tackle any form of misadventure from its adversaries. He described the induction of INS Nistar as a technological leap and a milestone in the Indian shipbuilding chapter towards building a future ready force.

Speaking on the occasion, Chief of the Naval Staff Admiral Dinesh K. Tripathi termed INS Nistar as not just a technological asset, but a crucial operational enabler. "Nistar will provide critical submarine rescue support to the Indian Navy as well as our regional partners. This will enable India to emerge as a 'Preferred Submarine Rescue Partner' in this region. The commissioning of Nistar is testimony to the growing capability and maturity of our maritime industrial base, and another shining example of Aatmanirbhar Bharat," he said.
