The Car Nicobar class of high-speed offshore patrol vessels are built by Garden Reach Shipbuilders and Engineers (GRSE) for the Indian Navy.

The vessels are designed as a cost-effective platform for patrol, anti-piracy and rescue operations in India's exclusive economic zone.

INS Kalpeni (T-75) visited the Port of Colombo, Sri Lanka from 19 to 21 October 2024 as a part of Operational Turnaround.

The first two vessels commissioned were initially restricted to speeds up to 27 knots (50 km/h; 31 mph) due to deficiency in the gearboxes, which was later rectified by KPCL.

The mother ship was set ablaze and sank, even as Kalpeni and an Indian Coast Guard patrol vessel, ICGS Sankalp, reached the site.

[25] In another operation on 13 March 2011, an Indian Navy patrol aircraft spotted the Mozambique-registered fishing vessel, Vega 5, when responding to a merchant ship reporting a pirate attack.

Beira-based Vega 5, owned by Spanish company Pescamar Lda, had been captured on 27 December 2010 by pirates who were demanding US$1.8 million in ransom.
