The Kavaratti displaces more than 33,000 tons, is about 358 feet long and has a speed of more than 25 knots, the Ministry of Defense reported. As with the previous corvettes, the ship is of Indian design and features a foldable hanger door for a helicopter, a personnel locator system, and a carbon-fiber reinforced superstructure integrated with a steel hull. Design concepts used in building the ASW corvettes include low radar cross section signature through full beam superstructure, inclined ship sides for increased stealth, and a reduced infrared signature through the use of an infrared suppression system for cooling engine and diesel alternator exhausts. The Ministry of Defense said the Kavaratti will equipped with a locally made medium-range gun, torpedo tube launchers and rocket launchers, and a close-in weapon system.
