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. The class and its vessels are named for Indian islands. They are the first water jet propelled vessels of the Indian Navy. ==Design== The ''Car Nicobar''-class vessels were designed and built by GRSE. Production of the class was fast-tracked after the 2008 Mumbai attacks. The vessels feature improved habitability with fully air-conditioned modular accommodation, on board reverse osmosis plant for desalination, and a sewage treatment plant.〔 The vessels are each powered by three HamiltonJet HM811 water jets, coupled with MTU 16V 4000 M90 engines, delivering a combined of power. An aluminium superstructure reduces weight and is designed to reduce radar cross-section. As patrol vessels, they are lightly armed. They carry various sensors, including the Furuno navigation radar and sonar. Armament on board includes a 30 mm CRN-91 automatic cannon with an electronic day-night fire control system of Ordnance Factory Board (OFB) and Bharat Electronics Limited (BEL) origin. The vessels also mount two 12.7 mm heavy machine guns (HMG) and multiple medium machine guns, besides carrying shoulder-launched Igla surface-to-air missiles to combat aerial threats. The first two vessels commissioned were initially restricted to speeds up to due to deficiency in the gearboxes, which was later rectified by KPCL. INS ''Kabra',' the eighth in the class, has a top speed of more than . The improved manoeuvrability and speed allows these vessels to have high-speed interdiction of fast-moving targets.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Car Nicobar-class patrol vessel」の詳細全文を読む スポンサード リンク
