L&T fast interceptor craft are a series of high-speed interceptor boats being built by L&T Shipyard for the Indian Coast Guard. The ships are intended for patrol and rescue operations in India's Exclusive Economic Zone.


The interceptor boats are of planing-type, designed by the L&T Marine & Ship Design Division, an in-house facility of Larsen & Toubro Limited. They are 30 metres long with 90 tonnes displacement and can achieve a maximum speed of 45 knots. The interceptor boats has full aluminium-alloy hull for reduced weight and is powered by twin water-jet propulsion systems to enable quick response. The vessels are fitted with state-of-the-art navigation and communication equipment and medium-range armament. Each vessel is powered by two Caterpillar Marine Power Systems 3516C marine propulsion engines (2525 bkW @ 1800 rpm, ‘D’ Rating) and two C-4.4 auxiliary generator sets (86 eKW @ 1500 rpm). The water-jets for the high-speed interceptor boats are being supplied by MJP Waterjets. Delivery of the water-jets began in 2010 and will continue until 2013.[1] They are also fitted with MARIS ECDIS900 SmartLine Mk10 Flat Panel Computer with radar kit.[2]

The vessel's crew consists of one officer and eleven personnel and are designed to perform coastal surveillance, search and rescue, anti-smuggling and anti-poaching operations in close coast and can also operate effectively in shallow water.


M/s L&T secured an order on 22 March 2010 for building 36 high speed interceptor boats for Rs 977 crores.[3] It further secured an additional order on 22 January 2013 to produce 18 similar Interceptor boats for Rs 447 crore.[4] The boats are planned to be constructed at L&T’s existing shipyard at Hazira and at its new up-coming Kattupalli Shipyard near Ennore.

ICGS C-401, the first of the series was commissioned at Porbandar by Air Marshal A.K. Gogoi, Air Officer, Commanding-in-Chief South Western Air Command on 20 December 2012.[5] Its first deployment is at Mundra under the administrative and operational control of the Commander Coast Guard (North-West) region and commanded by Deputy Commandant Lakshya Sharma.
