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.

Design

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 aluminum-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.

Orders

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 were constructed at L&T's existing shipyard at Hazira and at Kattupalli Shipyard near Ennore.

Commission and deployment

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.

The second vessel of the class, C-402, was commissioned at Mumbai Naval Dockyard on 12 April 2013,[6] followed by C-403 at Mundra on 11 August 2013,[7] and C-404 at Beypore on 6 December 2013.[8] The ICGS C-421 was commissioned on 21 September 2015 at Androth (L&M Islands) commanded by Deputy Commandant Rohit Kulkarni.[9] The ICGS C-422 was commissioned at the Karaikal Port on 28 November. The vessel will patrol the coastal areas of Tamil Nadu, along the Bay of Bengal.[10] C-405 was donated to the Seychelles Coast Guard in February 2016 and recommissioned as SCGS Hermes.[11]

On 29 July 2019, the government of India donated two vessels of the class to Mozambique Navy.[12]

All 36 boats ordered in the first batch were commissioned by January 2020.[13]
