L&T Gets Additional Orders To Build High Speed Interceptor Boats

Anupama Airy


After the initial order for building 36 interceptor boats for the Indian Coast Guard, L&T is executing additional orders for 18 more boats, totaling 54 orders for construction of a series of high-speed Interceptor Boats (IBs) for the Indian Coast Guard.

Won against stiff global competition, the IBs are designed to meet the stringent requirements of defence and law enforcement agencies, including coastal patrolling, surveillance, high-speed interception and search and rescue operations.



With a length of 27.7 m, breadth of 6.4 m, these are designed with very low draft of 1.3 m.  Twin waterjets powered by diesel engines enable speeds in excess of 45 knots, with a range of over 500 nautical miles.

Constructed of aluminum hull for light weight, these vessels have excellent sea-keeping quality, dynamic stability, maneuverability and acceleration, even at high speeds. Water jet propulsion also provides crash-stop, quick reversal and high speed turning capabilities. The boats can survive up to sea state 6. These unique features set L&T’s interceptors well ahead of other designs.



The Interceptor Boat was designed in-house by L&T at their dedicated Marine Design Centre, equipped with modern integrated digital design aids, including 3D Digital Modelling, Virtual Reality and Product Lifecycle Management.

High end design and analysis software suites were extensively employed in the design and performance analysis of the Interceptor Boat.

All the operational and accommodation spaces have been ergonomically laid out with the use of virtual reality assessments. The machinery compartments are spacious and offer ease of operation.  Excellent performance of IBs in service affirms indigenous design and construction capabilities of L&T for Naval vessels.

L&T has so far delivered 28 nos. IBs so far, with the delivery of last boat approximately two years ahead of contractual schedule, a first of its kind in India. They have been deployed all along the Indian coastline. Further, 20 IBs are ready for delivery to the Indian Coast Guard, awaiting crew placement.

Considering the future requirements, L&T has also developed indigenous waterjet system, a first in India. In addition, L&T has developed a variant of Interceptor Boats with fixed pitch propeller and shafting option in lieu of waterjets, for exports.
