GSL-class vessels have a length of 52 meters and a beam of 8 meters with a design speed of over 27 knots. These vessels, which will be equipped with state of the art equipment and computerized control systems, are state-of-the-art Fast Patrol Vessels for the Indian Coast Guard. They are based on an GSL's in-house design.[2] The vessels are to be equipped with controllable pitch propeller (CPP)-based propulsion system.[3]
The primary roles of the vessel include fisheries protection and monitoring, patrol within India's exclusive economic zone, coastal patrol, anti-smuggling, anti piracy, and search and rescue operations. The vessels also have a secondary role of providing communication link and escorting convoys during hostilities and wartime.[4]
