-supplied triple type 16V 4000 M90 engines with an output of 2,720kW (3,648BHP) at 2,100 rpm, coupled with ZF 7600 gearboxes and propelled by triple Rolls-Royce Kamewa 71S3NP water jets. This enables the vessels to operate in shallow waters and offers higher speeds and better maneuverability than conventional propellers. The MTU 'Callosum' ship automation system monitors the ship's services that also incorporates fire detection and extinguishing systems. The navigation package was supplied by Northrop Grumman and includes multi-function displays, electronic chart display and information system (ECDIS), autopilot, magnetic compass, and the NAVIGAT 3000 fiber optic gyro-compass. The vessels are equipped with a long-range gun and modern vessel control, navigation, and communication tools. They are capable of 7 days' continuous deployment at sea without replenishing supplies. These FPVs are small in size when compared to other large vessels that Cochin Shipyard has built. Extensive use of aluminum in the superstructure was made to reduce weight, and Cochin Shipyard has developed special techniques to ensure high-quality welding and fabrication of aluminum structures. All the vessels delivered achieved speeds in excess of the contracted speed during sea trials and surpassed the expectations of the Indian Coast Guard with regard to the performance requirements. 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.
