The waterjet propulsion system is one of the most effective systems for littoral water operations. L&T waterjets have been developed to meet stringent operational demands for naval and coast guard vessels. It adds the critical dimension of high speed for defence operations. The system is designed for good maneuverability, efficient operation as well as improved shallow-water operation. The in-built steering and braking systems make the design compact. We provide customised mixed and axial flow waterjet solutions to suit the ship's operational requirements.
