Jetting Through The Seas

Waterjet now standard equipment for U.S. Navy LCS ships

Posted on February 27, 2013

Rolls-Royce has delivered the new Axial Mk1 waterjet for the latest Freedom-variant of the littoral combat ship (LCS) class currently under construction for the U.S. Navy.

Rolls-Royce Axial Mk1 waterjets, providing 22 MW of power, can move almost 1.89 million L/min of seawater. Four of these waterjets will propel the LCS at speeds in excess of 40 knots.

This delivery marks the completion of the Office of Naval Research’s (ONR) Future Naval Capabilities (FNC) program for “Compact, High Power Density Waterjets.” This waterjet will now be standard equipment for all future Freedom variants of the littoral combat ships supplied to the U.S. Navy by Lockheed Martin. 

The waterjets are produced in the United States mainly at Rolls-Royce facilities in Walpole, Massachusetts, U.S.A., and Pascagoula, Mississippi, U.S.A. The underlying design of the Rolls-Royce Axial Mk1 waterjet has also been scaled for other research and development activity within the U.S. Navy.
