The U.S. Navy is fitting new Rolls Royce water jets to its Littoral Combat Ships (LCS). Originally designed for a cancelled ship program, four of the new Axial-Flow Waterjet Mk-1 engines will be fitted over the next two years to the U.S. Navy’s fifth LCS, USS Milwaukee (LCS-5) at the Marinette Marine shipyard in Wisconsin, with ten of the class to follow.

The new water jets replace earlier commercial jet systems and, according to the Navy, can pump out half a million gallons (1.9 million liters) of high-density seawater per minute, pushing the LCS at over 40 knots (46 mph, 74 km/h) while providing more power for less weight.
