Rolls-Royce will jet propel Navy’s X-Craft catamaran

Rolls-Royce has announced that its Kamewa waterjets have been selected for X-Craft, an experimental high-speed aluminum catamaran. The X-Craft is a demonstrator that may be used to prove technologies for use in the US Navy’s Littoral Combat Ship (LCS). Under the contract awarded by prime contractor The Titan Corporation, four high-efficiency waterjets will accommodate 50.4MW of power, driving the vessel to speed’s of up to 50 knots while offering greater maneuverability. The installation of two or more independent units makes sideways movement possible, simplifying operations and berthing.

Designed by United Kingdom-based Nigel Gee and Associates, the X-Craft will be built by Nichols Brothers Boat Builders, Whidbey Island, WA, for the US Navy’s Office of Naval Research (ONR), and will be evaluated for advanced hydrodynamic performance, structural behavior, and propulsion systems efficiency of high-speed hull form technologies. The vessel measures approximately 73 meters in length.

“Rolls-Royce is the foremost leader in the research, development and manufacture of high-power waterjets. We are pleased to have the opportunity to showcase large waterjets to the US Navy,” said Patrick J. Marolda, president of Rolls-Royce Naval Marine Inc.

The waterjets will be built at Rolls-Royce AB, in Kristinehamn, Sweden, the sole industry facility equipped with a full marine laboratory to support ongoing research and product development.
