Rolls-Royce announced yesterday that its Kamewa waterjets have been selected for X-Craft, an experimental high-speed aluminium catamaran. The X-Craft is a demonstrator, which may be used to prove technologies for use in the US Navy`s Littoral Combat Ship (LCS).
Under the contract, awarded by the Titan Corporation, four Rolls-Royce Kamewa 125 SII waterjets will accommodate 50.4MW of power driving the vessel to speeds of up to 50 knots while offering greater manoeuvrability.
The installation of two or more independent units is said to make sideways movement possible, simplifying operations and berthing. Mixed-flow type pumps used in Rolls-Royce Kamewa waterjets reportedly provide more than 90 percent efficiency ratings.
Designed by United Kingdom-based Nigel Gee and Associates Ltd, the X-Craft will be built by Nichols Brothers Boat Builders, Whidbey Island, WA, for the US Navy’s Office of Naval Research (ONR). The waterjets will be built at Rolls-Royce AB, in Kristinehamn, Sweden.
‘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,’ commented Patrick J. Marolda, President of Rolls-Royce Naval Marine.
