Rolls-Royce Sending More Power To Navy
Rolls-Royce has received a contract to supply power and propulsion systems for the two latest vessels in the U.S. Navy’s Littoral Combat Ship (LCS) program. Designed to operate in combat zones close to the shore (littoral waters), each LCS will be equipped with two Rolls-Royce MT30 gas turbines powering four large Mk1 axial waterjets. This will allow the vessels to reach speeds in excess of 40 knots, Rolls-Royce said.
This latest order is for ships named Little Rock and Sioux City, and follows previous orders for the Milwaukee and the Detroit, which are both under construction. Rolls-Royce already powers two Lockheed Martin Littoral Combat Ships, the USS Freedom, which was deployed two years early and the Fort Worth, which is due to complete trials later this spring.
The 32 MW MT30 is derived from Rolls-Royce aero engine technology. It also has been selected for the U.S. Navy’s DDG-1000 Zumwalt class destroyer program as well as the UK Royal Navy’s new Queen Elizabeth class aircraft carriers.
The waterjets can pump water at a combined rate of 25 000 gps, enough to fill an Olympic style swimming pool in 25 seconds, according to Rolls-Royce. In addition to gas turbines and waterjets, a range of Rolls-Royce equipment is specified in the Lockheed Martin design, including shaftlines, bearings and propulsion system software.
