U.S. Navy’s XCraft Delivered
The United States Navy recently accepted the new Catamaran Sea Fighter (FSF-1), also known as the X-Craft. The catamaran is 80 meters long, weighs 960 tonnes and was built by Nichols Brothers Boat Builders on Whidbey Island, Washington, U.S.A. The ship is equipped with an integrated drive system who’s main drive components came from MTU Detroit Diesel - these include the engines and transmission and the monitoring and control system.
The engines are twin MTU 16V 595 diesels and two GE LM2500 gas turbines integrated into a CODOG arrangment. This is a new first for the US Navy, which has previously only used gas turbines or pure-play diesel propulsion. With the diesel engines, the X-Craft has a range of 4000 sea miles at a travel speed of 20 knots. The main drive components are integrated via an MTU RCS-5 CODOG/WJ remote control system that includes a three-axial joystick control system. MTU also supplied the entire MCS-5 type 2 ship automation system communicating via a fiberoptic high-speed databus.
