Rolls-Royce to supply generator sets for US Navy’s frigate
The Power Systems division of Rolls-Royce has been selected to supply a further four of its mtu naval generator sets for the USS Congress (FFG-63), the second ship in the U.S. Navy’s Constellation Class Guided-Missile Frigate program, previously known as the FFG(X) program.
As informed, Rolls-Royce has made significant investment at its production facilities in Aiken, S.C. and Mankato, Minn. to support the program and manufacture the gensets in the US.
The company is currently supplying mtu gensets for the lead ship in the Constellation Class program, the USS Constellation (FFG 62), relying on its established team in Friedrichshafen, Germany, to fulfil the project.
For the second ship, the FFG-63, the company has successfully transferred advanced technology and detailed manufacturing processes to the US.
The USS Congress (FFG-63) is a multi-mission warship designed for operation in littoral and blue water environments to conduct air, anti-submarine, surface and electronic warfare, in addition to information operations.
The four generator sets, each rated at 3000 kWe, are based on the proven and most power-dense mtu 20V 4000 M53B engine and will provide a total power output of 12 MW for propulsion and on-board power supply.
Fincantieri Marinette Marine (FMM) of Marinette, Wisc. was awarded the construction contract for the project.
The completed vessel will be powered by a combined diesel-electric and gas turbine, allowing for energy-efficient diesel power generation for propulsion at normal cruising speeds with extended range, while enhancing anti-submarine capability in its extremely quiet diesel-electric configuration.
When completed, the ship will be nearly 500 feet in length, accommodate up to 200 crew and be capable of speeds in excess of 26 knots, with a range of 6,000 nautical miles at 16 knots.
