Rolls Royce has won the contract to supply a package of mtu Series 4000 gensets for the lead frigate in the U.S. Navy''s new Constellation class. Construction of the newbuilding is expected to begin at Fincantieri Marinette Marine in Wisconsin later in 2021.
The four high-speed mtu generator sets chosen for this project deliver 3,000 kWe at 1,800 rpm. The gensets are based on the mtu 20V 4000 M53B engine platform and provide a total power output of 12 MW for propulsion and on-board power supply.
Fincantieri Marinette Marine (FMM) was awarded the build contract for the project, which includes the design and construction of the lead ship and the option to build up to 10 ships in total for phase one. A potential planned second phase would include another 10 ships
The Navy Constellation (FFG-62) Class Frigate is a multi-mission warship designed for operation in littoral and blue water environments to conduct air, anti-submarine, surface and electronic warfare. The new Constellation class features a combined diesel electric and gas turbine (CODLAG) propulsion system.
The flexible design engineering of the frigate’s CODLAG propulsion system will allow 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.
