US Navy’s new frigate programme – the next generation of small surface combat ships – will have benefit of mtu naval generator sets from Rolls-Royce. These will be a key component of propulsion and on-board power generation for phase one of the US Navy’s Constellation (FFG-62) class frigate programme – previously known as the FFG(X) programme. The Navy Constellation Class Frigate is a multi-mission warship designed for operation in littoral and blue water environments. It will conduct air, anti-submarine, surface and electronic warfare and information operations.

The Rolls-Royce contract for the first shipset provides four mtu naval generator
sets, each rated at 3000 kWe at 1800 rpm. The generator sets are based on the mtu 20V
4000 M53B engine and provide a total power output of 12 MW for propulsion and on-board
power supply.

Adam Wood, Director, Government Sales North America at Rolls-Royce business unit Power
Systems, said: “…We have a legacy of strong support for our partners in both the US Navy and the US Coast Guard, and we are honoured to be selected for (the) FFG-62. There is no doubt that our systems will perform to the high expectations and unique demands of the US Navy Constellation Class.”

According to Rolls Royce, the flexible design engineering of the frigate’s CODLAG (COmbined Diesel, eLectric and Gas) 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.
The lead ship will be nearly 150m in length, accommodate up to 200 sailors and be capable of sustained speeds of more than 26 knots.

Fincantieri Marinette Marine (FMM) of Marinette, Wisconsin (USA), was awarded the build
contract for the project, including the design of the lead ship and the option to build up to 10 ships in total for phase one. A planned second phase could include another 10 ships.
Construction on the first ship is expected to begin later this year.
