Rolls-Royce congratulates US Navy on christening of USS Zumwalt

Rolls-Royce congratulated the US Navy on the christening of the USS Zumwalt, the first of its new and highly sophisticated DDG 1000 multi-mission destroyer class of ship. The 600 foot long all-electric ship was christened by sponsors Ann Zumwalt and Mouzetta Zumwalt-Weathers at Bath Iron Works in Maine during a ceremony attended by thousands of people, including The Honorable Ray Mabus, the Secretary of the Navy, and other dignitaries.

During the ceremony Don Roussinos, Rolls-Royce, President – Naval said: "Rolls-Royce congratulates the US Navy on the christening of its most technologically advanced – and first all-electric – multi mission destroyer class of ship.

"Rolls-Royce is proud to be part of a team that is providing the US Navy with the most efficient and reliable power generation systems for current and future ship programs. Modern multi mission destroyers like the USS Zumwalt DDG 1000 have high power demands, not just for propulsion systems but also for tomorrow's air and missile defense radars, missile systems and directed energy weapon systems. By combining our newly certified MT5S ATGs (auxiliary turbine generator sets) with our well proven MT30 MTGs (main turbine gensets) – the most powerful in the world – Rolls-Royce is able to deliver a highly survivable Integrated Power System that provides 100% of the electrical power
aboard this and future Zumwalt class multi-mission destroyers."

Rolls-Royce scope of supply on the USS Zumwalt includes two Main Turbine Gensets, generating 36MW each, and two Auxiliary Turbine Gensets, generating 4MW each, providing a total of 80 MW for total ship power, in addition to the fixed pitch propellers.

Rolls-Royce recently secured American Bureau of Shipping (ABS) / Naval Vessel Rules (NVR) certification for the MT5S engine and RR4500 genset for use on the USS Zumwalt, becoming the only engine and genset recognized for power generation in this class of US Navy surface combatants.

For future programs the up-rated version of the engine, MT5S-HE+, is under development for use on the DDG 51 Flight III class guided missile destroyers. This will continue Rolls-Royce's position as a key supplier of gas turbine gensets in use on US Navy surface combatants.

The Indianapolis Gas Turbine Group of Rolls-Royce Marine North America led the design effort and conducted the test at the packaging facility, General Tool Company in Cincinnati. The engine is manufactured by Rolls-Royce Corporation in Indianapolis.
