The US Department of Defense (DoD) Naval Air Systems Command (NAVAIR) has awarded a contract to Rolls-Royce to provide support for the F405 engines that power the US Navy’s T-45 training aircraft.

The US Navy has exercised the third-year option of the contract to provide guaranteed engine availability under the base contract signed in 2008.

Under the $99.9m contract, Rolls-Royce will provide maintenance, support, troubleshooting services as well as supply parts and logistics for the F405 engine and the aircraft gas turbine starting system.

The company will also provide propulsion services for more than 200 aircraft currently operating at four main naval air stations.

Work is expected to be completed in September 2012.
