Rolls-Royce has received a modification contract for repair and upgrade of T56 engines, installed on US Navy aircraft.
Under the $35m deal, which follows a previously awarded contract, Rolls-Royce will provide depot-level repair of the T56 Series III engine modules in support of deployed Lockheed Martin P-3 Orion anti-submarine warfare aircraft.
The contract will also support P-3-based aircraft and the T56 engine-powered Lockheed C-130 Hercules and Northrop Grumman C-2A Greyhound aircraft.
Rolls-Royce Defence customer services president Paul Craig said that work under the new option year for a long-term contract to repair and overhaul engines for US Navy aircraft would be performed at Rolls-Royce Engine Services in Oakland, US.
