Rolls-Royce has been awarded a $35 million contract extension for repair and overhaul of T56 engines on US Navy aircrafts.
The services contract covers depot-level repair of the T56 Series III engine modules to support fielded P-3 Orion and derivative aircraft, as well as T56-powered Lockheed Martin C-130 Hercules and Northrop Grumman C-2A Greyhound airlifters.
The repairs will be carried out at Rolls-Royce Engine Services at Oakland, US (RRESO). In addition to T56 repair and overhaul, RRESO services AE 1107C(V-22 Osprey), F405 and M250 engines for other military customers.
The 4591 shp T56-A Series III is a single shaft, modular design, turboprop engine with a 14-stage axial flow compressor driven by a four-stage turbine unit.
Since the engine entered production in 1954, over 18,000 T56/501-D turboprops have been installed on a wide variety of propeller-driven aircraft, including Lockheed Martin's ubiquitous C-130 Hercules and L-100 transports, Northrop Grumman's E-2 Hawkeye early warning aircraft and Lockheed's P-3 Orion anti-submarine warfare aircraft.
The Convair 580 and Lockheed Electra are still in commercial passenger and cargo service around the world.
