The Allison T56 is an American single-shaft, modular design military turboprop with a 14-stage axial flow compressor driven by a four-stage turbine. It was originally developed by the Allison Engine Company for the Lockheed C-130 Hercules transport[3] entering production in 1954. It has been a Rolls-Royce product since 1995 when Allison was acquired by Rolls-Royce. The commercial version is designated 501-D. Over 18,000 engines have been produced since 1954, logging over 200 million flying hours. 

The T56 turboprop, evolved from Allison's previous T38 series,[5] was first flown in the nose of a B-17 test-bed aircraft in 1954.[5] One of the first flight-cleared YT-56 engines was installed in a C-130 nacelle on Lockheed's Super Constellation test aircraft in early 1954.[6] Originally fitted to the Lockheed C-130 Hercules, the T56 was also installed on the P-3 and E-2/C-2 aircraft, as well as civilian airliners such as the Lockheed Electra and Convair 580.[5]A major setback occurred when a T56-A-1 engine delivered to Lockheed in May, 1953, produced only 3,000 hp, not the required 3,750 shp needed for the C-130. A further setback occurred in August 1953 when an engine being tested failed after only 6 ½ hours run time. A redesign of the engine failed during testing in September of the same year. A second redesign was more successful. Evolution of the T56 has been achieved through increases in pressure ratio and turbine temperature. The T56-A-14 installed on the P-3 Orion has a 4591 shp rating with a compression ratio of 9.25:1 while the T56-A-427 fitted to the E-2 Hawkeye has a 5250 shp rating and a 12:1 compression. In addition, the T56 produces approximately 750 lbs of thrust from its exhaust.[7]A marinised turboshaft version, the 501K engine, is used to generate electrical power for all U.S. Navy cruisers and destroyers currently in commission.[4]An engine enhancement program to reduce fuel consumption and decrease temperatures was approved in 2013, and the US Air Force expects to save $2 billion and extend the C-130 fleet life.[8]The Lockheed Martin C-130J Super Hercules which first flew in 1996, has the T56 replaced by the Rolls-Royce AE 2100, which uses dual FADECs (Full Authority Digital Engine Control) to control the engines and propellers.[9] It drives new six-bladed scimitar propellers from Dowty Rotol.
