Description: The F136 engine is being developed, jointly by Rolls-Royce and General Electric, as one of two propulsion systems for the F-35 Joint Strike Fighter. Two alternative propulsion systems are required to power the F-35 as it was in the case of the highly successful F-16 fighter. General Electric Aircraft Engines owns 60 percent of the F136 program and will develop the core compressor and coupled high-pressure/low-pressure turbine system components, controls and accessories, and the augmentor. Rolls Royce is responsible for the remaining 40 percent and will take care of the front fan, combustor, stages 2 and 3 of the low-pressure turbine, and gearboxes. Other international participant countries will develop and manufacture F136 components.

The F136 engine is a derivative of the F120 which lost the F-22's propulsion contract versus the Pratt & Whitney F119 engine. The F136 CTOL will power the US Air Force and US Navy F-35 variants operating from air force bases and aircraft carriers respectively.

The first F136 CTOL engine completed testing in December 2004 at the GE's facility in Evendale, Ohio. General Electric expects to get a new SDD multi-year contract in 2005 from the JSF program office. First full SDD-compliant F136 would be available in 2007 with the first production engine scheduled for 2011.

On 23 August 2005, the US government awarded General Electric Rolls Royce team a contract valued at $2.4 billion for the F136 engine System Development and Demonstration (SDD). The contract funds will expire in September 2013 and the first F136 would achieve Initial Operational Capability (IOC) powering the F-35 stealth fighter in 2012. F136 engine flight testing on the F-35 was slated to begin in 2010.

As part of fiscal year 2007 budget the Department of Defense conceded the termination of F136 engine development to obtain further cost savings. The United States Department of Defense approved the development of two power plants (F135/F136) for the F-35 aircraft following the experience accumulated during the F-16 program which was also powered by two alternative engines (F100/F110). Actually, current fighter-aircraft engines provide high reliability allowing to avoid the dual engine solution. During the cold war the major concern to proceed with a two alternative power plants approach was the fear to have to ground the entire F-16 fleet due to flaws in the engine's design.

The United States cut the funding for the F136 engine development in July 2009 along with the termination of the F-22 stealth fighter procurement program to provide more funds for the F-35/F135 aircraft/engine development. The Pentagon issued a stop work order on the F136 engine program on March 24, 2011. The F136 extra engine program was officially terminated by the Department of Defense (DoD) on April 25, 2011.
