GE reçoit 1 B$ pour continuer le développement de son moteur à cycle adaptatif. Un moteur qui promet 20% plus de poussée tout en consommant 25% moins de cartburant, permettant une augmentation substantielle de l’autonomie.
On 24 March 2011, the Department of Defense issued a 90-day temporary stop work order after Congress failed to pass the defense budget. GE declared that it would continue work on the engine program with their own funds in spite of the stop-work order, as allowed in the order and as had been suggested by Schwartz the previous year. However GE is limited to design work only, as the stop-work prevents their use of the existing hardware.
On 12 April 2011, GE reduced its team on project from 1,000 workers down to 100, who will work on the F136 and engine technologies for "future combat aircraft". GE will redeploy the workers to commercial projects, but will not hire the hundreds of new engineers it was expecting. On 25 April 2011, the Department of Defense ended the contract with GE and demanded that the engines built to date be turned over. On 5 May 2011, GE and RR offered to pay for the development through FY2012 and asked for access to the materials. By switching to self funding the cost would reduce from $480 million a year to only $100 million, 60% to be paid by GE and 40% to be paid by RR. After self-funding the project GE and Rolls-Royce announced on 2 December 2011, that they would not continue development of the F136 engine because it is not in their best interest. By then, the six engines had logged more than 1,200 hours of testing since 2009. During the year, GE said that development of the engines was 80% complete; the remaining work would have required US$1 billion in funding
