Adaptive Engine Transition Program (AETP)

A preliminary design review for the F-35 Engine Core Upgrade is scheduled by the end of January, paving the way to start the next phase of development.

Rather than proceeding with a new F-35 engine, the service is using remaining Adaptive Engine Transition Program funds for sixth-generation development.

Speaking at the Global Air and Space Chiefs' Conference, a Pratt & Whitney executive says it has 400 engineers working on a major upgrade for the F135 engine.

A blistering statement attacks Lockheed Martin for continuing to support re-engining the fighter.

A persistent and worsening cooling system shortfall is finally being addressed in a new upgrade package now being defined by the Joint Program Office.

A new audit report blames a cooling system flaw that Lockheed Martin discovered 15 years ago for a problem that could cost $38 billion in extra repair bills.

A rare tour of GE’s test chamber for adaptive engines highlights the reality of the new technologies as the company tries to save the program from cancellation.
