The Air Force wants to spend $1.3 billion to finish designing two competitive engines to power the Next-Generation Air Dominance fighter, budget documents show. They say the designs are well along, and the timing of the request indicates production could begin by 2028.
The engines for the hyper-secret Next Generation Air Dominance fighter will be a different size than the adaptive engines developed for an F-35 upgrade, but many of the technologies will “port over” to the new powerplant, the Air Force’s propulsion czar told reporters Aug. 1.
“The F-35 is the most advanced fighter yet built, but decisions and compromises imposed on it more than a decade ago continue to push up its cost, decrease its reliability, limit its performance, and constrain its ability to exploit new technologies. For fighter pilots of ...
The F-35 Joint Program Office is sticking by its endorsement of Pratt & Whitney’s Engine Core Upgrade (ECU) for the F135 powerplant, saying the improvement will meet all the fighter’s future needs for power. But it declined to weigh in on the increasingly combative war ...
F-35 maker Lockheed Martin thinks the Pentagon should reverse course and pursue the more expensive but technologically advanced Adaptive Engine Transition Program (AETP) for future versions of the fighter, rather than the more incremental F135 Engine Core Upgrade chosen by the Air Force in its ...
Pratt & Whitney would like to keep its monopoly on supplying powerplants for the F-35 fighter fleet and is pushing for the government to choose an upgrade of the F135 engine instead of an all-new adaptive engine, which it said would be far more costly ...
The Pentagon will soon decide whether to move ahead with a new engine for the F-35, and officials won’t simply table the issue indefinitely, Defense Department acquisition and sustainment chief William LaPlante said at an acquisition conference. He also said calls to break up the ...
Lockheed Martin suggested the long-term sales prospects for the F-35 are uncertain amid worries DOD may begin to pivot away from the program.
Nearly 50 members of Congress have urged Defense Secretary Lloyd J. Austin III to fund a new phase of development for advanced fighter engines in the fiscal 2024 budget, sending a letter to the Pentagon on Oct. 7. The letter, signed by 49 lawmakers from ...
GE Aviation announced that it completed milestone tests for the engine it hopes will power Air Force fighters well into the future. GE calls its offering in the Adaptive Engine Transition Program the XA100, and the company hopes the Air Force will soon select it ...
The Air Force propulsion program tasked with producing engines for the Next Generation Air Dominance fighter awarded contracts to a mix of engine makers and aircraft builders Aug. 19, hinting that integration could be a priority in the prototyping process. GE Aviation, Pratt & Whitney, ...
GE’s AETP offering, called the XA100, delivers 25% better fuel efficiency, twice the thermal management capacity, and at least 10% more thrust than the existing F-35 engine. The XA100’s three test campaigns—including one currently taking place at the Air Force’s Arnold Engineering Development Complex (AEDC)—have ...
