The Navy, which awards all F-35 contracts, has awarded deals to Lockheed Martin and Pratt & Whitney for just over $1 billion, covering long-lead parts, F-35 helmets, and F135 engines.
The F-35’s engine may have parts made from contaminated nickel powder, but the risk to the fleet is considered small, the Joint Program Office and Pratt & Whitney said. Inspections of suspect parts have been made for two years.
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 ...
The Pentagon awarded a contract worth over $2 billion for the next batch of F-35 engines to Pratt & Whitney on June 5. The deal for Lot 17 F135 engines, totaling $2.02 billion, is expected to be completed by December 2025.
Congress should direct the Pentagon to break out the F-35’s propulsion upgrade from the rest of the program to better to track its scope, schedule, and cost, the Government Accountability Office urged in a new May 30 report. Meanwhile, engine-maker Pratt & Whitney added its ...
Lockheed Martin is again delivering F-35s after a three-month hiatus, following a back-to-flight approval on March 8. Investigators continue to plumb the cause of a Dec. 14, 2022 crash and implement a fix to an issue with the F135 engine. The first aircraft delivered after ...
The Air Force couldn't find a place for Adaptive Engine Technology Program powerplants on the F-35 in its fiscal 2024 budget request, opting to harvest what it can from its $4 billion investment and press on to the Next-Generation Advanced Propulsion program.
Lockheed Martin restarted flying operations at its Fort Worth, Texas, facilities March 6, paving the way for deliveries of F-35s to resume after a nearly three-month hiatus. It's not yet clear when the first new F-35 of 2023 will be delivered.
The looming decision on the future of the F-35’s engine—Pratt & Whitney’s F135—has fostered plenty of debate, with some suggesting the F135 should be completely replaced with a new engine through the Adaptive Engine Transition Program (AETP), while others say integrating a new adaptive engine into...
The entire F-35 fleet is slated to get the retrofit engine maker Pratt & Whitney has identified to mitigate the problem that led to suspended deliveries and flight restrictions for some aircraft for nearly two months—a move that will affect hundreds of fighters globally. The decision ...
Pratt & Whitney has developed a fix for F135 engines afflicted with “harmonic resonance,” which should only take 30 minutes per affected engine to correct, company officials said. Deliveries of the engine, which powers the F-35 Lightning II stealth fighter, resumed Feb. 18 after nearly ...
