The F-35 Joint Program Office has officially announced plans to issue multiple sole-source contracts to Pratt & Whitney to upgrade the fighter’s F135 engine—a widely expected move after Pentagon officials indicated they would do so earlier this year instead of developing an entirely new engine.
New F-35s are coming off the production line with the TR-3 upgrade and going right into storage because testing is incomplete. Next lot negotiations are continuing, but talks over a performance-based logistics contract have stalled.
Little operational impact is expected from contaminated powdered metal used to make high-pressure discs that may have been installed in F-35 fighters, the Joint Program Office said. Any suspect parts will be changed out at depot.
Italy, one of the F-35's biggest international partners, is expanding plans for how to use the fifth-generation fighter—and drawing lessons as it starts development of a sixth-gen aircraft, the Italian Air Force’s top officer said Oct. 12.

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.
It’s hard to know why the F-35 Block 4 upgrade's cost—now $16.5 billion and rising—is going up because it is mixed with the rest of the program, the Government Accountability Office said in a new report.
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 ...
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.
