F-35 program delayed six months due to Pratt & Whitney engine issues, despite $24B in new contracts and 1,300+ aircraft delivered.
The F-35 Lightning II program faces another six-month delay in F135 engine production by Pratt & Whitney, with no official explanation, adding to years of delays and cost overruns.
Despite ongoing challenges, over 1,300 F-35s have been delivered to the U.S. military and 19 allied nations, with the aircraft’s shared design enabling joint operations and logistics.
The Pentagon continues to support the program, approving $24 billion in contracts for 300 new airframes, while planning to finalize Lot 18 and award Lot 19 engine contracts in spring 2026.
