Program Moving Closer To Production Aircraft

Pratt & Whitney has delivered its final Conventional Take Off and Landing/Carrier Variant (CTOL/CV) F135 flight test engine to the F-35 Joint Program Office, completing another step as the program transitions from System Development and Demonstration to production.

"I am tremendously proud of the Pratt & Whitney F135 team who has worked so tirelessly over the last eight years, in partnership with the F-35 Joint Program Office and Lockheed Martin, to get to this significant point in the F135 program," said Warren Boley, Vice President of F135 Engine Programs. "This final CTOL/CV F135 engine delivery is another demonstration of the continued maturing of this engine program, which has logged more than 12,850 test hours and will begin production engine deliveries later this month."

Pratt & Whitney has delivered 17 flight test engines and expects to deliver the final Short Take Off and Vertical Landing (STOVL) flight test engine early this year.

"What makes this milestone even more exciting is that it signifies a transition from development activity to production, as we are poised to deliver our first production CTOL/CV F135 engine within several days of delivering this final CTOL flight test engine," Boley said. "We are proud to continue successfully powering the F-35 Lightning II flight test program, and our eyes are also trained on the day when our first production F135 CTOL engine will be installed in a production F-35 and delivered to our military men and women."
