EAST HARTFORD, Conn., Feb. 3 (UPI) -- U.S. company Pratt & Whitney announced a milestone achievement for its F135 engine program following the first delivery of a production engine.
The Pratt & Whitney F135 propulsion technology was designed for the F-35 Lightning II stealth aircraft, a single engine fighter aircraft being developed by Lockheed Martin for the United States and eight other partner countries.
Pratt & Whitney says the delivery of the first F135 production engine to the F-35 team, which follows more than 13,000 hours of testing, marks a milestone for the next-generation engine system.
"The F135 engine program accomplishments and this initial production delivery milestone demonstrate we are continuing our legacy of fielding the most advanced military jet engine technology to the benefit of the warfighter," Warren Boley, F135 engine programs vice president, said in a statement.
"The F135 engine has reached a level of maturity after 13,000 hours of successful testing, building on heritage of the proven F119 engine powering the F-22."
