ARNOLD AIR FORCE BASE, Tenn., Nov. 5 (UPI) -- The U.S. Air Force successfully demonstrated the hot-life capability of Pratt & Whitney's F135 engine, the propulsion system for the F-35 Lightning II aircraft.
The test took place at the Arnold Engineering Development Center at Arnold Air Force Base, and focused on conventional takeoff and landing. The Air Force says the demonstration marked a key milestone for the F135 engine, which powers their variant of the Lockheed Martin F-35 multirole fighter jet.
