Pratt & Whitney announced Nov. 23 that it has delivered the 400th F119 engine to the Air Force for the F-22 stealth fighter force. In a company release Nov. 23, Tyler Evans, Pratt’s F119 program director, said this delivery is “tangible proof of the maturity of this fifth-generation engine.” F119s have already accumulated more than 125,000 operational flight hours, he said. Two F119 engines power each F-22. Pratt is using the production and flight experience gleaned from the F119 as it matures the more powerful F135, a powerplant for the F-35 stealth fighter, that uses the F119’s core.
The Space Development Agency added 21 satellites to its nascent data transport network in an Oct. 15 launch, the second mission in a 10-month campaign to field 154 operational spacecraft.
