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 rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
