Pratt & Whitney’s F135 initial flight test powerplant for the F-35 Joint Strike Fighter has finished successful runs at NAS JRB Fort Worth, Tex., which is near Lockheed Martin’s final assembly plant, according to a company statement. The company says the runs took place at an indoor facility that had been modified to handle the new engine’s 40,000 pounds of thrust—which makes it “the most powerful fighter engine ever built.”
The last remaining T-1 Jayhawk at JBSA-Randolph, Texas, took its final flight to the "Boneyard" at Davis-Monthan Air Force Base, Ariz., on July 15. The 99th Flying Training Squadron will train pilots using T-6 and simulator until it gets T-7 Red Hawk in fiscal 2026.
