Despite threats from budgetary buzzards, Joint Strike Fighter development continues, with Pratt & Whitney reporting that it has completed the first flight-test engine that will power the F-35 next year. P&W has been the lead propulsion system on the JSF since the concept demonstration phase in 1996, and the completed engine—the F135—is an evolved version of the F119 engine used on the F/A-22. P&W says engines will go on the test F-35 fighter early next year, with test flights scheduled for late summer 2006.
The KC-Z4, a blended wing body tanker concept being developed by startup JetZero, could fuel larger groups of aircraft at longer range to hold more targets at risk, company officials say.
