The Air Force and prime contractor Northrop Grumman chose a Pratt & Whitney engine to replace the existing P&W engines on the service’s fleet of 19 E-8 Joint STARS ground surveillance aircraft. A P&W statement called its JT8D-219 propulsion system the “most cost-effective approach.” And, a Northrop release asserted that, over the life of the program, the new engines “will pay for themselves in cost savings” when compared to the cost to maintain the older, existing engines.
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.
