For the U.S. Air Force, fuel efficiency for its fastest warplanes has never been a top priority. Range can be extended with aerial refueling, and guzzling fuel is a small concern when dodging surface-to-air missiles, racing to secure hostile airspace or making bombing runs.

The Air Force is searching for a military engine with dramatically better fuel burn, one that won't sacrifice performance and perhaps will even provide more thrust. Keith Button spoke to the engineers at the Air Force Research Laboratory, General Electric and Pratt & Whitney who have taken up that challenge.
