Technicians at Arnold Engineering Development Center have begun ground tests on the use of synthetic fuel blend with the B-1B bomber’s F101 engine. Air Force Secretary Michael Wynne was on hand at Arnold AFB, Tenn., to see the first series of tests with the 50-50 mix of Fischer-Tropsch and JP-8 jet fuels. Previously the Air Force has certified the synfuel for use on the B-52 and is working toward certification for the C-17 airlifter. The B-1B engine testing is the “first reach into the supersonic,” said Wynne. Ultimately, the service plans to certify all its aircraft to use synfuel to help offset the high cost of fuel.
Unit commanders are being told to separate service members who can’t shave their cheeks and chin for medical reasons for more than a year, according to new guidance from Secretary of War Pete Hegseth.
