The Air Force has invested $7.5 million to replace the B-52 bomber’s weapons testers—the equipment that certifies the elderly bombers can still release their weapons. The Oklahoma Air Logistics Center at Tinker AFB, Okla., signed a contract with Boeing earlier this year for the work under what’s called the multi-user system tester-armament next generation—MUSTANG—program. MUSTANG will replace three different testers, two of which date from the 1970s, reports the Tinker Take-Off newspaper. Boeing is to complete its work by May 2007.
The U.S. began extensive air and artillery strikes against Islamic State group targets in Syria on Dec. 19 in retaliation for the killing of three Americans on Dec. 13 by a gunman affiliated with ISIS, U.S. officials said.
