Weapons School Integration: Operation Instant Thunder
A KC-135 Stratotanker refueling aircraft, assigned to the 509th Weapons Squadron at Fairchild Air Force Base, Wash., prepares to refuel an F-16 Fighting Falcon fighter jet during a Weapons School integration mission over the Nevada Test and Training Range, June 8, 2017. At the conclusion of nearly 400 hours of graduate-level academics and combat training missions, the Weapons School course climaxes with a week-long exercise, known as Weapons School Integration.
