A U.S. Air Force B-1B Lancer receives fuel from a KC-135 Stratotanker during a 10-hour mission from Andersen Air Force Base, Guam, into Japanese airspace and over the Korean Peninsula, July 30, 2017. After refueling, the B-1s made contact with Japan Air Self-Defense Force F-2 fighter jets in Japanese airspace, then proceeded over the Korean Peninsula and were joined by South Korean F-15 fighter jets. This mission is part of the continuing demonstration of ironclad U.S. commitment to our allies.(U.S. Air Force photo/Staff Sgt. Joshua Smoot)
