A U.S. Air Force B-1B Lancer prepares to receive fuel from a KC-135 Stratotanker during a mission from Andersen Air Force Base, Guam, into Japanese air space and over the Korean Peninsula, Aug. 31, 2017. After refueling, the B-1Bs with U.S. Marine Corps’ F-35Bs, made contact with two Koku Jieitai (Japan Air Self-Defense Force) F-15J fighters over waters near Kyushu, and then were joined by four Republic of Korea F-15 fighters over the Korean Peninsula. This mission is in direct response to North Korea’s intermediate range ballistic missile launch and emphasizes the combined ironclad commitment to regional allies and partners.
