U.S. Air Force B-1B Lancers, U.S. Marine Corps F-35B Lightning IIs and Japan Air Self-Defense Force F-2 fighters fly in formation during a show of force, north of Japan, Sept. 17, 2017. The flight took place in response to a North Korean test-launch of an intercontinental ballistic missile over the northern Japanese island of Hokkaido last Friday. The formation illustrates the ironclad alliance the U.S. maintains with allies and partners in the Indo-Asia-Pacific. (U.S. Air Force photo by Capt. Mike Karnes)
