SMITH, Hawaii -- United States Air Force and Marine Corps aircraft joined Japan Air Self-Defense Force and Republic of Korea Air Force aircraft in a sequenced bilateral show of force over the Korean Peninsula September 17, in response to North Korea’s launch of an intermediate range ballistic missile (IRBM) over Japan on September 14. Two B-1B Lancer bombers from Andersen Air Force Base, Guam; four U.S. Marine Corps F-35B Lightning II fifth-generation advanced fighters from Marine Corps Air Station Iwakuni, Japan; four Republic of Korea Air Force (ROKAF) F-15K fighters; and four Koku Jieitai (Japan Air Self-Defense Force) F-2 fighter jets executed this mission. During the mission, U.S. and ROKAF aircraft flew across the Korean Peninsula and practiced their attack capabilities by releasing live weapons at the Pilsung Range training area. The F-35Bs, B-1B bombers and Koku Jieitai fighters flew together over waters near Kyushu, Japan.
