Munitions from a U.S. Air Force, U.S. Marine Corps and Republic of Korea Air Force (ROKAF) bilateral mission explode at the Pilsung Range, South Korea, Sept 17, 2017. The U.S. and ROKAF aircraft flew across the Korean Peninsula and practiced attack capabilities by releasing live weapons at the training area before returning to their respective home stations. This mission was conducted in direct response to North Korea's intermediate range ballistic missile launch, which flew directly over northern Japan on September 14 amid rising tension over North Korea's nuclear and ballistic missile development programs.
