5th Air Force

The 5th Air Force, originally activated as the Philippine Department Air Force in 1941, is one of the oldest air forces in the United States Air Force. It played a crucial role in the Pacific Theater during World War II, notably in the defense of the Philippines, the campaigns in New Guinea, and the liberation of the Philippines. After the war, the 5th Air Force became the primary U.S. air component in Japan and played a major role during the Korean War and the Vietnam War. Today, headquartered at Yokota Air Base, Japan, the 5th Air Force continues to support U.S. interests and regional security in the Indo-Pacific.
