"Seventh Air Force was revived under the command of Lt. Gen. Joseph H. Moore to serve Pacific Air Forces during the Vietnam War when the growth of forces required a replacement for the 2d Air Division. In this capacity Seventh Air Force was the Air Component Command of Military Assistance Command, Vietnam (MACV).
Upon reactivation on 28 March 1966, Seventh Air Force was designated a combat command at Tan Son Nhut Air Base, overseeing the operations of the ten primary USAF bases in the Republic of Vietnam. From April 1966 until 1973, the command assumed responsibility for most Air Force operations in Vietnam and shared responsibility with the Thirteenth Air Force for operations conducted from Thailand as 7/13 Air Force.
In June 1966, the first US air attacks near Hanoi and Haiphong occurred when 7AF planes bombed nearby oil installations. The following month, US aircraft struck North Vietnamese forces inside the Vietnamese Demilitarized zone (DMZ).
One of the most publicized battles of the war was the siege of Khe Sanh in early 1968, known as "Operation Niagara." More than 24,000 tactical and 2700 B-52 strikes dropped 110,000 tons of ordnance in attacks that averaged over 300 sorties per day. At night, AC-47 gunships kept up fire against enemy troops. In August 1968, General George S. Brown began to oversee the "Vietnamization" of the air war. By 1970, this effort was successful enough that General Brown released the first USAF units to leave Vietnam.
On 29 March 1973, the command transferred to Nakhon Phanom Royal Thai Air Force Base, Thailand, where it accepted dual responsibility as the US Support Activities Group and Seventh Air Force. As a result, 7AF controlled air assets and operations in Thailand. On 30 June 1975, it was deactivated."
