Seventh/Thirteenth Air Force
military unit

Seventh/Thirteenth Air Force was an operational headquarters that controlled United States Air Force tactical combat operations from Thailand during the Vietnam War. It was established in 1966 when Seventh Air Force replaced the 2d Air Division as the USAF headquarters in South Vietnam and was discontinued in 1973, when Seventh Air Force moved its headquarters from Vietnam to Thailand. Its combat units were attached to it for operations, but were assigned to Thirteenth Air Force in the Philippines for administration.
History
Seventh/Thirteenth Air Force (7th/13th) was organized in April 1966 at Udorn Royal Thai Air Force Base, Thailand. It was assigned to Thirteenth Air Force at Clark Air Base in the Philippines for administrative control, but was under the operational control of Seventh Air Force at Tan Son Nhut Air Base, Republic of Vietnam. The commander of the unit was a deputy commander of both Seventh and Thirteenth Air Forces.
The establishment of 7th/13th was a result of the complicated command arrangements made by the United States for the control of airpower during its involvement in Southeast Asia. Initial involvement was entirely in Thirteenth Air Force's area of responsibility, although it had little direct involvement with actual operations. When the expansion of forces in South Vietnam resulted in the establishment of 2d Air Division as the headquarter for those forces, the air division still reported to Thirteenth Air Force. The establishment of Seventh Air Force on a coequal level, however, made the establishment of a new operational headquarters a necessity.

Why this record matters
The phrase “military unit” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 7, 2025. The linked authority identifier is Q7457679. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1966 and 1973.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
