The mission of the Seventh/Thirteenth Air Force was originally to conduct bombing operations in the Democratic Republic of Vietnam (Operation Rolling Thunder); to carry out interdiction missions against the People's Army of Vietnam's logistical network in southeastern Laos known as the Ho Chi Minh Trail (Operation Steel Tiger); and to support the clandestine war in northern Laos (Operation Barrel Roll). After 1 November 1968, Rolling Thunder came to an end and the unit was dedicated to its Laotian operations. The Seventh/Thirteenth also participated in the massive Operation Commando Hunt, which was, in turn, supported by the sensors and computers of Operation Igloo White, based at Nakhon Phanom, Thailand.
