This was done at the behest of the American commander in South Vietnam, General William C. Westmoreland, who saw the area of Laos that bordered the five northernmost provinces of South Vietnam as an extension of his area of operations.

Unlike Operation Barrel Roll and Steel Tiger, however, the bombing in the new area would be conducted by aircraft of the Republic of Vietnam Air Force and by U.S. Air Force units based in South Vietnam (aircraft participating in Barrel Roll and Steel Tiger were generally based in Thailand).

These missions were supplemented by 1,718 B-52 Stratofortress sorties under Operation Arc Light.

During the same time period, 132 U.S. aircraft or helicopters were shot down over Laos.
