Operation Rolling Thunder marked the first sustained American assault on North Vietnamese territory and thus represented a major expansion of U.S. involvement in the Vietnam War. In an effort to convince the North Vietnamese government to abandon its support of the insurgency in South Vietnam, President Johnson began a new bombing campaign in March 1965, known as Operation Rolling Thunder. Lasting from 2 March 1965 until 1 November 1968, Rolling Thunder was the longest bombing campaign in United States history. The massive Rolling Thunder offensive is recalled in interviews with the F-105 Thunderchief pilots, as well as Navy Yankee Station A-4 Skyhawk pilots.
