Operation Shufly was a United States Marine Corps operation to improve the mobility of Army of the Republic of Vietnam (ARVN) forces in the early phases of the Vietnam War from 1962 to 1965. Beginning on 15 April 1962, Marine helicopter squadrons, associated maintenance units and air traffic control detachments deployed to Sóc Trăng Airfield in the Mekong Delta and later to Da Nang Air Base rotating every four months in order to provide assault support and CASEVAC assistance during combat operations. By early 1965 half of the Marine Corps' medium helicopter squadrons had rotated through a "Shufly" deployment. The operation ended on 8 March 1965, when the 9th Marine Expeditionary Brigade came ashore in Vietnam as the vanguard of the United States' commitment of large numbers of regular combat units into South Vietnam.

Da Nang Air Base (1930s–1975) was a French Air Force and later Republic of Vietnam Air Force (RVNAF) facility located in the city of Da Nang, Vietnam. During the Vietnam War (1959–1975), it was a major base with United States Army, United States Air Force (USAF), and United States Marine Corps (USMC) units stationed there. Air Vietnam also used the facility from 1951 to 1975 for civilian domestic and international flights within Southeast Asia.
