First Operation Farm Gate missions flown - Jan 13, 1962 - HISTORY.com

In the first Farm Gate combat missions, T-28 fighter-bombers are flown in support of a South Vietnamese outpost under Viet Cong attack.

By the end of the month, U.S. Air Force pilots had flown 229 Farm Gate sorties. Operation Farm Gate was initially designed to provide advisory support to assist the South Vietnamese Air Force in increasing its capability. The 4400th Combat Crew Training Squadron arrived at Bien Hoa Airfield in November 1961 and began training South Vietnamese Air Force personnel with older, propeller-driven aircraft. In December, President John F. Kennedy expanded Farm Gate to include limited combat missions by the U.S. Air Force pilots in support of South Vietnamese ground forces.

By late 1962, communist activity and combat intensity had increased so much that President Kennedy ordered a further expansion of Farm Gate. In early 1963, additional aircraft arrived and new detachments were established at Pleiku and Soc Trang. In early 1964, Farm Gate was upgraded again with the arrival of more modern aircraft. In October 1965, another squadron of A-1E aircraft was established at Bien Hoa. Secretary of Defense Robert McNamara approved the replacement of South Vietnamese markings on Farm Gate aircraft with regular U.S. Air Force markings. By this point in the war, the Farm Gate squadrons were flying 80 percent of all missions in support of the Army of the Republic of Vietnam (ARVN). With the build up of U.S. combat forces in South Vietnam and the increase in U.S. Air Force presence there, the role of the Farm Gate program gradually decreased in significance. The Farm Gate squadrons were moved to Thailand in 1967, and from there they launched missions against the North Vietnamese in Laos.
