Operation Frequent Wind
Operation Frequent Wind was the final phase in the evacuation of American civilians and "at-risk" Vietnamese from Saigon, South Vietnam, before the takeover of the city by the North Vietnamese People's Army of Vietnam (PAVN) in the Fall of Saigon. It was carried out on 29–30 April 1975, during the last days of the Vietnam War. More than 7,000 people were evacuated by helicopter from various points in Saigon. The airlift resulted in a number of enduring images.
Evacuation plans already existed as a standard procedure for American embassies. At the beginning of March, fixed-wing aircraft began evacuating civilians from Tan Son Nhat Airport through neighboring countries. By mid-April, contingency plans were in place and preparations were underway for a possible helicopter evacuation. As the imminent collapse of Saigon became evident, the U.S. Navy assembled Task Force 76 off the coast near Vũng Tàu to support a helicopter evacuation and provide air support if required. In the event, air support was not needed as the North Vietnamese paused for a week at the outskirts of Saigon, possibly waiting for the South Vietnamese government to collapse and avoiding a possible confrontation with the U.S. by allowing the mostly-unopposed evacuation of Americans from Saigon.[1][2]:14
On 28 April, Tan Son Nhut Air Base (next to the airport) came under artillery fire and attack from Vietnamese People's Air Force aircraft. The fixed-wing evacuation was terminated and Operation Frequent Wind began. During the fixed-wing evacuation 50,493 people (including 2,678 Vietnamese orphans) were evacuated from Tan Son Nhut.[3] The evacuation took place primarily from the Defense Attaché Office compound, beginning around 14:00 on the afternoon of 29 April, and ending that night with only limited small arms damage to the helicopters. The U.S. Embassy in Saigon was intended to only be a secondary evacuation point for embassy staff, but it was soon overwhelmed with evacuees and desperate South Vietnamese. The evacuation of the embassy was completed at 07:53 on 30 April, but some Americans chose to stay or were left behind and some 400 third-country nationals were left at the embassy.
