Operation Frequent Wind
In April 1975, Enterprise, Midway, Coral Sea, Hancock, and Okinawa were deployed to waters off Vietnam for evacuation contingencies as North Vietnam, in violation of the Paris Peace Accords, launched a conventional invasion of South Vietnam. On 29 April, Operation Frequent Wind was carried out by US Navy and Marine Corps helicopters from the 7th Fleet. The Operation involved the evacuation of American citizens from Saigon.
President Ford ordered helicopter evacuation when PAVN shelling forced the cessation of fixed-wing evacuation from Tan Son Nhut airport. With fighter cover the helicopters landed at the US Embassy, Saigon and the DAO Compound to pick up evacuees. The last helicopter lifted off the roof of the US Embassy, Saigon at 07:53 on 30 April 1975 carrying the last 11 Marine Security Guards. During Operation Frequent Wind, aircraft from Enterprise flew 95 sorties.
That was just before my time but many of my shipmates were in Operation Frequent Wind (USS Midway.)
