Vietnam War: Operation Frequent Wind: The U.S. begins to evacuate U.S. citizens from Saigon before an expected North Vietnamese takeover. U.S. involvement in the war comes to an end.

As the final days of the Vietnam War drew to a tumultuous close, Operation Frequent Wind emerged as a desperate, yet meticulously planned, last-ditch effort to evacuate American citizens and at-risk Vietnamese from the besieged city of Saigon, South Vietnam. Carried out with remarkable urgency and precision on April 29th and 30th, 1975, this pivotal operation marked the climactic conclusion of America’s direct involvement in the conflict, preceding the inevitable takeover of the city by the North Vietnamese People’s Army of Vietnam (PAVN), an event famously known as the Fall of Saigon. More than 7,000 individuals found safe passage via helicopter from various points across the sprawling metropolis, creating indelible images that would forever symbolize the chaotic and heartbreaking end of an era.

The seeds of this dramatic evacuation were sown much earlier, with standard contingency plans for American embassies always at the ready. However, as the military situation in South Vietnam deteriorated rapidly, a palpable sense of urgency began to grip Saigon. By early March 1975, fixed-wing aircraft had already begun the crucial task of airlifting civilians from Tan Son Nhat Airport to neighboring countries. As mid-April approached, it became clear that a full-scale helicopter evacuation might be necessary, and preparations were swiftly put in motion. Understanding the gravity of the impending collapse, the U.S. Navy assembled Task Force 76 off the coast near Vũng Tàu. This formidable naval force stood ready not only to support a massive helicopter airlift but also to provide air support if the situation on the ground escalated into direct conflict. Fortunately, air support proved unnecessary; the North Vietnamese, in a calculated strategic move, paused their advance for approximately a week at the outskirts of Saigon. This pause allowed the South Vietnamese government to crumble from within, and crucially, it provided a window for the relatively unopposed evacuation of Americans, potentially averting a direct, costly confrontation with the United States military.

The Final Hours: From Fixed-Wing to Helicopter

The turning point arrived abruptly on April 28th. Tan Son Nhat Air Base, adjacent to the civilian airport, was rocked by a devastating artillery barrage and came under attack from Vietnamese People's Air Force aircraft, signaling the definitive end of the fixed-wing evacuation window. This onslaught triggered the immediate commencement of Operation Frequent Wind. Up until that point, the fixed-wing airlifts had successfully moved an impressive 50,493 individuals, including a significant number of 2,678 Vietnamese orphans, a poignant detail that underscored the humanitarian dimension of the crisis.

Operation Frequent Wind itself kicked off around 14:00 on the afternoon of April 29th. The primary evacuation hub became the Defense Attaché Office (DAO) compound, a sprawling complex that housed American military personnel. From here, a continuous stream of helicopters lifted off, carrying evacuees to the waiting naval fleet offshore. The evacuation proceeded with remarkable efficiency, concluding that night with only limited small arms fire causing minor damage to the incoming and outgoing helicopters. The U.S. Embassy in Saigon, initially designated as a secondary pickup point primarily for embassy staff, quickly became overwhelmed. Thousands of desperate South Vietnamese, many of whom had worked alongside Americans or feared retribution under the new regime, surged towards its gates, scaling walls and clamoring for a spot on a helicopter. The scenes of desperation at the embassy, particularly the iconic image of people climbing a ladder to a helicopter on the rooftop, became a powerful and enduring symbol of the war's conclusion. The embassy evacuation, fraught with peril and heartbreaking choices, was finally completed at 07:53 on April 30th, just hours before Saigon fell. Despite the herculean efforts, some Americans made the difficult choice to stay, others were inadvertently left behind, and approximately 400 third-country nationals remained stranded at the embassy, a testament to the chaotic and hurried nature of the departure.

A Sea of Humanity: Self-Evacuation and Naval Response

Beyond the official channels, tens of thousands of Vietnamese citizens, sensing the impending collapse, undertook their own daring self-evacuations by sea and air. As the Republic of Vietnam crumbled, an extraordinary armada of boats, ships, and even Republic of Vietnam Air Force (RVNAF) helicopters and fixed-wing aircraft streamed out towards the sanctuary of the U.S. evacuation fleet positioned in the South China Sea. The decks of the U.S. Navy ships quickly became overwhelmed with arriving helicopters. In a stark demonstration of prioritizing lives over matériel, many helicopters, after safely depositing their passengers, were unceremoniously pushed overboard to clear space for more arrivals. Pilots of other incoming helicopters were given the harrowing instruction to drop off their precious cargo and then ditch their aircraft in the sea, where rescue teams waited to retrieve them. In total, Operation Frequent Wind directly evacuated 1,373 Americans and 5,595 Vietnamese and third-country nationals by helicopter. However, the larger humanitarian scope of this period is reflected in the staggering number of 138,869 Vietnamese individuals who, whether through Frequent Wind or self-evacuation, ultimately found themselves under the care of the United States for processing as refugees, embarking on new lives far from their war-torn homeland.

A notable, albeit less dramatic, detail of Operation Frequent Wind was its role as the combat debut of the advanced F-14 Tomcat aircraft. These formidable fighter jets, providing air cover high above the frantic evacuation, stood ready to deter any potential aerial threats, ensuring the safety of the vulnerable transport helicopters below, even though they were ultimately not engaged in direct combat.
