Military vehicles sometime become a symbol of the era in which they are used. The most famous example is probably the Jeep that is the first image some people envision when they think about World War II. Another is the Bell UH-1 Iroquois helicopter, the “Huey” that hovers over many memories of the Vietnam War. The ubiquitous and distinctive sound it made in flight was described by one writer as “the sound of Vietnam.” The “whomp-whomp” sound of its main rotor must have been sweet music to the wounded soldier it was coming to evacuate for treatment.
Medical evacuation was the Huey’s original purpose, and it fulfilled that purpose well. A wounded soldier in Vietnam could expect to be evacuated for medical care within about one hour of being injured rather the 2.5 hours that a wounded U.S. soldier waited in the Korean Conflict. The speed with which medical care could be provided because of Hueys is reflected in mortality rates—less than 1 in 100 casualties in Vietnam, compared to 2.5 in 100 in Korea. Hueys are credited with evacuating about 2 million wounded soldiers throughout the Vietnam War.
The history of Hueys began when the U.S. Army asked for a new utility helicopter to use for medical evacuation for the Medical Service Corps in 1955. The Bell Helicopter Company entered its XH-40 design in the competition and received the contract. The first model made its initial test flight in 1956, and it went into production in 1959.
The Army changed the designation of the new helicopter from XH-1 to HU-1A (Army jargon for Helicopter, Utility, Model 1A), the designation that gave rise to the nickname “Huey,” even though the official designation changed to UH-1 in 1962. The official name, Iroquois, was rarely used, and many people do not recognize it as the name of the familiar Huey.
The Huey lived up to its designation as a “utility” machine because it was easily adaptable to many uses in addition to medical evacuations. The approximately 5,000 Hueys used in Vietnam served a variety of roles for the Army including gunship, troop transport, close air support, and other uses.
The original UH-1A carried up to six seats or two stretchers and were unarmed “slicks.” Their vulnerability led to development of the UH-1B, the Army’s first purpose-built gunship, which could be armed with M60 machine guns and rockets. Later models included M134 Gatling miniguns and two door gunners strapped into place for safety.
Pilots found that UH-1As and UH-1Bs did not have engines producing sufficient power to complete the tasks efficiently that were assigned to them. The original UH-1AU models were equipped with 700 shaft horsepower (shp) Lycoming T53-L-1A engines and were later upgraded to T53-L-5 engines that increased power to 770 shp. Power steadily increased. UH-1Bs received T53-L-5 engines tweaked to 960 shp and later models received T53-L-11 engines producing 1,100 shp.
Configurations also changed. The UH-1B was larger than the original model and could carry a crew of eight or three stretchers and a medical attendant. UH1-Cs were designed to accommodate all weapons in use at the time or under development. UH1-Ds could be armed with door guns and other weapons. They were also enlarged to carry twelve passengers or six stretchers. UH1-E models were modified for the United States Marine Corps, UH1-F was an Air Force model, UH1-H was a stretched UH1-B that could carry up to 15 passengers or six stretchers. The UH1-N Twin (powered by two Pratt and Whitney engines) was a model built for Canadian forces.
Pilots generally respected the Huey for its capabilities and reliability and liked flying it. Pilot Richard Jellison compared it to a dependable work truck: “It was easy to fix and could take any amount of punishment. Some of them came back with so many holes, you just wouldn’t believe they’d ever fly again.”
The Huey helicopter in the Vehicle Park at the Louisiana Maneuvers and Military Museum is included in the Living History Registry maintained by Don Barker. According to his information, it is serial number-0-13709, tail number 6413709, and was the 4,416th Huey built. It was constructed at the Bell Helicopter Corporation in Fort Worth, Texas. Originally a model UH1-D, it was later upgraded to model UH-1H. It was acquired by the U.S. Army in July1965 and was used in the Vietnam War and in Korea. According to records from the Vietnam Helicoptor Pilots Association, it was damaged by enemy fire at least six times in Vietnam. Its resilience allowed it to complete all mission objectives after five of the attacks and complete some of its mission objectives after the sixth attack. A former crew member who served on the helicopter visited the LMMM a few years ago and shared some of his memories about flying on it in Vietnam with staff member Martha Arrington.
The Museum’s Huey has a close neighbor. The Town of Ball Municipal Park has another Huey on display fewer than three miles away from the Museum. This one was the 10,132nd Huey built.
