The Vietnam War’s icon was arguably the UH-1 helicopter. Officially designated the Iroquois (‘Huey’ is more of a term of endearment), this helicopter has been the most-produced in history, first flying in 1956 — that means it has just over six decades of service with the United States military!
Over 7,000 Hueys were used in Vietnam, and 2,500 were lost during the war.
According to the Naval Institute Guide to World Military Aviation, the UH-1D had the ability to carry up to 16 passengers and crew.
The chopper could also carry just under 3,900 pounds of equipment in the cabin or 5,000 pounds in an external sling. It also could serve as a potent gunship, firing 70mm rockets, M60 machine guns in 7.62mm NATO, and M134 miniguns.
The secret to the Huey’s success was a gas turbine engine that not only was able to perform at higher temperatures and in less-dense air than previous helicopters, but it was also much lighter than previous helicopter engines.
This allowed the Huey to be smaller (48-foot rotor diameter, 57 foot length) and lighter — making it fast (a top speed of 135 miles per hour) and maneuverable. It had a range of 315 miles, giving American troops the ability to strike hard and fast at a distance.
The chopper’s mobility meant that in a one-year tour, the average infantry soldier saw 240 days of combat. For some perspective, in the Pacific Theater during WWII, the average grunt saw 40 days over the nearly four years that conflict lasted.
Today, versions of the UH-1 are still in service with the Marine Corps (the UH-1Y Venom), the Air Force (UH-1N), and Navy (UH-1N). The Army’s last Huey mission was flown on Dec. 15, 2016. According to an Army release, the helicopter was handed off to the Louisiana State Police a week later.
