Bell UH-1 Iroquois Helicopter (Huey)
The Bell UH-1 Huey has been the most important military utility helicopter from its introduction in the 1950s into the 21st century. The Hueys were used for MedEvac, command and control, air assault, transport of personnel, supplies and equipment, and as gun ships. More than 16,000 UH-1s (in a sequence of models) were produced through 1976. Hueys continue in use by the U.S. military and in over 45 countries.

Bell UH-1 Iroquois (Huey) Helicopter
The UH-1 Iroquois (Huey) Helicopter was first delivered to the Army in 1959, as the UH-1A, the first military turbine engine helicopter. In Vietnam, where the first Hueys arrived in 1962, it was the primary MedEvac helicopter as well as the primary air assault helicopter platform, making the air-mobility concept a reality. By the end of the Vietnam conflict in 1975, more than 5,000 UH-1 Iroquois helicopters had been introduced into Southeast Asia. 2,500 Hueys were lost in Vietnam, about equally due to combat and operational accidents.
One of the basic design specifications for the UH-1 was the requirement by the Aviation Section of the Surgeon General's Office for the Army's utility helicopter to carry at least four litter cases; hence the Huey had a maximum width of 98 1/2 inches to accommodate stretchers sideways.
The name Huey came from its original U.S. Army designation as the HU-1, changed to Utility Helicopter UH-1 in 1962 when it became a tri-service procurement. The UH-1 Huey was utilized by all the U.S. service branches for decades. It was partially replaced in the U.S. Army by the UH-60 Blackhawk, but continues in Army service as a utility craft. In the mid-2000s, the USMC still employs the UH-1N and UH-1Y models.
Characteristics of the UH-1A Iroquois are:
|Rotor diameter||43' 9"||44'||44'||48' 3"|

Other Models of the UH-1 Iroquois (Huey)
There are other models of the UH-1 Iroquois, introduced to extend the service life and fill special requirements.
- The UH-1H replaced the UH-1D in 1967, with a more powerful L-13 engine -- more UH-1Hs were built than any other model
- UH-1N (See photo caption below)
- UH-1H units were modified with litter racks and avionics upgrades to create the MedEvac UH-1V (1980s) -- capacity was six stretchers and one medical attendant
- A small number of UH-1C units were fitted with the Lycoming T53-L-13B 1400 shp engine -- with this modification they were designated UH-1M
- A few model UH-1F Hueys were modified for a classified psychological warfare role, changing model to UH-1P (1969)
- UH-1Y "Venom" is an upgraded UH-1N utilized by the USMC, with greater payload, speed, range and survivability than the UH-1N

USAF UH-1N Huey. The N model is almost the same as the civilian Bell 212 with small differences in the electrical system. The N and the 212 are both powered with two Pratt & Whitney PT-6 engines called a "TwinPac". Each of these engines have between 900 and 1000 hp. UH-1N was the primary Huey used by 1st Special Operations Wing.
