Description With the introduction of Model 204, Bell wrote helicopter history once again. It all started in 1952 with a demand from the US Army for a multipurpose, medium-lift utility helicopter. The military designation was HU-1, but the machine was soon given the nickname, Huey. In response, the air force changed the official designation to UH-1 Iroquois, albeit to no effect; everyone in the helicopter field still knows which machine the term 'Huey' refers to.

The UH-1 is a very successful model, mainly because of its extremely effective overall design. It initially used a turbine engine, which provides a lot more power without the excessive weight of a piston-powered machine. Second, it placed the turbine engine on the roof of the fuselage, meaning that the machine had a very spacious cabin. These two design decisions gave the Huey its versatility; it could be used for many different missions such as transportation, for medivac purposes, or even in an attack role. The Huey was also the first Western turbine-powered military helicopter.

The UH-1 uses the well-known Bell two-blade rotorhead with a stabilizer bar, like that already in use on the Model 47. It is this two-bladed system that gives the Huey its characteristic 'wop-wop' sound.

The Vietnam War was the first battlefield in which the Huey saw service (1959). Due to the huge numbers used, this helicopter also became known to the wider public. There were many versions of the UH-1 Iroquois developed. The 204-based models can be recognized by their shorter fuselage length compared to the more familiar Model UH-1H (and newer versions), with its longer fuselage. Bell calls this machine the Model 205.

Both the UH-1 and the UH-1H also have civilian versions that are marketed by Bell as Model 204 and Model 205, which appeared in that order.
