UH1

The UH-1 Iroquois, commonly known as Huey, is a family of utility helicopters produced by Bell Helicopter. Developed from the Bell Model 204 in the mid-1950s for the United States Army, the UH-1 was designed as a versatile, battlefield-proven transport and support aircraft. The designation UH stands for Utility Helicopter, and Iroquois was the Army's chosen name, later adopted by other operators.

The early UH-1s used a single turboshaft engine and a four-blade rotor; later variants added more power, twin engines, integrated avionics, and improved survivability. The Huey's large cabin can accommodate troops or cargo, and some variants feature a rear ramp for loading.

Operational history: The Huey became a symbol of the Vietnam era, serving extensively as troop transport, medical evacuation (medevac), cargo lift, and gunship in some configurations. It also served in search and rescue, disaster relief, and utility roles. Production continued through the 1960s and 1970s with multiple subvariants.

Variants: Notable models include UH-1A through UH-1N. The UH-1H was the most widespread variant during the Vietnam War era. In the 1990s and 2000s, Bell developed upgraded versions such as the UH-1Y Venom for the U.S. Marine Corps; the UH-1Y forms part of the H-1 upgrade program alongside the AH-1Z Viper. Civilian versions of the Huey include the Bell 212, derived from the UH-1 family.

Legacy: The Huey is one of the most recognizable helicopters in history and has influenced military helicopter design and operational doctrine, particularly in air mobility, medevac, and light utility roles.
