The Bell UH-1 Iroquois (unofficially Huey) is a military helicopter powered by a single turbo shaft engine, with a two-bladed main rotor and tail rotor. The helicopter was developed by Bell Helicopter to meet the United States Army's requirement for a medical evacuation and utility helicopter in 1952, and first flew on 20 October 1956. Ordered into production in March 1960, the UH-1 was the first turbine-powered helicopter to enter production for the United States military, and more than 16,000 have been produced worldwide.

The first combat operation of the UH-1 was in the service of the U.S. Army during the Vietnam War. The original designation of HU-1 led to the helicopter's nickname of Huey. In September 1962, the designation was changed to UH-1, but "Huey" remained in common use. Approximately 7,000 UH-1 aircraft saw service in Vietnam.

The 352 licensed German UH-1D variants built by Dornier between 1967 and 1981 saw service with the military (Bundeswehr) by the German Army and German Air Force as light utility as well as search and rescue (SAR) helicopters. In addition the German Federal Police (Bundespolizei) made extensive use of the UH-1 before replacing them with newer Eurocopter EC135 helicopters
