The Bell UH-1 is perhaps the best-known American helicopter in the world. Made famous by its use in Vietnam, versions of the “Huey” remain in both military and civil service today. Designated HU-1 by the Army and H-40 by the Air Force the first Hueys flew in 1958. In 1962, the designations were changed to UH-1. By the mid-1960s Hueys could be found in every branch of the U.S. military and were entering the civil and foreign military markets.
The UH-1N was developed originally for the Canadian military and first flew in 1969. The were generally called “Twin Huey” because they were upgraded to have two engines instead of the original model’s single engine. They were also larger with a longer cabin and greater carrying capacity. The UH-1N served extensively with the U.S. military with the last ones being retired in 2020 by the Marine Corps. Advanced versions of the Twin Huey remain in U.S. military service and in commercial, civil government, and military service around the world.
