ザ ベル UH-1 イロコイ (nicknamed “Huey”) is a utility military helicopter powered by a single turboshaft engine, with two-blade main and tail rotors. The first member of the prolific Huey family, it was developed by Bell Helicopter to meet a United States Army’s 1952 requirement for a medical evacuation and utility helicopter, and first flew in 1956. The UH-1 was the first turbine-powered helicopter to enter production in 1960 for the United States military, and more than 16,000 have been built since. The Iroquois was originally designated HU-1, hence the Huey nickname, which has remained in common use, despite the official redesignation to UH-1 in 1962. The UH-1 first saw service in combat operations during the Vietnam War, with around 7,000 helicopters deployed. The Bell 204 and 205 are Iroquois versions developed for the civil market.

The Evolution of the “Slick”
While the earlier UH-1B and UH-1C were the primary “Gunships,” the UH-1D was the definitive “Slick”—the troop transport that defined airmobile warfare. By lengthening the fuselage of the previous models, Bell created enough room to carry a full infantry squad of 12-14 troops. However, in the heat of Vietnam, “Slicks” were often up-armed with door guns to defend themselves during “Hot LZ” insertions, blurring the line between transport and combat support.

Anatomy of the Air Assault
- Extended Fuselage: The UH-1D is easily identified by its 41-inch fuselage stretch compared to the UH-1B/C. It features two large side windows on each sliding door instead of one, allowing for much larger internal volume.
- Turboshaft Power: The move from piston engines to the Lycoming T53 turboshaft was revolutionary. It allowed for a high power-to-weight ratio and gave the Huey its iconic “whump-whump” sound, caused by the tips of the two massive rotor blades breaking the sound barrier.
- Door Gunner Stations: For self-defense, UH-1Ds were equipped with M60D machine guns on flexible pintle mounts. These gunners provided suppressing fire while troops rappelled or jumped into landing zones.
- High-Visibility Greenhouse: The cockpit featured extensive glazing, giving pilots excellent visibility during low-level “nap-of-the-earth” flying to avoid enemy ground fire.
From “Slicks” to “Dustoff”
- The “Dustoff” Missions: The UH-1D became the ultimate ambulance. Dedicated Medevac Hueys saved thousands of lives, with a philosophy that any wounded soldier could be in a high-level hospital within an hour of being hit.
- Airmobile Doctrine: The UH-1D allowed the U.S. Army to move entire battalions across the jungle in minutes, bypassing difficult terrain and catching North Vietnamese forces by surprise.
- The “Gunship” Variant Confusion: While the “D” was a transport, it was often accompanied by the UH-1C “Frog” or “Hog”—short-bodied Hueys bristling with rocket pods and nose-mounted grenade launchers. Together, they formed the “Purple Gaggle” or “Firefly” hunter-killer teams.
- Global Legacy: More than 16,000 Hueys were built. The UH-1D/H model remains in service today with dozens of nations, a testament to its “overbuilt” and reliable design.
