Bell UH-1 Huey helicopter model NASA. The remarkable Bell UH-1 Iroquois (Huey) has been the quintessential all-purpose military helicopter for over three decades. It has been used by all four U.S. services, and international forces, in missions ranging from mountain rescue to troop transport, and from anti-armor to anti-submarine warfare. The Huey got its distinctive nickname from its original Army designation, the HU-1. It was later redesignated UH-1, under a tri-service agreement.
The last production aircraft was delivered in 1976. More than 9,000 were produced in 20 years. Considered to be the most widely used helicopter in the world, the Huey is flown today by about 40 countries. Evolving through 13 models, the Huey flew millions of flight hours in support of a wide variety of Army missions. It will always be remembered for its extensive service during the Vietnam War.
