Officially the UH-1 series is the Iroquois. But its unofficial name,
Huey, became so commonly used that the AH-1 attack version was
officially named the Huey Cobra. The Huey story traces back some
four decades. In 1955, with an interest in a utility helicopter
designed around a turboshaft engine, the Army had the Air Force
develop a new helicopter for its use. At that time the Army did
not have its own aircraft development capability.
The design selected, Bell's Model 204, was to be powered by a new
Lycoming T-53 engine of some 850 shaft horsepower and featured a
typical Bell two-blade teetering rotor. In the original helicopter
designation series, the first three aircraft received the XH-40
designation. First flight of the new design was in October 1956,
development and production following. When the Army adopted its own
two-letter designation system, the H-40 became the HU-1 (Helicopter
Utility). From this designation came Huey, the name by which it has
remained known. The DOD standard designation system reversed this to
UH-1, the first designation in the new DOD helicopter series. With
larger engines and increased capacity, the UH was developed through
successive models.
In 1962, after an evaluation of available types, the UH-1E version,
generally similar to the Army's UH-1B, was ordered for the Marine
Corps. These went into service in 1964 with VMO-1 being the first
squadron to receive them. Subsequently, 209 UH-1E aircraft were
delivered to the Marines by 1968. All, after the first 67, were
equipped with an improved rotor system.
Like their Army counterparts, the Marine Hueys served all manner of
combat roles, including that of armed gunships. For combat operations
in Southeast Asia, a Navy Light Attack Helicopter squadron was also
established using UH-1Bs acquired from the Army.
Other models followed for special Navy use: the HH-1Ks equipped for
air station search and rescue duty, the TH-1Ls as advanced instrument
trainers, and a few of the L models in standard utility configuration
as UH-1Ls. The Air Force had meanwhile ordered a "Twin Pac" engine,
improved utility version, the UH-1N, for general utility/transport
duties. In 1971 deliveries of this latest model to the Navy and
Marine Corps began. A total of 212 have been delivered, six in
VH-1N executive transport configuration. These UH-1Ns are widely
used in a transport, airborne battlefield command and control,
troop insertion/extraction, fire support coordination, medical
evacuation, search and rescue, armed escort/visual reconnaissance
or utility roles throughout the Navy and Marine Corps.
