The most widely used military helicopter, the Bell UH-1 series Iroquois,
better known as the "Huey", began arriving in Vietnam
in 1963. Before the end of the conflict, more than 5,000 of these versatile
aircraft were introduced into Southeast Asia. "Hueys"
were used for MedEvac, command and control, and air assault; to transport
personnel and materiel; and as gun ships.
Considered to be the most widely used helicopter in the world, with
more than 9,000 produced from the 1950s to the present,
the Huey is flown today by about 40 countries.
Bell (model 205) UH-1D (1963) had a longer fuselage than previous models,
increased rotor diameter, increased range, and a
more powerful Lycoming T53-L-11 1100 shp engine, with growth potential
to the Lycoming T53-L-13 1400 shp engine. A
distinguishing characteristic is the larger cargo doors, with twin
cabin windows, on each side. The UH-1D, redesigned to carry
up to 12 troops, with a crew of two, reached Vietnam in 1963. The UH-1D
has a range of 293 miles (467km) and a speed of
127 mph (110 knots). UH-1Ds were build under license in Germany. UH-1D
"Hueys" could be armed with M60D door guns,
quad M60Cs on the M6 aircraft armament subsystem, 20mm cannon, 2.75
inch rocket launchers, 40mm grenade launcher in
M5 helicopter chin-turret, and up to six NATO Standard AGM-22B (formerly
SS-11B) wire-guided anti-tank missiles on the
M11 or M22 guided missile launcher. The UH-1D could also be armed with
M60D 7.62mm or M213 .50 Cal. pintle-mounted
door guns on the M59 armament subsystem.
The MedEvac version UH-1V could carry six stretchers and one medical attendant.
Bell (model 205A-1) UH-1H (1967-1986) was identical to the UH-1D but
was equipped with an upgraded engine that
allowed transport of up to 13 troops. The UH-1H has a two-bladed semi-rigid
seesaw bonded all metal main rotor and a
two-bladed rigid delta hinge bonded all metal tail rotor. The UH-1H
is powered by a single Lycoming T53-L-13B 1400 shp
turboshaft engine. More UH-1H "Hueys" were built than any other model.
The UH-1H was licensed for co-production in the
Republic of China (Taiwan) and in Turkey. UH-1H "Nighthawk" was equipped
with a landing light and a pintle mounted M134
7.62mm "minigun" for use during night interdiction missions. The AH-1G
Cobra was often flown on night "Firefly" missions
using the UH-1H "Nighthawk" to locate and illuminate targets.
The UH-1N is a twin-piloted, twin-engine helicopter used in command
and control, resupply, casualty evacuation, liaison and
troop transport. The Huey provides utility combat helicopter support
to the landing force commander during ship-to-shore
movement and in subsequent operations ashore.he aircraft can be outfitted
to support operations such as command and control
with a specialized communication package (ASC-26), supporting arms
coordination, assault support, medical evacuation for up
to six litter patients and one medical attendant, external cargo, search
and rescue using a rescue hoist, reconnaissance and
reconnaissance support, and special operations using a new navigational
thermal imaging system mission kit.
The goal of the USMC H-1 Upgrades Program is to achieve a platform that
meets the growing needs of the Marine Corps.
The 4BW and 4BN will be an upgraded version of the current AH-1W and
UH-1N Helicopters. The 4BW and 4BN will
share a common engine, Auxiliary Power Unit, four-bladed main and tail
rotor system, transmission, drive train, and tail boom.
The purpose of these modifications is to achieve commonality in both
aircraft, thereby reducing logistical support, maintenance
workload, and training requirements. The replacement of the two bladed
rotor system with a common four bladed rotor system
will achieve improved performance, reliability, and maintainability.
The addition of an infrared suppresser to the aircraft will
improve survivability. The 4BW will also include a newly developed
cockpit, which will result in nearly identical front and rear
cockpits that simplify operator and maintainer training and maintenance.
