UH-1 Huey series.
Designation: Bell 205 / UH-1D/H Iroquois (Huey)
Classification Type: Assault, Support and Transport Helicopter
Contractor: Bell Helicopter Company - USA
Country of Origin: United States
Initial Year of Service: 1963
Based on the successful UH-1B Huey model, the UH-1D was an improved and more
powerful version that included increased cabin space for up to 14
passengers. As the YUH-1D (taken from the base Bell 205 airframe), the
system first appeared in 1960 and was placed into production by 1963.
With over twice the seating capacity of the B and C Hueys, the D model was
fitted with an appropriately-powered T53-L-11 turboshaft engine driving the
two-blade main rotor and tail rotor sections. The further design - the UH-1H
- provided an even more powerful T53-L-13 turboshaft engine, which the US
Army saw delivered in 1967.
The D and H models were the two production variants which saw extensive use
throughout the Vietnam conflict as MedEvac, close-support, transport or
assault. The Vietnam gunship variants could be fitted with a myriad of
armaments including high-explosive rockets, machine guns, miniguns and
grenade launchers. Door-mounted pintle positions and wing stubs were
provided to compliment this impressive armament array. In short, the Huey
airframe proved to be quite valuable to the air-only accessible areas of the
jungle - necessitating the need for helicopter development to continue in
the any modern military.
