A BRILLIANT GLASS-PANEL EXPERIMENTAL HUEY

dressed aerodynamic deficiencies of the armed UH-1B units
and further upped engine power. Following another stretch
of the cabin, the UH-1D emerged along with a multi-fuel
capable engine.
In the civilian market, these aircraft were designated Bell
204 and 205. Approximately 4,000 A through D models were
built, most being upgraded, armed or otherwise modified at
some point in their operational life. Some were later converted to the UH-1H standard, and most-produced version,
starting in 1966. The UH-1H's dual controls consist of a single
hydraulic system boosting the cyclic stick, collective lever, and
anti-torque pedals.
UH-1 war service
The UH-1 first saw service in combat operations during
the Vietnam War, with around 7,000 helicopters deployed.
Primary missions included general support, air assault, cargo transport, aeromedical evacuation, search and rescue,

electronic warfare, and ground attack. During the conflict,
the Huey was upgraded, notably to a larger version based
on the Model 205. This version was initially designated the
UH-1D and flew operationally from 1963.
Army UH-1
Designed as a troop carrier, the UH-1D replaced the
piston-powered Sikorsky CH-34 Choctaw, an anti-submarine
aircraft originally intended for the Navy, in service with the
U.S. Army. The UH-1D seated two pilots and additionally up
to 13 passengers or crew in its cabin.
UH-1s tasked with ground attack or armed escort were outfitted with rocket launchers, grenade launchers, and machine
guns. They were also modified locally by the military outfits
themselves, who fabricated their own mounting systems.
These gunship UH-1s were commonly referred to as "Frogs"
or "Hogs" if they carried rockets, and "Cobras" or simply
"Guns" if they had guns. UH-1s tasked and configured for
troop transport were often called "Slicks" due to their absence
of weapons pods. Slicks did have door gunners but were generally employed in the troop transport and medevac roles.
