UH-1As armed with two .30 cal. machine guns and two eight-tube 2.75 inch rocket launchers were first used in late 1963. The UH-1A was armed with various combinations of 7.62mm machine guns, 20mm cannon, and a chin-turret mounted 40mm grenade launcher. Some early Huey gun ships were armed with quad M60C 7.62mm machine guns mounted on the M6 aircraft armament subsystem.

UH-1B/UH-1C Hueys were used with moderate success as a gun ship with door mounting M60D 7.62 machine guns on the M23 armament subsystem. They could also be armed with a pod or side-mounting six-barrel minigun and seven-tube XM157 or M158 2.75 inch (70mm) rocket launcher on the Emerson Electric M21 armament subsystem, and the M5 chin-turret mount for a 40mm grenade launcher. The UH-1B was also armed with two fixed-mounting M24A1 20mm cannon on the XM31 armament subsystem. The M60A1 reflex sight was used for sighting guns and rockets on the UH-1B, UH-1C, and UH-1M Huey. With the fielding of the larger UH-1D as the Army's primary utility helicopter, the smaller UH-1Bs/UH-1Cs assumed the gunship role as their primary mission.

Bell (model 205) UH-1D (1962) had a longer fuselage than previous models, increased rotor diameter, increased range, and more powerful Lycoming T53-L-9A or T53-L-11D 1100 shp engines, with growth potential to the Allied Signal Engines (ASE) T53-L-13B 1400 shp engine. The "towel rack" FM antenna and pitot were located on top of the cabin on the UH-1D. The UH-1D also featured a larger double windowed sliding door, and small single window hinged door, just behind the pilot's door. The UH-1D, redesigned to carry up to 13 troops, with a crew of two, reached Vietnam in 1963. The MedEvac version UH-1V could carry six stretchers and one medical attendant. The UH-1D has a range of 293 miles (467km) and a speed of 127 mph (110 knots). UH-1Ds were built under license in Germany. The primary armament subsystem used with the UH-1D/UH-1H Huey is two door mounting M60D 7.62mm machine guns on the M23 armament subsystem.
