"Light Helicopter, Heavy Hitter."
Blueprint of MH-3B shown
Conceptualization
In the late 1980s, during the Saril conflicts, the Arkinesian Federal Army found a clear gap in their helicopter transport and gunship roles. After the Iroquois Down incident in 1988, a result of the large UH-1 Iroquois crashing as a result of the tight space, it was determined that a new, small gunship/utility helicopter needed to be commissioned. The competing designs were based on the Amerikan Hughes 500 and Bell 206. The YH-3 was victorious, redesignated dependent on design the AH-3 or UH-3.
Design
MH-3A
The MH-3A is based on the Amerikan Hughes 500 series, in particular the OH-6 Cayuse. The MH-3A was the original development of the MH-3, the robust Hughes 500 frame chosen as it it could comfortably seat 4-6 passengers, as well as the two pilots. It also has two side doors, meaning it is capable of two side-defense weapons, either riflemen or mounted machine guns. Like most helicopters, the MH-3A uses the traditional two-rotor setup.
MH-3B
The MH-3B is a development from the Amerikan MD 520N. It uses MD's NOTAR (NO TAil Rotor) system, and uses compressed air torque instead of a second rotor, saving fuel. The MH-3B is quieter than the MH-3A, and includes some preliminary stealth design features. Like the MH-3A, it is equipped with FLIR as well as a variety of other modifications for various combat zones.
