The Aircraft
Hughes Aircraft originally developed the OH-6 series of helicopters. With corporate takeovers and sales, the MD 500 series is built in Mesa Arizona by MD Helicopters. The OH-6J was built by Kawasaki Heavy Industries in Japan.
The original OH-6 was called the “Light Observation Helicopter”, which became “Loach”. The reason for the OH-6 was that in 1964 the US Army was ordered to turn all fixed wing aircraft over to the US Air Force. This meant the loss to the Army of the Cessna O-1 Bird Dog. The Loach was used as a replacement, utilized for forward observation, artillery spotting and air support with rocket pods, TOW or Hellfire, and gun pods available.
