HISTORY

  • The H-23D Raven was used as an observation, utility, and MedEvac helicopter during the Korean War, but also used for observation in the early years of the Vietnam War. Built on the earlier model 360 (UH-12), it was a three-place aircraft built by Hiller (formerly United Helicopters). Its flight debut in 1948 led to its adoption by the U.S. and French militaries as well as commercial enterprises.
  • The H-23 “D” model was developed solely for military use. It was distinguished from other earlier models by a more dependable transmission and a Lycoming O-435-23C engine. Its rotor was two-blades as was its metal tail rotor.
  • The H-23D was able to carry armament in the form of .30-caliber or 7.62 mm machine guns with sighting systems. A total of 348 H-23Ds were built for the U.S. Army.
