The Hiller OH-23 Raven was an American light observation helicopter manufactured by the Hiller Aircraft Corporation.
History[]
The OH-23 was based on the Hiller Model 360, which was designed by Stanley Hiller in 1947. The design was selected for use by the US Army after it completed a transcontinental flight of the United States in 1949 and was designated H-23. It saw service during the Korean War in the observation, utility, and medevac roles. It was even used early in the Vietnam War, before being replaced by the OH-6 Cayuse. The Raven also served with a number of other countries, including France, South Korea, and Great Britain.
