Hiller UH12C

The UH12 civil helicopter is one of the earliest helicopters to enter service. First flown in 1948, the Hiller Company first marketed the aircraft for civil use. Despite its similarity to the U.S. military’s designation system UH12 is a company designation and not a military one. When the U.S. Army adopted the aircraft into service it was designated OH-23 and called the Raven. The C model was the first to have a completely enclosed cockpit. The UH12 has been in sporadic production since 1948. The Hiller Aircraft Company is currently producing the UH12E3 and a turbine powered version called the UH12E3T. Over 2,300 have been built since 1948.
