The
UH-12 was Hiller Helicopters first production aircraft and
first flew in 1948. The design was very successful with both
two- and three-seat models that were sold to both civil and military
markets.
The U.S. Army acquired the UH-12 and designated it
the OH-23 Raven. The U.S. Navy designated this
helicopter the HTE.
More than 2,000 were built by the time production
ended in 1965. Production was re-launched in 1991.
