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.
