The Hiller OH-23 Raven is a two, three, or four-place, military light observation helicopter based on the Hiller Model 360. The Model 360 was designated by the company as the UH-12 ("UH" for United Helicopters),[1] which was first flown in 1948. Initially it was a two-place helicopter powered by a piston engine that entered service in the late 1940s, it went on to be a popular military and civilian light helicopter in the late 20th century.

A Hiller UH-12 was the first helicopter to make a transcontinental flight across the USA, in 1949. It served in the Korean War with U.N. forces and also in Vietnam. It was an important early helicopter and was widely used internationally, in U.K. service it was called the Hiller HT Mk 1 and Mk 2, and the U.S. Navy also used it as the HTE-1 for training. It was sold commercially as the UH-12 (This was a company designation not military), though some military operators used the company designation. Some later models were designed for turbine power, and a version with 4-seats was also sold. In Canada, UH-13E served the military as the CH-112 Nomad.

Hiller was taken over by Fairchild in 1964. A new company, Hiller Aviation, took over support of some UH-12 variants in the 1970s, and later became Rogerson Hiller.[2]
