About the Hiller Aircraft Corporation UH-12

The Hiller UH-12 is a pioneering American light utility helicopter that helped establish rotorcraft as practical workhorses in the postwar era. First flown in 1948, the UH-12 was developed by Stanley Hiller Jr.'s company and became one of the first commercially successful helicopters in the United States, serving ranchers, pipeline inspectors, forestry operations, and flight schools for decades. Its military sibling, the H-23 Raven, saw extensive service with the U.S.

Army during the Korean War for observation and medevac missions, earning a reputation for ruggedness and reliability in austere conditions. The civilian UH-12 variants—including the popular UH-12E with its distinctive three-seat cabin and bubble canopy—became a common sight across rural America through the 1950s and 1960s. Powered by a single piston engine (typically a Franklin or Lycoming producing around 305 horsepower in later models), the UH-12 could carry two to three occupants and cruise at roughly 80 knots with a never-exceed speed of 95 knots.

Its two-blade rotor system and relatively simple mechanical design made it accessible to owner-operators, though it lacked the performance envelope of turbine-powered successors. Production continued into the 1970s with over 2,000 units built across all variants, and a small number remain airworthy today in private hands, often maintained by enthusiasts who appreciate its place in rotorcraft history. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
