Hiller Aircraft Company was founded in 1942 as Hiller Industries by Stanley Hiller to develop helicopters. Stanley Hiller, then seventeen, established the first helicopter factory on the West Coast of the United States, located in Berkeley, California, in 1942, under the name “Hiller Industries,” to develop his design for the coaxial-rotor XH-44 "Hiller-Copter" az amerikai hadsereg számára. Az XH–44 1944-ben állt hadrendbe. Henry J. Kaiser közreműködésével 1945-ben United Helicopters lett. A háború utáni években a United Helicopter számos innovatív helikoptertervet gyártott katonai és polgári célokra, beleértve a koaxiális rotort és a farok nélküli kialakításokat, valamint a hagyományosabb modelleket. 1949 januárjában egy Hiller 360 lett az első polgári helikopter, amely átszelte az Egyesült Államokat

A Hiller XH-44 was an experimental helicopter developed by Stanley Hiller Jr. in the early 1940s. It was the first successful coaxial helicopter in the United States and the first helicopter to use all-metal rotor blades. The XH-44 was designed as a proof-of-concept for Hiller’s innovative rotor system, which used counter-rotating blades to eliminate the need for a tail rotor.
The XH-44 had a two-seat open cockpit, a tubular steel frame, and a 90-horsepower Franklin engine. It made its first flight in July 1944 and demonstrated excellent stability and maneuverability. The XH-44 was later donated to the Smithsonian Institution and is currently on display at the Steven F. Udvar-Hazy Center in Virginia.
