The development of the multipurpose aircraft of the Hiller Ten99 model began to be carried out by American design engineers in the second half of the 50s of the last century. The aircraft manufacturers were faced with the important task of creating a multipurpose aircraft capable of finding wide application, both in civil and military aviation, in particular, the helicopter was supposed to be used to transport people, transport goods, and also as a patrol vehicle and an independent combat unit. ...

The helicopter was first developed under the requirements of the US Navy, however, since in the course of testing the aircraft was unable to meet all the requirements of the American military command, and for its commercial use because of the high cost he also did not fit, so the project and did not mass-produced.

In 1961, the Hiller Ten99 helicopter made its first test flight, and despite the fact that aircraft manufacturers had intentions to optimize the design of the aircraft, the project was still very expensive and could not fully justify the costs, and therefore, already at the beginning of 1962 of the year was officially named closed.

The cabin Hiller Ten99 aircraft can accommodate up to 6 people, including one pilot and five troops, when it came to his military assignment. Among other things, the helicopter can also carry out transportation on its board of goods total weight of up to 726 kg, or else used as a combat aircraft, for which it was intended to equip a machine gun and two sets of unguided missiles to combat armored targets.
