The Hawk GafHawk ("General Aviation Freighter") was a small, turboprop-powered freighter aircraft developed in the United States in the 1980s but which only flew in prototype form. It was designed by Hawk International as a means of transporting drilling equipment in and out of remote locations, and was designed to be simple, rugged, and have good STOL and rough-field performance. The resulting design was a boxy aircraft with a rectangular-section fuselage with a high-set tail and rear loading ramp. The high aspect-ratio wings were high-set and braced with struts. The landing gear was fixed and of tricycle configuration, with the main units having dual wheels.
Certification proved elusive, however, and Hawk eventually abandoned the project without building any other examples.
