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.
