The Curtiss F6C Hawk was a late 1920s American naval biplane fighter aircraft. It was part of the long line of Curtiss Hawk airplanes built by the Curtiss Aeroplane and Motor Company for the American military.Originally designed for land-based use, the Model 34C was virtually identical to the P-1 Hawk in United States Army Air Corps service. The United States Navy ordered nine, but as the sixth example was built it was strengthened for carrier-borne operations and redesignated as the Model 34D.
