The Army ordered a number of the P-6E, but the plane, occupying the space between major wars, was never used in combat. Nevertheless, the Hawk led the way to the single wing planes that Curtiss would have ready when the U.S. entered the Second World War. Powered with a 600 hp engine, the P-6E had a top speed of 204 mph, a speed considered way too slow in the mid-1940’s. Armament was two .30 caliber machine guns.
The U.S. Air Force maintains an extensive collection of early and WW2 planes at its Dayton, Ohio museum… and a web site chock full of photos and information:http://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/
