In 1925, the Curtiss Aeroplane and Motor Company built a fast racer that it quickly sold to both the U.S. Army and Navy. The landplane was designated the R3C-1. Piloted by Lt. Cyrus Bettis, it won the Pulitzer Trophy Race on October 12, 1925, at a speed of 248.9 mph. It was then fitted with streamlined single-step wooden floats and redesignated the R3C-2. On October 25, it won the Schneider Cup Race, piloted by Army Lt. James H. Jimmy Doolittle. The next day, Doolittle flew the R3C-2 over a straight course at a world record speed of 245.7 mph-aviation-central.com
