The Curtiss R3C is an American racing aircraft built in landplane and floatplane form. It was a single-seat biplane built by the Curtiss Aeroplane and Motor Company.
The R3C-1[1] was the landplane version and Cyrus Bettis won the Pulitzer Trophy Race in one on 12 October 1925 with a speed of 248.9mph.
The R3C-2 was a twin float seaplane built for the Schneider Trophy race. In 1925, from 23 to 26 October, it took place at Chesapeake Bay in Baltimore, Maryland. With 232.57mph, pilot Jimmy Doolittle won the trophy with a Curtiss R3C-2. The other two R3C-2s, piloted by George Cuddihy and Ralph Oftsie, did not reach the finish line. The next day, with the same plane on a straight course, Doolittle reached 245.7mph, a new world record. For the next Schneider Trophy, which took place on 13 November 1926, the R3C-2's engine was further improved, and pilot Christian Franck Schilt took second place with 231.364mph.
The R3C-2 that Jimmy Doolitle piloted to victory in the 1925 Schneider Trophy race is preserved at the National Air and Space Museum's Steven F. Udvar-Hazy Centre, at Washington Dulles Airport, Virginia. It still wears its '3' 1925 racing number.
