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 was the landplane version and Cyrus Bettis won the Pulitzer Trophy Race in one on 12 October 1925 with a speed of 248.9 mph (400.6 km/h).
The R3C-2 was a twin float seaplane built for the Schneider Trophy race.
In 1925, it took place at Chesapeake Bay in Baltimore, Maryland.
With 232.57 mph (374.29 km/h), 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 245.7 mph (395.4 km/h), 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 231.364 mph (372.344 km/h).
