The Verville-Packard R-1 Racer was a military racing aircraft that was based on Alfred Verville's previous VCP-1 design. The R-1 is sometimes known also as the VCP-R or the Verville-Packard 600. The R-1 was the first racing aircraft built for the United States Army Air Corps. The first R-1 was created from a VCP-1 in 1919, by installing the Packard V-12 engine.[1]
On November 27, 1920, Capt. Corliss Moseley, flying an R-1 racer, out of 24 track finishers, won the Pulitzer Trophy Race at Mitchel Air Force Base. The top speed was 156.54 mph.[2]

The Verville-Sperry R-3 Racer was a cantilever wing monoplane with a streamlined fuselage and the second aircraft with fully retractable landing gear, the first being the Dayton-Wright Racer.[3] The R-3 was designed by Alfred Verville. Its first production was in 1922. The R-3 was developed by the McCook Field Engineering Division and manufactured by the Lawrence Sperry Aircraft Company of Farmingdale, New York. Three aircraft were purchased. The airplanes used Lamblin radiators and a 300-horsepower Wright H-3 engine. The R-3s bore Air Service serial numbers 22-326 to 22-328.
At the 1922 Pulitzer Trophy race, all three R-3's started in the race, but only two finished. Lieutenant Eugene Barksdale finished fifth at around 181 mph. Lieutenant Fonda B. Johnson finished seventh, his engine freezing after landing. And Lieutenant St. Clair Streett broke an oil line and had a forced landing, damaging the airplane.[4]
For the 1923 Pulitzer, a Curtiss D-12 engine was installed in the plane which eliminated some vibration problems that the H-3 engine had. With the new engine the top speed now was approaching 233 mph. That year a Curtiss biplane was the winner. With Orville Wright officially observing from the ground, Lieutenant Alexander Pearson, Jr. set a World Speed Record of 167.74 mph over a 10-lap course on March 31, 1923 at Wilbur Wright Field.[5]
For the 1924 Pulitzer, the R-3, piloted by Lieutenant Harry H. Mills, won the race at a slow 215 mph. The ranked entry–a Curtiss biplane–crashed along the course.
After this race, the R-3 racers were sent to the McCook Field Museum.[6]
