Wright Field
Heart of the Army Air Corps

One of the greatest single factors that keeps US military planes leading the world parade is Wright Field at Dayton, Ohio. Here new designs are conceived, specifications drawn, orders issued and finally, finished airplanes and parts are tested. The Field is part of the Air Corps' Materiel Division — and materiel means every ounce of equipment from a rivet to a complete flying field. In the 750 acres are 50 hangars, shops laboratories, and a 500-acre flying field. Some 200 Air Corps officers supervise about 2,500 civilians. In the twelve months preceding last October, Air Corps contracts of approximately $200,000,000 were passed on at the Field, indicating a vast business enterprise as well as a scientific laboratory.

Every American plane, commercial and military, is more efficient due to research done at Wright Field. Improved types of engines, superchargers, high octane gasoline, night airways, airport lighting and many other now-common devices originated at Dayton, as well as propellers having less vibration, improved instruments, de-icers, radios and much other equipment.
