The Dayton-Wright XO-3 was an aircraft project developed by Dayton-Wright in 1924.{{cite book|first=John|last=Wegg|title=General Dynamics Aircraft and Their Predecessors |year=1990|publisher=Putnam|place=London|page=41|isbn=9780851778334}}

Design and development

A contemporary of the successful Douglas O-2, it was an orthodox two seat biplane, powered by a {{convert|645|hp|kW|0}} Wright T-3 V12 engine. The prototype, numbered 23-1254, built by Wright Aeronautical after the demise of Dayton-wright, was allocated the Wright field number P-376.{{cite book|first=John|last=Andrade|title=U.S. Military Aircraft Designations and Serials Since 1909|year=1979|place=Earl Shilton|publisher=Midland Counties Publications|isbn=9780904597219|page=137}}{{cite web|last1=Eckland|first1=K.O.|title=Dayton-Wright|url=http://aerofiles.com/_dayton.html|website=aerofiles.com|accessdate=20 March 2018}}{{cite web|last1=Eckland|first1=K.O|title=Dayton-Wright XO-3: photograph|url=http://aerofiles.com/dayton-xo3.jpg|website=Aerofiles|accessdate=20 March 2018}}{{cite web|title=Wright Field regs #4|url=http://aerofiles.com/wright-field.html|website=aerofiles.com|accessdate=20 March 2018}}

Operational history

After trials at Wright Field the XO-3 was rejected and returned to Wright Aeronautical, where it saw service as an engine test-bed, primarily for the Wright R-1750 Cyclone, with the civil registration X-1087. Officially it was named Mohawk by Wright, but unofficially it received the sobriquet Iron Horse.
