The Standard E-1 was an early AmericanArmyfighter aircraft, tested in 1917.[1] It was the only pursuit aircraft manufactured by the United States during World War I.[2] It arrived late in World War I, and as a result saw more use in the months following the Armistice than those preceding it.[3]
It proved unsuitable as a fighter, but 128 were bought as an advanced trainer.[5] Of these, 30 were powered by the Gnome rotary engine of 100 horsepower and 98 were powered by the LeRhone C-9 rotary engine of 80 horsepower.[3] After World War I, three were modified as RPVs.
A 1918 E-1 is on display at the Shannon Air Museum in Fredericksburg, Virginia. This airframe was found at a florist shop in Dayton, Ohio in the 1950s and restored for display.[2][7]
