America's need for combat aircraft led to the design and development of the Standard E-1 by the Standard Aircraft Corporation of Elizabeth, New Jersey in 1917. The last American aircraft produced before the end of the war, the Standard E-1 entered service in early 1918 but never saw combat. Although it was stable and maneuverability, it proved too slow and underpowered for use as a fighter. Instead, the United States Air Service accepted it for use as an advanced trainer.
