List of New York Contractors for Aircraft Supplies

This document lists in detail the aircraft components that were produced by each contractor.  All of these contractors were located in New York.  When the United States entered the war, its air power was weak.  Then, in July 1917, Congress appropriated a hefty $675 million to build an air force.  During peak production late in 1918, the U.S. aircraft industry employed more than 200,000 people.
The aircraft changed the modern battlefield.  The early airplanes were used by both sides only for scouting. The period between 1914 and 1918 saw not only tremendous production, but also tremendous development in aircraft technology.  Early dogfights, or individual air combats, resembled duels.  At first pilots sat in their open cockpits and shot at each other with pistols.  It was difficult to fly a plane and shoot a pistol at the same time, so planes began carrying machine guns.  The planes' propeller blades often got in the way of the bullets. The Germans introduced an interrupter gear that permitted the stream of bullets to avoid the blades.
Later in the war, airplanes were built to travel faster and carry heavy bomb loads.
