Fokker Eindecker fighters
The Fokker Eindecker fighters were a series of German World War I monoplane single-seat fighter aircraft designed by Dutch engineer Anthony Fokker. Developed in April 1915, the first Eindecker ("Monoplane") was the first purpose-built German fighter aircraft and the first aircraft to be fitted with a synchronization gear, enabling the pilot to fire a machine gun through the arc of the propeller without striking the blades. The Eindecker gave the German Army's Air Service (then the Fliegertruppen des deutschen Kaiserreiches) a degree of air superiority from July 1915 until early 1916. This period, during which Allied aviators regarded their poorly armed aircraft as "Fokker Fodder", became known as the "Fokker Scourge".

A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes.
