 During World War I the Central Powers became increasingly unable to meet the Allied Powers in terms of outright number of fighter aircraft.To overcome this shortcoming rather than deploying their fighters uniformly along the fronts, the Germans concentrated their fighters into large mobile Jagdgeschwader formations, the most famous of which was Manfred von Richthofen's Flying Circus, that could be moved rapidly and unexpectedly to different points along the front.This allowed them to create a "local superiority" in numbers, that could achieve air supremacy in a local area in support of ground operations or just to destroy Allied fighters in the overall strategy of attrition.
