When the Luftwaffe entered World War 2, its nightfighter force was virtually nonexistent thanks to its leader, Reichmarschall Hermann Goring, who boasted that bombs would never fall on Germany. By mid-1940 his folly was evident; the first night fighter wing was hastily formed with Bf 110s. Initially capable of detecting targets by visual acquisition only, the force greatly improved its effectiveness with the creation of the 'Giant Wurzburg' radar chain.
