The National Socialist Flyers Corps (German: Nationalsozialistisches Fliegerkorps; NSFK) was a paramilitary organization of the Nazi Party that was founded in the early 1930s during the years when a German Air Force was forbidden by the Treaty of Versailles. The organization was based closely on the organization of the Sturmabteilung (SA) and maintained a system of paramilitary ranks closely associated with the SA. A similar group was the National Socialist Motor Corps.
During the early years of its existence, the NSFK conducted military aviation training in gliders and private airplanes. When Nazi Germany formed the Luftwaffe, many NSFK members transferred. As all such prior NSFK members were also Nazi Party members; this gave the new Luftwaffe a strong Nazi ideological base in contrast to the other branches of the German military, who were composed of "Old Guard" officers from the German aristocracy.
The National Socialist Flyers Corps continued to exist after the Luftwaffe was founded, but to a much smaller degree. During World War II, the NSFK mainly performed air defense duties such as reserve anti-aircraft service.
