The Development of the German Air Force, 1919–1939

The Development of the German Air Force, 1919 to 1939, first published in 1968, written by Professor Richard Suchenwirth, and revised and edited by Mr. Harry R. Fletcher, is one of a series of historical studies written for the United States Air Force Historical Division by men who had been key officers in or outstanding authorities on the German Air Force during World War II.
The overall purpose of the series is twofold: 1) To provide the United States Air Force with a comprehensive and, insofar as possible, authoritative history of a major air force which suffered defeat in World War II, a history prepared by many of the principal and responsible leaders of that air force; 2) to provide a firsthand account of that air force's unique combat in a major war, especially its fight against the forces of the Soviet Union.
This series of studies therefore covers in large part virtually all phases of the Luftwaffe's operations and organization, from its camouflaged origin in the Reichswehr, during the period of secret rearmament following World War I, through its participation in the Spanish Civil War and its massive operations and final defeat in World War II, with particular attention to the air war on the Eastern Front.
