All military aviation organizations within or under the control of the RLM of Germany were officially merged in a covert manner to form its Wehrmacht military's air arm, the Luftwaffe.

The Ministry of Aviation was a government department during the period of Nazi Germany (1933–45). It is also the original name of the Detlev-Rohwedder-Haus building on the Wilhelmstrasse in central Berlin, Germany, which houses the modern German Finance Ministry.

The Wehrmacht, were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe. The designation "Wehrmacht" replaced the previously used term Reichswehr and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.

The Luftwaffe was the aerial-warfare branch of the Wehrmacht before and during World War II. Germany's military air arms during World War I, the Luftstreitkräfte of the Imperial Army and the Marine-Fliegerabteilung of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles, which banned Germany from having any air force.
