Concept note-1: -After the defeat of Germany, the service was dissolved on 8 May 1920 under the conditions of the Treaty of Versailles, which also mandated the destruction of all German military aircraft. Since the Treaty of Versailles forbade Germany to have an air force, German pilots trained in secret.
Concept note-2: -After World War II, German aviation was severely curtailed, and military aviation was completely forbidden after the Allied Control Commission disbanded the Nazi-era Luftwaffe in August 1946.
Concept note-3: -Yes, Germany is allowed to establish armed forces for solely defense but is limited to the German Army, German Soldiers, German Navy, and German Air force. It is also not allowed to have biological, chemical, or nuclear weapons.
Concept note-4: -By the time of the Normandy invasion, the Luftwaffe was unable to mount anything other than a token response to Allied air forces which had achieved air supremacy. The underlying causes for this situation were the insufficient numbers of planes, low levels of pilot training and outdated aircraft.
Concept note-5: -Germany had been without armed forces since the Wehrmacht was dissolved following World War II. When the Federal Republic of Germany was founded in 1949, it was without a military. Germany remained completely demilitarized and any plans for a German military were forbidden by Allied regulations.
