During World War II the aircraft, along with the tank and the howitzer, played a vital role in winning a battle or successfully carrying out a military campaign. The German Blitzkrieg could only be conducted with the Luftwaffe air supremacy, which the Third Reich enjoyed during the first two or three years of the war. By 1944, however, the Germans had lost control of the skies over Europe and could not effectively fight against the Allied bombers and fighters and, therefore, lost the war. Not being able to stop the Allied bombers, Germany suffered the systematic destruction of its war industry.
