German Anti-Aircraft Guns

German anti-aircraft guns were produced massively, especially during the last three years of the WW2, to protect their cities and industrial complex against Allied air raids. Therefore, the Wehrmacht deployed heavy and light anti-aircraft guns to prevent their arms factories from being destroyed by American and British bombers. The heavy anti-aircraft guns ranged in calibers from 88 to 128mm, which were powerful enough to shoot down Allied bombers flying at high altitudes; the second ones were 20-to-50mm guns used against medium and low-flying Allied planes, such as ground attack and fighter aircraft.

These German guns were deployed on the outskirts of big cities, industrial areas, and military camps perimeters. The most massively produced and used was the 88mm AA gun, which was also employed in the anti-tank and anti-bunker role. They had the official designation of "Flak", which is the German acronym for "Flugabwehrkanone" ("air defense canon"). Despite the fact that most of them were excellent weapons, and manufactured by the thousands, they could not stop the enemy bombing raids on German cities and factories once the Allied had won air supremacy over the Luftwaffe.
