The 88mm anti-aircraft gun is a medium caliber anti-aircraft gun designed and tested by the world-renowned artillery manufacturer Krupp subsidiary in Germany. After completing on-site testing, it entered service in 1933 and also possessed particularly strong anti tank capabilities. This gun was the most successful artillery system used during World War II, a highly successful medium caliber anti-aircraft gun that gave it a high firing rate. After Hitler finally freed himself from the constraints of the arms limitation treaty, the 88mm anti-aircraft gun was immediately adopted by the German Air Force (whose air defense forces were under its jurisdiction) as the standard equipment for medium caliber anti-aircraft guns.
