9The 8.8cm Flugzeugabwehrkanone 18/36/37/41 - more popularly known as the 'Flak 88' - was one of the most successful and influential artillery gun types in the German arsenal in the Second World War. Developed during the 1920s and 1930s, the gun combined accuracy, a high muzzle velocity and a rapid rate of fire (15-20rpm). Although at first developed as an anti-aircraft gun, it went on to achieve equal repute as an anti-tank weapon, imposing horrific casualties on Allied armor across all major European and North African theaters of war. In one clash in Normandy, in June 1944, for example, a single Luftwaffe 8.8cm battery destroyed some 40 Allied tanks.
