The intent of this video is to review the impact the of the Germans adopting the mk-108 30mm autocannons as the preferred WWII bomber interceptor armament. As WWII progressed the Germans continually up sized their bomber interceptor armament to combat the US (B-17 and B-24) and British heavy bombers. Combat data showed it only took 3 to 5 Mk-108 30mm autocannon rounds to destroy a US bomber, if they could get close enough for the cannons to be effective.
