Operation Pointblank was a WWII joint Anglo-American operation intended to severely degrade and/or eliminate German aircraft fighter strength.
The Americans used multiple groups of Boeing B-17 Flying Fortress aircraft during the operation.
Operation Pointblank used a strategy of attrition against defending German air forces and was a success. During the campaign, a crucial tactical change was made which was providing fighter escorts to the bombers. The attainment of the operation's key objectives was critical because the Western Allied forces invasion of France required air superiority.
