Passage: Army Group B had the support of 1,815 combat, 487 transport and 50 glider aircraft and another 3,286 combat aircraft supported Army Groups A and C. The Luftwaffe was the most experienced, well-equipped and well-trained air force in the world. The combined Allied total was 2,935 aircraft, about half the size of the Luftwaffe. The Luftwaffe could provide close support with dive-bombers and medium bombers but was a broadly based force, intended to support national strategy and could carry out operational, tactical and strategic bombing operations. Allied air forces were mainly intended for army co-operation but the Luftwaffe could fly air superiority missions, medium-range interdiction, strategic bombing and close air support operations, depending on circumstances. It was not a Panzer spearhead arm, since in 1939 fewer than 15 percent of Luftwaffe aircraft were designed for close support as this was not its main role.
