Udet went so far as to advocate that all medium bombers should have dive-bombing capabilities, which initially doomed the only dedicated, strategic heavy bomber design to enter German front-line service during the war years — the 30-metre wingspan He 177A — into having an airframe design (due to Udet examining its design details in
