Bomber B was a German military aircraft design competition organised just before the start of World War II to develop a second-generation high-speed bomber for the Luftwaffe. The new designs would be a direct successor to the Schnellbomber philosophy of the Dornier Do 17 and Junkers Ju 88, relying on high speed as its primary defence. Bomber B would also be a much larger and more capable aircraft, with range and payload far greater than the Schnellbombers, besting even the largest conventional designs then under consideration.
