The Junkers Ju 288, originally known within the Junkers firm as the EF 074, was a German bomber project designed during World War II, which only ever flew in prototype form. The first aircraft flew on 29 November 1940; 22 development aircraft were eventually produced.The Ju 288 was the winner of the Bomber B contest, although the contest was started by the Junkers firm's submission of the EF 074 and their selection was never really in doubt. The Bomber B concept of a Schnellbomber was originally intended to replace the Junkers Ju 88. The Ju 288 offered a design that was larger, offered cabin pressurization for high altitude missions, had longer range, a much greater bomb payload, was even faster, and had improved defensive firepower. The design was intended to replace all the bombers then in Luftwaffe service.Delivering all of these requirements in a single airframe demanded much more powerful engines; all of the Bomber B concepts, at one time or another, relied on the Junkers Jumo 222 engine to deliver this power. Ultimately, the Jumo 222 was a failure in spite of massive effort and several redesigns over a period of several years, with nearly 300 development prototypes produced. No suitable replacement was ever forthcoming, dooming the Ju 288 program, and leaving the Luftwaffe with older bomber designs during the second half of World War II.
