クルト・タンク
In response to the RLM guidelines of 22 January 1942, Kurt Tank of the Focke-Wulf company designed the Ta 400 as a bomber and long-range reconnaissance aircraft, to be powered by six BMW 801D radial engines, to which two Jumo 004 jet engines were later added. Design work was begun in 1943, much of it being carried out by French technicians working for Focke-Wulf at Châtillon-sous-Bagneux near Paris, with contracts for design and construction of major components being awarded to German, French, and Italian companies in an attempt to speed the process and begin construction of prototypes as soon as possible.
