(1:285) Junkers/Doepp Rocket Fighter

The 2013 issue of the German "Flieger Kalender" features an article about an early concept for a rocket fighter, proposed by Philipp von Doepp in 1932 with a detailed report. Von Doepp was working then for the "Forschungsanstalt Professor Junkers", so this concept can be regarded as a Junkers concept. It was intended to be powered by five rocket engines, all of them used for the vertical take-off, but only by two for cruising flight. Interestingly at least some of the nozzles or engines were intended to be movable and so that's an early example for thrust vectoring ! The plane would have been armed with two guns and was to have been used as a short range interceptor. It seems, the achievable thrust from those quite small engines was somewhat over- estimated, as with an MTOW of 2.330 kg a maximum altitude of 15.000 m should have been reached in 53 s with a speed of up to 1.080 km/h.
Nevertheless, it is said, that this concept more or less was the basis for the other early German rocket fighter designs, like the He 176, von Brauns rocket fighter or the Fi 166.
