from Herwig/Rhode "Geheimprojekte der Luftwaffe III"
The EF112 was developed upon a RLM request of 1942 for a quick attack bomber aircraft, which should be used as a support aircraft for ground forces. The estonishing short fuselage of the design contained a single seated cockpit, a bomb bay for 500kg of bombs and two DB603G engines, one in front and one behind of the cockpit, as it was later known from the Dornier Do335. The wing section was mounted on two booms, which were connected via the vertical tail unit in the rear.
The EF112 was proposed to the RLM in December 1942. However, it seems, that this design did not satisfy the RLM and all further work was stopped.
