The EF101 was a carrier aircraft for Mistel operations designed in 1942. The Mistel aircraft was fully integrated into the fuselage and wing of the carrier. The EF101 is a design for the carrier as well as for a new Mistel aircraft, which was based on the Messerschmitt Me109H.
While the Ju88 Mistel design was used as bomber couple, the EF101 was intended to use it on long range survey missions, where the carried aircraft could seperate from its motherplane for further and quicker survey flights. A special tow-in system was developed by Deutsche Forschungsanstalt fur Segelflug - DFS, which should be used for the return to the carrier. This equipment was tested on a Heinkel He177
