[edit] History

The FWD-153 had been developed by the Baade Development Design Bureau in 1953/54. design criteria to meet the demand of Aeroflot (sturdy landing gear, cabin equipment, crew, glass nose for the navigator)


FWD-153A 200 aircraft to be sold up to 1,500 km more efficient than IL-18 (Baade) 30 t MTOW between AN-24 and IL-18 It was forseen to start production in 1962.

two attrappes had been built. In June 1959, the government of the Soviet Union informed the East German side that they would not buy aircraft from East Germany. The design of the FWD-153A had been completed in TBD and the construction of the first prototypes had already begun. In 1959, the technical manager Brunolf Baade decided to abandon the FWD-153 project (including the PTL Pirna 018 engine) in favour of the troubled FWD-152 already in production and the FWD-155.


also known as Dresden 153A, VL-DDR 153A or simply 153A was the first German turboprop passenger airliner. It was developed and tested in Dresden (East Germany) between 1956 and 1961.

The "FWD-153" represents the final development in the Junkers aircraft family which ended with the development planes (Entwicklungsflugzeug - EF).

Baade is the name of the designer of the plane, Brunolf Baade. Only two prototypes for flight were built. The first prototype V1/I (DM-ZYA) was derived from the Samoljot 150 or Alexejew 150 jet bomber designed by former Junkers engineers in the Soviet Union. It included a tandem landing gear and glazed nose for the navigator, which was a common feature in many Eastern Bloc aircraft. The 153A's landing gear was unusual for a passenger plane in that the main gear was housed along the centerline of the fuselage with outrigger wheels in the wing-tips (similar to the more famous Boeing B-47).

The maiden flight of this aircraft took place December 4, 1958. It lasted 35 minutes. The aircraft was lost on its second flight in a crash at Ottendorf-Okrilla while beginning landing approach on March 4th, 1959 taking the lives of the entire crew. The reason or reasons for the crash were never made public, although issues with the fuel system were the most likely cause as the fuel system had never been tested on a tilt. [1]

Test flights continued with the second prototype V4/II (DM-ZYB). This second prototype had a different landing gear configuration, with an unusual configuration of the main landing gear sharing the same pylon as the engines. This aircraft also had abandoned the glazed nose for the navigator.

The third prototype, V5/II (DM-ZYC) only served ground tests.

The flight testing for commercial use was nearly finished by early 1961 with four aircraft in production for the East German state airline Deutsche Lufthansa (later rebranded Interflug). At this time, the East German government stopped all aeronautical industry activties, as the Soviet Union who promoted their own design Tu-124 did not want to buy any of these aircraft nor supported any further development.

All examples of the aircraft were scrapped though currently there is a restoration of the abandoned 153A/II #011 fuselage, which was begun in 1995 at EADS EFW (Elbe Flugzeugwerke GmbH) in Dresden, which is the direct successor of VEB Flugzeugwerke Dresden.
