The Ta 183 had a short fuselage with the air intake passing under the cockpit

s arranged around the air intake.

It was also possible to carry a bomb load of 500 kg (1,100 lb), consisting of one SD or SC 500 bomb, one BT 200 bomb, five SD or SC bombs or a Rb 20/30 reconnaissance camera. The weapons load would be carried in the equipment space in the bottom of the fuselage and thus partially protrude about halfway from the fuselage, possibly allowing for other armament packages such as the Ruhrstahl X-4 wire-guided missile.

Multhopp's team also seriously explored a second version of the basic design, known as Design III, a modified Design II (it is unknown what Design I referred to). The first of these had only minor modifications, with slightly differently shaped wingtips and repositioning of the undercarriage

. The second version had a reduced sweepback to 32°, allowing the wing and cockpit to be moved rearward. The tail was also redesigned, using a short horizontal boom to mount the control surfaces just above the line of the rear fuselage. This version looks considerably more "conventional" to the modern eye, although somewhat stubby due to the short overall length of the HeS 011.

The second of these two schemes was entered in the official competition ordered by the Oberkommando der Luftwaffe at the end of 1944. On 28 February 1945, the Luftwaffe High Command examined the various Emergency Fighter proposals and selected the Junkers EF128 to be developed and produced; the Focke-Wulf team gained second place. However, in the last few weeks of the war, it was decided that the Huckebein was really the best design and, at a meeting in Bad Eilsen

The MiG-15 does bear a superficial resemblance in layout, sharing the high tailplane, bubble canopy and nose mounted intake and guns, although the aircraft are different in structure, detail shapes and proportions. The MiG-15's design shared features common to fighter designs of that era and were derived from combat experience and aerodynamic considerations (for example, the Republic F-84B/F

This seemed solvable, however, and a newer version correcting these problems was planned. However, the financial crash of 1953, and the fall of Juan Peron
