The Focke-Wulf Ta 183 Huckebein was a design for a jet-powered fighter aircraft intended as the successor to the Messerschmitt Me 262 and other day fighters in Luftwaffe service during World War II. It was developed only to the extent of wind tunnel models when the war ended, but the basic design was further developed post-war in Argentina as the FMA Pulqui II. The name Huckebein is a reference to a trouble-making raven (Hans Huckebein der Unglücksrabe) from an illustrated story by Wilhelm Busch.

In early 1945, the Reichsluftfahrtministerium (RLM) became aware of Allied jet developments, and were particularly concerned that they might have to face the Gloster Meteor over the continent. In response, they instituted the Emergency Fighter Program, ending production of most bomber and multi-role aircraft in favour of fighters, especially jet fighters. Additionally, they accelerated the development of experimental designs that would guarantee a performance edge over the Allied designs, designs that would replace the first German jet fighters, the Messerschmitt Me 262 and Heinkel He 162.

The result was a series of advanced designs, some using swept wings for improved transonic performance, others instead using the tailless design to lower drag to the same end. Since German aircraft engineers were aware that tailless designs might encounter serious stability problems in the transonic, a variety of stabilization methods such as brakes on the wings were considered for such aircraft or simply adding conventional tail surfaces. Kurt Tank’s design team led by Hans Multhopp designed in 1945 a fighter known as “Huckebein” (a cartoon raven that traditionally makes trouble for others), also known as Project V (Project VI in some references) or Design II at Focke-Wulf.
