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 had been developed only to the extent of wind tunnel models when the war ended, but the basic design was further developed postwar in Argentina as the FMA IAe 33 Pulqui II. The name Huckebein is a reference to a trouble-making raven (Hans Huckebein der Unglücksrabe) from an illustrated story in 1867 by Wilhelm Busch. Development In early 1944, the Reich Air Ministry (RLM, for Reichsluftfahrtministerium) 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 which took effect on July 3, 1944, 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 Schwalbe and Heinkel He 162 Spatz. 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 at transonic speeds, much as the prototype Me 163B V18 did on July 6, 1944, in hitting a record 1,130 km/h (702 mph) top speed and nearly destroying its entire rudder surface in the process, a variety of stabilization methods such as airbrakes 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" (from Wilhelm Busch's "Hans Huckebein, the unlucky raven", 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. The raven character itself was re-used for the modern Bundeswehr's Lufttransportgeschwader 62 as the inspiration for their unit's insignia. Design Development of the Ta 183 started as early as 1942 as Project VI, when the engineer Hans Multhopp assembled a team to design a new fighter, based on his understanding that previous Focke-Wulf design studies for jet fighters had no chance of reaching
