Junkers Ju 87 Stuka was obsolete in what was now a fighter-bomber's war. The Bf 109 and Fw 190 could at least fight enemy fighters on equal terms after dropping their ordnance but the Stuka could not. The Ju 87's vulnerability was demonstrated on 11 November 1942, when 15 Ju 87 Ds were shot down by United States Army Air Forces (USAAF) Curtiss P-40Fs in minutes. By 1943, the Allies enjoyed air supremacy in North Africa. The Ju 87s ventured out in "Rotte" strength only, often jettisoning their bombs at the first sight of enemy aircraft. Adding to this trouble, the German fighters
Junkers J 2 fuselage framing, primarily as an engineering exercise, were finished shortly before the end of 1916. It is also thought that the contrasting promise of the advanced, low drag features of the Junkers monoplane aircraft designs, versus the Junkers firm's usage of experimental non-traditional sheet metal materials, and the firm's habit of almost constant experimentation obstructing any future hope of producing its advanced designs for the "Luftstreitkräfte", compelled "IdFlieg" to create the "Junkers-Fokker Aktiengesellschaft", abbreviated as "Jfa" and pronounced as if spelled "iefa" in German, on 20 October 1917, to allow Anthony Fokker, who even flew one of the J 2
