By then ground-attack versions of the Focke-Wulf Fw 190 had largely replaced the Stuka, but Stukas remained in service until the end of the war. An estimated 6,500 Ju 87s of all versions were built between 1936 and August 1944.

During this era, the majority of aircraft designers were relatively conservative and, save for some isolated examples, no advancements were achieved; according to aviation historian Charles Gibbs-Smith, the pioneering work of Hugo Junkers was a notable exception.
