 The Ta 183's flying surface design was distinguished by a 40˚ swept-wing and T-tail (characterized as the "Multhopp T-tail", whose "elevator" surfaces were only used for "elevator trim" - the ailerons were actually used as elevons, due to the wings' sweepback placing them laterally opposite the jet engine exhaust) was the winner of the Luftwaffe's 1945 Emergency Fighter Program.However, due to the deteriorating war situation, delays in development meant that only wind tunnel models had been completed by the time of Germany's surrender.Although David Myhra among other historians claim that the post-war Soviet MiG-15 was based on the Ta 183, modern experts in Russian and Soviet aviation history such as Yefim Gordon reject this, although acknowledging that some of the captured data from Multhopp's design work was examined by Artem Mikoyan and Mikhail Gurevich in the formative study of contemporary research.
