The Fokker D.23 was a revolutionary design of a push-pull twin engined fighter, with nose gear. In an attempts to reduce frontal surface Fokker placed the engines in a tandem configuration. To reduce weight Fokker used the Czech air cooled Walter Sagitta engines, which didn't need a heavy cooling system. The aircraft survived the German invasion in 1940 and was studied by the Germans. In 1943 Dornier produced the Dornier Do 335 Pfeil which had a similar configuration.
