The Dornier Do 335 was a twin-engined fighter designed for the German Luftwaffe during the closing stages of the Second World War. The engines were arranged in a push-pull configuration, which produced a very fast aircraft. Overheating was a constant threat from the rear engine, a problem that continued throughout its development.
By the end of the war, no Do 335s had been delivered to operational squadrons. At leat 16 prototypes were built, along with approximately 22 pre-production machines completed. These included A-0, A-1 and A-11 versions. Numerous options were under development including a night fighter and twin fuselage versions.
Post war, captured aircraft were evaluated by France, Britain and the US.
