The unusual tandem-engined layout used in the Pfeil was first patented by Dr Claude Dornier in 1937, but it was not until the end of 1942 that permission to build a prototype fighter with tractor and pusher DB 603 engines was given. However the Pfeil was never encountered in operations, although available in small numbers as the Do 335 A-1 single-seat fighter (with a maximum speed of 763km/h), Do 335A-6 two-seat night fighter and Do 335 B-series heavy fighter and night fighter towards the end of the war.
Well ,i love this plane because of its speed. In Il2-Sturmovik simulator no allied plane can overtake the pfeil. It looks hilarious when 3 spitfires are on your six and can't get you :D
In his book The Big Show, French ace Pierre Clostermann writes about an encounter with DO335 in 1945. According to his account, while on combat patrol Clostermann opened fire from his Tempes on a single DO 335 which then accelerated and fled. In his official report he described the aircraft quite accurately mentioning cruciform appearance of its tail and push-pull engines. According to Clostermann, intelligence later identified the aircraft as DO 335. This indicates the aircraft could have been used operationally in small numbers.
It never did see combat, in the strictest sense, but it is known a squadron of British fighters over Germany encountered an unarmed Do 335 prototype. Before they could react, the 335 escaped at high speed and the British were unable to pursue.
