The Dornier Do 335 Pfeil (Arrow) was a heavy fighter built in later World War II. It was a unique twin engine design with its push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines, and it was considered one of the fastest piston-engined aircraft ever flown.
Sources differ, but only 37 to 48 Do 335s were built and none were known to have flown in combat. The Do 335B-2 was to be a heavily armed Zerstorer (destroyer) with its main feature being two wing mounted 30 mm Mk 103 cannons contained in special fairings with 70 rounds per gun in addition to the normal engine mounted Mk 103 and two 20 mm MG 151/20s in the nose cowl. Due to the increased weight, the B series also standardized on larger tires which required the nose wheel to rotate 45o for stowage during retraction, and an armored windscreen. Less than five Do 335B-2s were in production at the end of the war.
