The Dornier Do 335 Pfeil ("Arrow") was a World War II heavy fighter built by the
Dornier company. The two-seater trainer version was also called Ameisenbär
("anteater"). The Pfeil's performance was much better than other twin-engine
designs due to its unique "push-pull" layout and the much lower aerodynamic drag
of the in-line alignment of the two engines. It was Germany's fastest
piston-engined aircraft of World War II.[2][page needed] The Luftwaffe was
desperate to get the design into operational use, but delays in engine
deliveries meant only a handful were delivered before the war ended.

The first 10 Do 335 A-0s were delivered for testing in May. By late 1944, the Do
335 A-1 was on the production line. This was similar to the A-0 but with the
uprated DB 603 E-1 engines and two underwing hardpoints for additional bombs,
drop tanks or guns. It was capable of a maximum speed of 763 km/h (474 mph) at
6,500 m (21,300 ft) with MW 50 boost, or 686 km/h (426 mph) without boost, and
able to climb to 8,000 m (26,250 ft) in under 15 minutes. Even with one engine
out, it could reach about 563 km/h (350 mph).
