Demonstrating the point that just as captured aircraft in RAF services did not alwasy carry their 'Air Min' numbers, this Dornier Do.335 was on the strength of the Tactical Test Division at BAS Patuxent River. The '102' on the fin refers to its Werk Nummer, 240102.

Unlike a normal twin-engined aircraft, with wing-mounted engines, loss of an engine on the Do-335 did not cause a handling problem. Even with one engine out, speed was a respectable 621 kph (348 mph). Because of its appearance, pilots dubbed it the "Ant eater" ( "Ameisenbar" ), although they described its performance as exceptional, particularly in acceleration and turning radius. The Do-335 was very docile in flight and had no dangerous spin characteristics. Many Do-335 prototypes were built, as the Reich strained desperately to provide day and night fighters and fast reconnaissance aircraft to the failing war effort. One of the many RLM production plans, issued in December 1943, called for the production of 310 Do-335s by late 1945. Initial production was at the Dornier Manuel plant, but this factory was bombed heavily in March-April, 1944, and the Do-335 tooling was destroyed.

The aircraft was quite large for a single-seat fighter, with a cruciform tail and a tricycle landing gear. The two massive liquid-cooled Daimler-Benz DB-603 engines were used in four different versions, each displacing 44.5 liters (2670 cu in) and weighing 910 kg (2006 lb). The engine produced 1750 hp from 12 cylinders in an inverted V layout using fuel injection and an 8.3:1 compression ratio. The rear three-bladed propeller and dorsal fin were jettisoned by explosive bolts in an emergency, to allow the pilot to bail out safely using a pneumatic ejection seat. The seat, inclined 13 degrees to the rear, was ejected with a force of 20 times gravity. The ventral fin could be jettisoned for a belly landing.

The unconventional layout of the Do-335 -- one engine "pulling" in the nose and another "pushing" in the tail -- was patented by Claudius Dornier in 1937. The configuration provided the power of two engines, but with reduced drag and better maneuverability. The German Aviation Ministry (RLM) was interested in the design, but initially wanted Dornier only to produce bombers. By 1942, Dornier was still continuing design work and the war situation was worsening. The Luftwaffe now needed a multi-purpose fighter, and the prototype Do-335V-1 ("V" indicating "versuchs" or "experimental") flew in fighter form in September, 1943 - six years after its conception. Orders were immediately placed for 14 prototypes, 10 A-0 preproduction aircraft, 11 production A-1 single-seaters, and 3 A-10 and A-12 two-seat trainers.

The Do-335 was one of a small group of aircraft marking the pinnacle of international piston-engined development. It was the fastest production piston-engined fighter ever built, attaining 846 kilometers per hour (474 mph) in level flight at a time when the official world speed record was 755 kph (469 mph). Powered by two 1800-hp engines in a unique low-drag configuration and weighing 9600 kg (21,000 lb) loaded, it was an exceptional heavy fighter. This very innovative design also featured an ejection seat, for pilot safety, and a jettisoning fin.
