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. It was similar to the A-0 but with the up rated DB 603E-1 engines of some 1,324 kW (1,800 PS) take-off power rating apiece on 87 octane "B4" lignite-derived synthetic fuel,[6] and two under wing hard points for additional bombs, drop tanks or guns. It had 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 climbed to 8 000 m (26 250 ft) in under 15 minutes. Even with one engine out, it reached about 563 km/h (350 mph).[citation needed]
Delivery commenced in January 1945. When the United States Army overran the Oberpfaffenhofen factory in late April 1945, only 11 Do 335 A-1 single-seat fighter-bombers and two Do 335 A-12 trainers had been completed.
French ace Pierre Clostermann claimed the first Allied combat encounter with a Pfeil in April 1945. He describes leading a flight of four Hawker Tempests from No. 3 Squadron RAF over northern Germany, when he intercepted a lone Do 335 flying at maximum speed at treetop level. Detecting the British aircraft, the German pilot reversed course to evade. Despite the Tempests' considerable low altitude speed, the Royal Air Force fighters were not able to catch up or even get into firing position.
