In order to combat the Mosquito, the He 219 had all excess weight removed. With some weapon and radio systems deleted the aircraft was able to attain a speed of 650 km/h (400 mph). This version was given the designation A-6.
The last major production version was the A-7 with improved DB 603E engines. The A-7 could be outfitted with two 30 mm (1.18 in) MK 108s in the wing roots, two 30 mm (1.18 in) MK 103 cannons and two 20 mm MG 151/20 cannons in a ventral tray, and two 30 mm (1.18 in) MK 108s in a mid-fuselage Schräge Musik installation. The relatively long-barreled MK 103s, however were not usually fitted due to weight considerations.
The follow-on series was to be the He 219B fitted with the new, but very troublesome, 1,864 kW (2,500 hp) Junkers Jumo 222A/B 24-cylinder engines, which would have allowed the He 219 to reach 700 km/h (440 mph), each of which were almost the same displacement as the Double Wasp radial engines in the American P-61 purpose-built night fighter. The He 219B's wing was also to have had increased an increased wing span of 22.06 m (72.38 ft) for better high-altitude performance. The Jumo 222s did not reach production status however, and only a test machine or two were ever fitted for the engines; some additional airframes with the enlarged wing were slated to fly with high-altitude versions of the DB 603. But again, only one or two test machines ever flew in that configuration.
A further adaptation would have been the He 219C, also intended to use the big wing and Jumo 222 powerplants as well as an all-new fuselage of 17.15 m (56.27 ft), with a complete three-man Ju 388J cockpit section forward and a manned power tail turret aft. Day bomber and night fighter versions were proposed and metal was cut for the project but, without the Jumo engines, they never flew.
Paper projects include the very-high-altitude He 219E with a vastly increased wingspan of 28.5 m (93.5 ft) and DB 614 engines, which were apparently an uprated DB 603G capable of 1,491 kW (2,000 hp).
A more reasonable project was the Hütter Hü 211, a design by Wolfgang Hütter that took a standard He 219 fuselage and tail and added a long-span, high aspect ratio wing of 24.55 m (80.54 ft) to create a fast, high-altitude interceptor. Since this design was to be powered by the ill-fated Jumo 222 it never flew, although work continued on two sets of wings until they were destroyed by Allied bombing.
The He 219 was the only piston-engined night fighter capable of facing the British Mosquito on equal terms, given its speed, manoeuvrability and firepower,[1] but it never played a significant role in the war because the industry failed to make it available in sufficient numbers.[2]
