On 23 November 1943, the V3 prototype, which was also the first to be powered by the Jumo 211R engines and carry radar apparatus, made its first flight. The added weight of the guns and drag of the 32-dipole element Matratze radar antennas used on its UHF-band FuG 212 C-1 Lichtenstein radar unit slowed the aircraft by a full 75 km/h, although it was still somewhat faster than the He 219. The rest of the 15 prototypes were then delivered as A-0 models, identical to the V3. Some of these also included a raised canopy for better vision to the rear.
