* While the Ar-234 was conducting reconnaissance and bombing operations in defense of the Reich, the type was still being modified and improved. One enhancement was a field modification. A few Ar-234Bs were pressed into service as night fighters by being fitted with FuG 218 "Neptun" longwave radar, featuring nose-mounted aerials, and a belly pack containing two 20 millimeter MG-151/20 cannon. The radar operator was crammed into the fuselage behind the wing. There is no evidence that any of these few improvised Ar-234B night fighters ever scored a kill.
