Ar 234 A were prototype variants, partly 4-engined (V6, V8, V13) which had the start trolley. This wasn't a solution for front line units, so the B-Series was started.
Ar 234 B-0: Small series of 13 planes, similar to the projected A series but with retractable landing gear.
Ar 234 B-1: First true Ar 234 series, reconnaisance plane.
Ar 234 B-2: Bomber version, 2 rearward firing MG 151/20, max bomb load 1.500 kg
Ar 234 C-3: 4 engined bomber series, 2 fixed forward firing MG 151/20, 2 rearward firing MG 151/20, ETC 504 bomb racks.
Ar 234 C-4: Reconnaisance version of the C-3.
Some more variants were projected but the protoypes were destroyed at the end of the war:
Ar 234 C-5: 4 engined, 2 seater bomber.
Ar 234 C-6: 4 engined, 2 seater reconnaisance plane
Ar 234 C-3N, C-7, P: Night fighter
The only Ar 234 that was used as a night fighter was a Ar 234 B-1 which had a belly gondola with 2 MG 151/20. It shot down several heavies in the winter of 44/45.
