Bombs: 1,000 kg (2,200 lb) bombs carried internally
I think Maximal Bomb load 1,000 kg would be Br 4 i think lower Bomb load could be Br 3 maybe 3x 250 Kg = 750 Kg or the Do 215B-1 as a reconnaissance bomber, a 500 kg bomb i think this would be Br 2? Do 17 - Weltkrieg2 in the link is info about the D0 215 as well!
Internally carried bombs, so then due to weight distribution it would always carry an even number of bombs unless carrying a singular maximum load bomb. But that would be… unusual for this aircraft.
Remember it is not just bomb load or armament that dictates BR rating.
Speed and handling also factor. This plane is probably going to be BR III with any load.
Do 215 (Do 17 Z-7 as its already in game, and the 215 is just the export model of the Do 17 Z)
A quick comparison of stats show this is a real hunk of Junk, personally I would look to add it at BR2 with 10 x 50kg bombs, Also instead of the Do 215, Id seek to add the Do 17 instead, as that was a mainline production aircraft instead of just the export model.
It was the interest shown by Yugoslavia in the Do 17Z which gave rise to the designation Dornier Do 215, allotted for no apparent reason to the Do 17Z sent to Yugoslavia for demonstration purposes in July 1937.
While this aircraft was essentially identical to the production Do 17Z, the Reichsluftfahrtministerium assigned the designation Do 215 to the export version.
Its still the exact same plane. Not to mention we already have a Do 17Z model ready to use, so why complicate it for 0 reason? Also also, why use the obscure export name instead of the actual designation? Especially for such an iconic german bomber of the war?
