Speed in a heavy is pretty much irrelevant, fully loaded you are slow, contemporary fighters will catch you and the He-177 is no exception, it is barely faster than a B-24.
Speed is in no way irrelevant. Less important, yes, but it still matters.
It carries more ordnance than the B-24, at similar speeds, with strong defenses. If you want more speed, take less ords. You can still carry a good load at high speed.
If heavy opposition is expected then armament is a must and the US bombers will be the best option.
not necessarily. Boston's are more survivable in some cases, because they're damn hard to intercept.
If there is a fighter escort or light opposition then take the He-177.
No, you take whatever you want, because it will probably make it.
If range is an issue then the Lanc.
Range is never an issue. I've start bombed in Ju-88s before. You can get any heavy in the game across the map on a full tank.
But, I cant really compare numbers if the He-177 is not in the game now, can I?
find an original source with a speed chart. There are some.
But the point is that you can make the 177 fit any mission profile, which no other bomber could do in AH. That would make it the most flexible and most used in the game.
Re the Ju-188 it was limited to 2t of bombs IIRC lacking some an internal bay making all ordnance internal, but I would have to look into that. It even has an interesting armament with 2xMG151 a MG131 and a MG81Z, but it is no heavy bomber... The bit of extra speed is nice (I like the guns better), but you will not get away from anyone if the enemy pilot is determined to chase you.
6000lbs for the Ju-188, by a quick trip to wiki. Likely the max was higher, given the Ju-88 could carry 6000lbs, and the 188's weight capacity was higher.
Do 217 could carry 6600lbs internally at 347mph with ok-ish guns. 8800lbs with external mounts.
And the goal isn't to outrun them, its to be fast enough to make it back to base, and execute a high-speed landing before you get caught.
