But I don’t recall the dive bomber being really effective in the SBR role…
The Stuka ju-87 bombed most of the cities in the early period of the war. They bombed cities ahead of attacking troops, taking out factories, buildings etc…
They were used in the Battle of Britain to do the same and experienced many loses. They were not for dogfighting. They were not used like conventional bombers, but were utilized in destroying the same types of buildings but were used in daylight ( most models). A divebomber can bomb most anything except it only has one bomb so it must count.
I value this at 50% rate of damage to account for the quantities. So they are less effective than bombers, but i dont think it should be like 23.5% for AA you got to round things up or down.
The idea of divebomber also includes light bombers classes in some cases where some of these were used in the same role.
Its a nifty concept to get a few of these if your a poor nation and cant afford 12 IPC, you can buy a 8 IPC plane and still have a little sbr.
