I find it weird that earlier and later versions will have thicker wall considering the hull was left with almost no changes between the different variants.
Yes exactly my issue here… It seems that a 35mm shieldwall after everything produces less spall since there is less residual penetration left in the penetrator, but for the mark 3, since the wall is too thin (but not enough unlike some light vehicles) it produces significantly more spall than it should be…
But just to note: Most vehicles with engine wall gets showered with spall post successful penetration…
AFAIK armor thickness doesn’t matter for spall creation, so whether its 10 or 100mm it will create the same amount of spall, as its tied to projectile itself.
You would need something like 5mm sheet to not create secondary spall with it, while it would be able to absorb most of the spall from previous penetration.
What I meant is… That a round going through the ufp or lfp then transmission and then engine, would not be able to penetrate a 35mm thick plate but will defeat a 10mm plate.
Scenario that would require highly specific conditions, including APDS or other dart coming straight from 8.0 or something. Most projectiles sent your way just overpen entire tank, through lower plate, fuel tank behind it, transmission, engine, bulkhead and exit through rear doors or ammoracks on either side.
So those extra 25mm on bulkhead have no practical impact what so ever, if you were to bump it to 250mm, then maybe it would stop something. Maybe.
