I must say that events when a capital ship is blown up after the first hit are not that rare. But most times its by a huge shell penetrating the main turret armour, so it is understandable. However I dont see a way how can a whole 6in shell get through 1,5in of deck armour at that time (even 13in is not able to do so) to be able to explode right above the armoured deck. I missed the deck thickness in the screenshot in the OP. Since RTW1 it's been the case that any armor short of 2" thickness is vulnerable to splinter penetration even if it stops the shell itself (or sometimes if it doesn't even hit the armor. I've had shell bursts in the superstructure cause machinery damage from splinters on thin-deck CLs). I don't use armor less than two inches except on CLs (for the deck) and 5" (rarely 6") secondaries. With 1.5" decks, you get splinter penetration from 4-6" guns occasionally, with 1" it's routine. 2" is, per the manual, splinter-proof. Yeah, I know that. But it is a battleship, it has armored cruiser scheme, not protected cruiser. I doubt that the shell penetrated the upper deck. And if it didnt, then there is no way for splinters to penetrate 2 decks - upper deck first and then the main citadel armor.

At 6,840 yards I'd be somewhat surprised if the shell trajectory would allow a 6" shell to hit both the upper (splinter) and the lower (main) armor decks; seems more likely to me that this is a hit that somehow or other found a path to the main armor deck that bypassed other parts of the ship's armor.

And if it didnt, then there is no way for splinters to penetrate 2 decks - upper deck first and then the main citadel armor. As far as I know (unless there's a contravening quote from one of the devs) RTW only models one layer of deck armor (except on carriers with armored flight decks). Even if it does, I would expect the deck thickness dropdown to specify the total thickness of all layers together. So if it takes 2" of armor to stop a splinter, and the total thickness of all your decks together is 1.5", then you are vulnerable to splinter penetration, period. Now, what I don't know is what the physical rationale is for the blanket 2" requirement to stop splinters, regardless of the caliber of the originating shell. It seems like it may just be a simplification with no physical rationale, in which case it would tend to over-favor splinter penetrations from 4" or 6" shells (as in this case), and under-favor penetrations from 16" or 20" shells. Or there may be some solid physics behind it, I don't know. Anybody care to chime in on the ballistics of splinters in armor?
