British Penetration question

Does anyone know off the top of their head or have the numbers as to how much penetration each British battleship has with its AP and HE? Or is there a way to tell in port how much armor each shell type can pen?

AP: works fine against cruisers, but against BBs they have dismal performance, unless you are shooting at a weaker section of armor.

Thank you Lert! :Smile_Default: Still odd they show pen values in some of their showcase videos but don't have those values displayed in game :Smile_facepalm:

RN BB AP against anything with a semblance of armor is pretty awful, even the 419 AP is terrible.

Considering their short fuse times it has a hard time citadeling ships that aren't cruisers, but it does lead to less overpens though.

Yea i know that British ap is pretty much loaded for cruisers or broadside bbs. I guess my main curiosity was how well HE pens the cruisers.

Working from the WOWS fitting tool which AFAIK uses Fnord Disc's formulae i'll put together a table of all in game BB pen values at 5/10/15/20km rnage bands, probably be posted sometime tomorrow.

Ty for the helpful chart too bad the Hood loses out to the KGV in ranged pen.

Is this HE or AP? The numbers on the high tier ships don't look that bad, but then they do have the short fuse so....

All AP. Also a short fuse might cause a round to detonate inside a ship between the main belt and the citadel if the citadel is internal, but it will never cause it to fail to penetrate. Even at their slowest impact velocities the slowest shells here are still moving around 300m/s. That means they'll move 4.5m or 4500mm before detonating. Thats significantly more than the armour thickness of any plate in the game.

Ap l have found it poor.

Nailed a CA at very close range right on the money and not a single cit in any other BB he was a goner. Happened to me twice yesterday in the limited run l had in Iron Duke obvious cits shots on cruisers and not one cit for a full salvo.

The He on the other hand apparently is loaded with Napalm fire a salvo and spin the wheel 1 to 4 fires every salvo. :Smile_hiding:

Which cruiser, a couple of the frenchies are so bad you can get overpens at extended ranges through the citadel with Pensacola AP because they don't have enough armour to arm the fuse.

Thanks for that. +1.

 

Though I'm confused as to how Ishizuchi's 12in is so much better than Bellerophon's (and Orion's 13.5in).

The Ishizuchi 12in gun is the 305/45 Mk. '10', throwing a 386kg shell at 831m/s.

The Bellerophon 12in gun is the same 305/45 (as far as I can tell, just uses Roman instead of Arabic numerals) weapon throwing a slightly heavier 390kg shell at 831m/s.

The slight weight difference suggests that the Bellerophon is throwing the APC Mk VIa (4crh) while the Ishizuchi is either throwing the APC Mk. VI (2crh) or the CPC Mk. VIIa (4crh) - the second being more likely.

Either way it's most likely that both ships are firing 4crh shells (so similar aerodynamics and energy retention) at similar weight and identical MV.

Yet something gives the Ishizuchi a huge advantage in AP. Krupp was my first thought, but with Warspite vs. Hood the Krupp difference is notable but not on the order of the 36% increase from Bellerophon to Ishizuchi at 10km.

So what gives?

Based on the krupp values, (slightly lower for Bellerophon it looks like Ishizuchi has better drag.

I didn't mean that the fuse would cause it to not detonate, but rather the fuse time maybe is why AP is still considered to be under preforming, even though it has decent pen values at higher tiers.

Ugh, the 419mm/406mm MKII guns still have these comical drag values. This is just pure, pure nonsense. With this sort of performance, why on earth would anyone want the 457mm gun?

Is it worth trying IFHE on a british BB? Might help with pens on cruisers and certainly russian dds.
