Only battleship calibre HE can penetrate their deck armor Henri IV (240 mm) (not worth it, considering how much fire chance you lose) German 203 mm (Hindenburg, Roon, Hipper, Yorck) Moskva, Stalingrad and Petropavlovsk casemate plating Not worth it on 203mm guns, since you lose a lot fire chance just to penetrate this category of armor. Most light cruisers (152 mm, 155 mm, 180 mm)Īll non-German 203 mm ships, and Mogami. German 128 - 150 mm guns (both main and secondary) Tier 7 and lower light cruisers (152 mm, 155 mm) Some destroyers (130 mm - 139 mm, 100 mm super) Light cruisers (152mm) up to and including tier 7 Tier 6 and 7 cruisers' decks, most tier 8 - 10 cruisers' bow/stern, tier 8 - 10 light cruisers' side plating 'Super' refers to the 1/4 HE penetration coefficient. Here are some common armor thicknesses and the minimum HE shell diameters needed to penetrate them, according to the HE penetration formula. THE UPDATE IS QUITE COMPLEX, SOME TIME IS NEEDED TO PROCESS ALL CHANGES.
