Extended version of the IFHE changes:
Reasons behind the changes:
To simplify interactions between same-tier cruisers. For example, HE shells fired by cruisers with 152–155 mm guns should be capable of penetrating the plating of same-type ships without the effects applied by any extra conditions. These changes are aimed at shifting the Inertia Fuse for HE Shells skill out of most players' first-choice set of skills.
To improve the durability of cruisers in battle: changes to cruisers' plating thicknesses will make these ships more resistant to battleship salvos if positioned wisely.
To enhance the distinction between cruisers carrying guns with a caliber of, or exceeding, 190 mm, and cruisers with 149–189 mm guns, by changing their armor protection: the former will feature thicker armor for their central "box," while the latter will have thicker armor only for the central part of their decks.
To keep the armor protection of battleships as it is: without the Inertia Fuse for HE Shells skill applied, cruisers with 152–155 mm guns will continue to be unable to penetrate the plating of same-tier battleships.
We wanted to balance the Inertia Fuse for HE Shells skill in such a way that the combination of its positive and negative characteristics would influence players' choices, making the skill less of an ultimate "go-to" option when training Commanders.
We'll keep a close eye on how these changes affect the game balance and battle performance of certain ships. If required, additional balance corrections will be applied to the skill and some ships to preserve their battle performance.
Changes to the Inertia Fuse for HE Shells skill:
The bonus applied to the armor-penetration capabilities of HE shells has been changed from 30% to 25%.
The skill will now reduce the chances of causing fire by half, instead of subtracting 1% or 3% from them, depending on the caliber. It is only the standard chances of fire being caused by HE shells that are reduced by half. Other bonuses to the chances of causing fire will function as before, such as the bonuses provided by the Victor Lima signal or Demolition Expert skill.
Example: the standard chances of fire being caused by HE shells for cruiser Helena are 12%. With the Inertia Fuse for HE Shells skill mastered, the chances of causing fire are reduced to 6%. With the Demolition Expert skill, the chances increase to 8%.
This skill previously provided a significant advantage with a minimal penalty, which made it too impactful. The updated version of the skill brings it more in line with the efficiency of other skills.
The rules for calculating armor-penetration have been changed for all HE and SAP shells: a new rule—"a shell penetrates armor if the armor-thickness value is less than or equal to the shell-penetration value"—will now be applied instead of the old rule—"a shell penetrates armor if the armor-thickness value is strictly less than the shell-penetration value." For example, 152 mm shells fired from a Tier VII cruiser will be able to penetrate armor plating with a thickness of up to 25 mm, as opposed to the 24 mm it used to be.
The armor-penetration capacity of HE shells of Tier VIII–X cruisers carrying 152–155 mm guns, which was previously calculated in accordance with the 1/6-caliber rule, will now be calculated following the 1/5-caliber rule. When firing HE shells, these ships will be able to penetrate each other's armor plating, as well as the plating of Tier VIII–X cruisers that is up to 30 mm thick, without use of the Inertia Fuse for HE Shells skill.
Changes to cruiser and battleship armor protection
The changes to cruisers' plating will make these ships more resistant to fire from battleships when positioned wisely: AP shells will ricochet off the plating if they impact at a sharp angle. Tier X cruisers already benefit from adopting the proper positioning. At the same time, the central parts of the hulls and decks of cruisers carrying guns with a caliber of 190 mm or more now have thicker armor, while cruisers with guns of a smaller caliber have thicker armor only for the central parts of their decks. These changes emphasize the distinction between light and heavy cruisers.
Detailed data on the armor-plating thickness of cruisers is presented in the table below.
Due to changes to the rules for calculating the armor penetration of HE and SAP shells, the armor plating of Tier VI–VII battleships has been changed to 26 mm in order to keep interactions between ship types consistent.

(armor thickness that the shells can penetrate without the Inertia Fuse for HE Shells skill) 180 mm 29 mm 30 mm (can penetrate the plating of same-tier cruisers) 152 and 155 mm (Tier VIII–X cruisers) 24 mm (unable to penetrate the fore and aft ends of same-tier cruisers) and 25 mm 30 and 31 mm (can penetrate plating of same-tier cruisers) 150 and 152 mm (Tier I–VII ships) 24 mm 25 mm (can penetrate the plating of same-tier cruisers) 150 mm (German ships, except destroyers) 37 mm 38 mm (can penetrate the plating of same-tier battleships) 128 mm (German ships, except destroyers) 31 mm 32 mm (can penetrate the plating of same-tier battleships) 113 mm 18 mm (unable to penetrate the plating of same-tier destroyers) 19 mm (can penetrate the plating of same-tier destroyers) 100 mm (Japanese Tier VIII–X ships)* 24 mm (unable to penetrate the fore and aft ends of same-tier cruisers) 30 mm (can penetrate the plating of same-tier cruisers) * This change to the penetration of shells of this caliber has been made without compliance with the new rule for calculating the penetration of HE and SAP shells. The reason behind increasing this value is that the 100 mm shells of Japanese ships always acted in a similar manner to the 152 mm shells of Tier VIII–X cruisers in terms of their armor-penetration capabilities. Apart from that, the armor penetration of the 105 mm HE secondary battery shells fired by Yorck, Prinz Eitel Friedrich, Scharnhorst, Scharnhorst B, Gneisenau, Admiral Graf Spee, and HSF Admiral Graf Spee was increased from 18 to 26 mm. Earlier, we had already increased the armor penetration of the 105 mm secondary battery shells fired by König, Bayern, Bismarck, Tirpitz, Graf Zeppelin, Graf Zeppelin B, Prinz Eugen, Admiral Hipper, Roon, and Hindenburg to 26 mm.
