Armor & Protection (War on the Sea)

Here is some information about the armor & protection in War on the Sea:
== armor & protection ==
War on the Sea incorporates detailed ballistics and damage systems. Each gun type is individually modeled based on historical data, specifying range, muzzle velocity, calibre, and armor penetration characteristics. These parameters prioritize historical accuracy over game balance. Wind is omitted for simplicity in the ballistics model.
== SHELL PENETRATION ==
Armor serves to safeguard vital systems from impacts, represented by the thickness of armor plating in a specific ship region (in inches or millimeters). Factors like material, armor quality, and slope influence its effectiveness. A sloped angle enhances deflection, making armor more effective without requiring increased thickness. Ship hulls have two armor values: belt (vertical) and deck (horizontal), offering protection from side hits or hits from above. Superstructure regions and gun turrets possess a single armor value.
== SHELL HITS ==
Several factors determine shell penetration:
* Calibre: Larger shells penetrate thicker armor.
* Muzzle Velocity: Higher velocity enhances armor penetration.
* AP Shell: Armor-piercing shells, despite having a smaller explosive warhead, penetrate armor about 5 times better than a similar-calibre HE shell.
* Striking Angle: Shallow angles may cause shells to bounce away (ricochet).
* Short Range: Shells with higher velocity may punch through belt armor but ricochet off deck armor.
* Long Range: Shells with a steep trajectory may ricochet off belt armor but penetrate deck armor (plunging fire).
== DAMAGE DEALT BY SHELLS ==
When an AP shell strikes armor, the following outcomes may occur:
* If the shell calibre is greater than 14 times the armor thickness, it automatically penetrates, causing full damage.
* If the shell penetrates the armor, it explodes, causing full damage.
* Shallow angle strikes result in deflection (ricochet), causing 20% damage.
* If the shell fails to penetrate armor, it explodes externally, causing only 20% damage.
HE shells deal an additional 25% damage. They can penetrate armor but are only as effective as an AP shell about 1/5th of their calibre. Hits to unarmored ship parts or when the shell calibre exceeds 14 times the armor thickness automatically penetrate and cause full damage.
== TORPEDO DEFENSE SYSTEMS ==
Torpedoes, delivering a substantial warhead below the waterline, are potent sea weapons. Larger ships may have a Torpedo Defense System (TDS) integrated into their hull. When hit, the TDS is destroyed, rendering it ineffective against subsequent hits to the same ship region. TDS is indicated as a percentage value and is typically present in the outer hull's mid-section. Upon a torpedo hit to a compartment with TDS:
* Chance for damage to neighboring compartments is halved.
* All damage dealt by the torpedo is reduced by the TDS value.
* TDS value of the hit compartment and its neighbors is permanently reduced to 0% due to the torpedo impact.
