Hull Plating measures the damage that a unit can receive in combat before being destroyed.
In combat, ships give and receive damage. The amount of damage a unit can sustain before being destroyed is given by the Hull Plating.
Every unit has a basic value of Hull Plating, which is 1/10th of the ship Structural Integrity (the sum of metal plus crystal used in its production). Besides, each technological upgrade of the Armour Technology gives more 10% of that base value.
It is important to notice that the combat engine gives a probability of a ship exploding proportional to the percentage of the left Hull. This means that a ship can explode even if it still has 50% left of its initial hull (see combat for more detailed explanation on this).
The initial Hull plating of a unit in the beginning of a combat is given by
