Ship's hull is what keeps the ship in one piece and protects it's crew from death. If the hull points of a ship reach zero, the ship is destroyed and moved to your Lots ships list (found in Empire-Military).
A ship's durability is determined by the material used in the plating.
- Titanium - durability is based on shiplist.data
- Duranium - 150% durability compared to Titanium plate
- Iridium - 200% durability compared to Titanium plate
