Armour Technology is an essential part of building your empire. Every time you upgrade your Armour Technology, you add 10% of the base strength to the hull plating of your fleet and defence, making it a very important technology to research. Due to the fact that metal is the most abundant resource in the universe, massive stock levels can be easily built up, allowing the player to further research this technology to a high level. This is the only research technology that uses metal alone, therefore spare metal can be stored in order to facilitate the research.
