Submarines can operate invisibly to enemy units because they travel beneath the waves. They remain invisible until they attack a surface ship, after which they again disappear. However, other submarines and AEGIS Cruisers and Destroyers can see them plainly. In addition, Submarines have Stealth Attack. A coastal city needs oil in its Strategic Resource box to build a sub.
