Naval intelligence

Naval intelligence refers to the gathering and distribution of information relevant to a nation's navy. It is used to predict an enemy fleet's movements and intentions, and how to counter their plans. It can also consist of attempts at discovering a particular cipher either through observations, code-breaking specialists, or theft or recovery of parts of an enemy's cipher machine from a ship after boarding. This can also be collected from planes, spies, submarines, divers, and other methods.

With proper naval intelligence, an admiral or naval officer will be able to outmanouver and manipulate the opposing forces.
