Naval warfare is conducted by ships which operate in the world's interconnected seas and oceans. Naval power is key to protection of convoy traffic, or disruption of enemy convoys. Control of the sea can facilitate naval invasions, or prevent the enemy from performing an invasion of their own. Ships can influence land combat by performing shore bombardment, or block straits to impair enemy movement.
As naval warfare is a complex topic, it is divided among multiple articles. This page serves as a hub, providing a list of the articles which are relevant to naval warfare.
- Main article: Navy
A navy is a country's collective naval force. It is divided among task forces, fleets and theaters.
- Main article: Ship
Navies are fundamentally composed of ships.
- Main article: Naval missions
Naval warfare is primarily conducted through naval missions, which may be assigned to task forces.
- Main article: Naval battle
When two opposing navies meet, a naval battle unfolds.
- Main article: Naval technology
Advances in naval technology can unlock more capable ship designs, or improve the performance of existing ships.
- Main article: Naval doctrine
Naval doctrines provide bonuses for specific forms of naval warfare.
Mines have powerful effects, and the AI currently pays little attention to mines. They will only perform minimal minesweeping efforts at most, regardless of how many mines there are. It is thereby possible to gain a strong naval advantage over the AI through extensive mining. The resulting naval supremacy can be useful for facilitating naval invasions, as well.
Due to their stealth and low cost, submarines are well suited for minelaying. When equipped with minelaying tubes and given an engagement rule of 'Never engage', they can perform minelaying missions with near impunity. They remain vulnerable to naval bombers and may take some losses this way, but in practice the AI does not perform enough bombing of minelaying submarines to pose a problem for the player.
Some countries start the game with primitive submarines based upon the 'Early Submarine Hull'. Retrofitting these submarines as minelayers can be a good way to put them to use, as their low combat performance will not affect their ability to lay mines.
Strike force composition
To ensure that the capital ships are protected from torpedoes, it is prudent to have sufficient screens in the strike force to achieve full screening efficiency. While four screens per capital ship are required for full efficiency, it can be beneficial to have even more screens in the strike force than this, to ensure that screening efficiency remains high even if a few screens are destroyed in battle.
