- This page deals with the mechanics associated directly with naval units.
For naval combat mechanics and fleet organization see naval warfare.
This article describes the different naval units and the statistics associated with them along.
There are five main types of ships: capital ships, carriers, screens, submarines, and convoys. Ships are organized into fleets. Each fleet contains a minimum of one ship and no maximum limit.
As the main surface combatants capital ships are designed to sink enemy ships. They are expensive and require long time to build so make sure to protect them with enough screens.
- Super Heavy Battleships (SH-BB): These fantastically huge (and expensive) behemoths exaggerate all of the characteristics of more reasonably-sized battleships, to which end their efficiency lies in literally outliving other Battleships. One of these never gets old, with 1940 variant being redundant form of "overkill".
- Battleships (BB): The pinnacle of surface combat, battleships are expensive and slow but boast the most powerful guns and the thickest armor. They're not all that purposeful other than concentrating firepower as more often others ships are more so deterministic of outcome of battle.
- Battlecruisers (BC): Battlecruisers deliver nearly the firepower of battleships in a faster and less expensive package. Yet it outlives its use upon facing next tier of battleship (1936) by failing to pierce their armor at which point only 10% of that cheap, protected damage package comes through (unlike that of 1940 variant).
- Heavy Cruisers (CA): The smallest and cheapest of capital ships, heavy cruisers out-gun and out-armor screens handily. They often lead small forces. They have the highest efficiency in firepower to cost (vital piercing against other capitals not factored in). This ship outclasses the light cruiser significantly at comparative cost, meanwhile its utility solely lies in working through enemy screens as it's that much more dependable at that than your own screening ships.
- Carriers (CV): The ascendant ruler of the seas, carriers are nearly defenseless on their own but can strike from afar with their complement of aircraft.
Screens scout for the fleet and protect it from submarines and aircraft.
- Light Cruisers (CL): Bigger and more expensive than destroyers, light cruisers are jacks-of-all-trades, being able to engage targets below, on, and above the surface. Being jack of all trades they fail at min-max where they are too easily sunk for amount of good that they should do. In other words upon taking fire their usefulness is likely to end (from ships higher in pecking order), although their evasion stat reaches cap on benefits that it renders (dodging fire).
- Destroyers (DD): Cheap, fast, and flimsy, destroyers specialize at hunting submarines. In a pinch they can close for a torpedo attack. They're the butter of the bread soaking up damage of opposing fleet, through their evasion stat, in combat which makes for best investment, so long as you've invested in making sure that they outlive enemy DDs. Their high torpedo damage will ignore armor, but ultimately isn't an efficient form of damage output due to in-depth naval mechanics.
- Submarines (SS): Small, slow, and stealthy, submarines excel at sneak attacks on unescorted convoys and capital ships. Yet they don't belong in actual combat as they prompt other ships to prematurely flee along with them in vain, besides plethora of other reasons stemming from 1.3 version of game other than that of previously mentioned. On the whole the "cheap, slow, and stealthy" is the only thing going for them putting in that same pattern of pecking order, but against convoys on off chance they offset their cost before they're sunk.
- Convoys: Not shown on-map, convoys carry troops, reinforcements, and land-lease across water. They are defenseless against enemy warships and require an escort in times of war.
These are specific ship classes that are unlocked through research. The statistics of an actual unit may be different, depending on designers and variant.

- "Total cost" is computed as production cost + 0.25 * resource cost, based on the import rate and the cost ratio between military and civilian factories.
- Surface detection and visibility along with sub detection are not precisely accounted for and are simply combined on fleet level as per value present. Single battleship in a fleet of 100 destroyers will almost nullify any detection and visibility stemming from destroyers (V1.3.1).
- Hit points is often secondary factor to organization, evasion, and armor values since screening ships will often just die or quickly flee from capital hit, while capital ships will tank with armor that reduces damage by 90% if not pierced. Aviation damage ignores 2 of these factors more often than not reducing organization of capital ships that they will target more than anything, most likely not leading to a kill in themselves alone (as in bombers alone).
- Evasion has hard upper limit on benefits it renders, light cruisers may surpass it.
- Anti-air attack is definitively useless against carrier based air power that will target capital ships (with screening ships' AA doing nada), fly at least 2 sorties a day, and will always find its target (although being capped at max of 200 total planes per sortie period in 1.3.1 version).
- Sub attack is also not much of a factor since upon investing into airpower+carriers you're would likely be more dependent on carriers to kill revealed submarines rather than expect destroyers to close in (with researched doctrines for escort efficiency), not that subs have much health for it to be truly competitive matter to begin with.
- Shore bombardment has upper limit on benefits it may render which requires merely several battleships.
- Torpedo attack as of beginning of time at up to 1.3.1 version of game isn't a thing, but something that makes destroyers little more of a meat shield in combat. It fires every 4th time, has 20% of being critical doing decent damage then, and may miss altogether (although it ignores armor, so a bunch of destroyers could kill lone heavy ship, but don't count on it as it would be gun-fu).

The operational range of a unit indicates the radius of operation for that particular type of ship on the map, from the closest friendly port (regardless of where the home port for the fleet containing that ship is based). A fleet that combines ships with different operational ranges will have a range that is the average of the individual ships.
