Warships are a type of building [Sub-type Boat] costing 250 000 gold for the first bought, then increases by 250 000 for each ship owned, up to a maximum of 1 000 000.

To spawn (buy) a Warship, right-click a water source, access the build menu, and buy it. It will then appear at the nearest owned Port and will move to the targeted location.

• Hit Points: 1000 HP
• Cost: Scales with number of warships owned, calculated with this formula:

cost = Math.min(1_000_000, (numWarships + 1) * 250_000)

• Movement: Can move one tile per tick (100ms)
• Territory Bound: No (can move freely in water)

Warships repair through two separate systems, both requiring a friendly Port.

Any warship within 150 tiles of a friendly Port heals 1 HP per tick (100 ms) — 10 HP per second — regardless of the port's level.

A warship that retreats and docks at a Port also draws on that port's repair pool. The pool is 5 HP per tick for each port level, split evenly among the warships docked there, and a port repairs at most as many warships as its level. Combined with passive healing, each docked ship repairs at 1 + (5 × level ÷ docked ships) HP per tick.

So at full capacity every ship repairs at 60 HP/s regardless of port level; a higher-level port mainly lets more ships repair at once, while an under-capacity port concentrates its pool on fewer ships and heals them faster. A warship automatically retreats to repair when it drops below 75% of its (veterancy-adjusted) maximum health.

As of Update 33.0, Warships gain veterancy over their service life, up to a maximum of level 3, shown as gold stripes on the hull (one per level). A more experienced warship is both tougher and hits harder. Only warships gain veterancy.

• Destroying an enemy Warship grants a full veterancy level instantly (and clears any partial progress).
• Destroying Transport Ships or capturing Trade Ships fills a shared progress meter: 10 transport kills or 25 trade captures earn one level. Each transport is worth 1/10 of a level and each capture 1/25, and mixed progress combines.
• Partial progress carries over past a level-up — except a warship kill, which resets it.

Each veterancy level adds +20% maximum health and +20% shell damage. The health boost raises the cap only — the ship does not instantly heal on level-up, it repairs toward the new maximum as normal. Veterancy affects only health and shell damage — not firing rate, range, movement speed, targeting or repair rate.

Warships don't heal when their owning player has no port, and — as of Update 33.0 — can only capture trade ships when their owner has a port in that same body of water.^[1]

Warships will instantly reload after shooting a Transport Ship.^[2]

Warships, when left-clicked, will show a square highlight. If a water source is then left clicked, the selected Warship will move to the clicked location.

Warships will:

• Patrol their assigned area when no targets are present
• Automatically engage enemy ships that enter their targeting range
• Chase and attempt to capture enemy trade ships
• Return to patrol when targets are eliminated

When encountering another Warship or Transport Ship from another country, Warships will proceed to fight. While fighting, Warships will fire bullets at the target until it is destroyed.

• Attack Rate: One shell every 20 ticks (2 seconds)
• Shell Damage: 200–300 per hit (a random roll of 200/225/250/275/300), before veterancy
• Shell Lifetime: 20 ticks (2 seconds)
• Shell Speed: 3 tiles per tick
• Targeting Range: 130 tiles

Warships automatically prioritize targets in the following order:^[3]

1. Transport Ships
2. Enemy Warships
3. Trade Ships

When a warship encounters a trade ship that isn't heading to the warship owners ports, it will rush towards it until it makes contact. The trade ship will then be captured and will be assigned to the nation of the warship.

When chasing a trade ship, warships double their speed and move at 2 tiles per tick (20 tiles per second).

To determine if a trade ship is able to be captured, it must:

1. Not belong to yourself or any of your allies
2. Not be heading towards your own port
3. Not belong to any player your ally is allied with
4. Not be near a coast, in which case it is not capturable.

Note: to see which trade ships are able to be captured, you can hold the "space" bar of your keyboard. Trade ships will appear in green if it belongs to you / heads towards one of your ports, in yellow if it is uncapturable because of an alliance, and red if it is capturable.
