OpenFront Warship Fleet Decisions: When to Buy, How Many, and Where to Patrol

Direct answer: what is the Warship spend decision

A Warship is a sea-control unit you build at a Port. It spawns from your nearest Port, anchors on the first water tile you click, patrols that tile, captures enemy Trade Ships, and destroys enemy Transport ships and Warships. It carries 1,000 base health and fires 250-damage shells, and it prioritizes Transport ships first. When its health reaches 75 percent of its maximum it automatically retreats to repair, it passively heals while within 150 tiles of one of your active Ports, and it repairs faster when docked within 5 tiles of a Port, which adds a heal pool of 5 per Port level per tick. A Warship can also gain up to 3 levels of veterancy, each adding 20 percent more base health and 20 percent more shell damage. All of these numbers are the v0.34.11 rules, so treat them as the baseline for the decision framework below rather than for an older patch.

The decision this guide answers is the spend-and-placement question, not the per-ship experience question. In one sentence: a Warship is a gold-denial tool, so you should build one only when you have a Port, a lane that actually moves gold, and a specific threat to answer, and every ship you field must keep a friendly Port within retreat-and-heal range. Fleet size follows the cost ladder, where the first ship costs 250,000 and each later ship costs more until a hard 1,000,000 cap, so a second ship at 500,000 is a deliberate commitment and a capped fourth ship is reserved for protecting one named high-value target. The framework in the rest of this guide is a chain: confirm the gates, place the ship on the gold lane, size the fleet to the cost ladder, position each additional hull, decide when a late capped ship pays, and manage the whole fleet with the box-select and F and R controls so the placements you make actually stick.

This guide is one of two naval pages on the site, and the split matters for what to read next. The page that handles the individual ship’s experience bar, repair threshold, and retreat timing is the warship veterancy guide; that one answers “what do I do with the ship I already have.” This page answers the question a few levels up: whether to spend the gold at all, how many hulls to field, where the fleet should sit, and how to keep the fleet from drifting off the lanes it is supposed to hold. The page that handles five-minute Team-mode fleet roles is the team naval control guide, which is about coordinating a group of players’ ships rather than the single-player spend decision this page is built around. Keeping those three pages separate means each one can give a clean answer without repeating the others, so use this page when your question is about the money and the placement, and switch to the other two when your question is about a specific ship’s health bar or about a coordinated team push.

When to build your first Warship

The first Warship costs 250,000 gold and takes 50 units of time to build. That is a real amount of gold and a real delay, so the question is not “is there water on the map” but “does the gold get spent where it pays back the threat it answers.” A first ship is only justified when three gates pass at the same time, and the habit is to check all three before you click, not to build first and rationalize the placement after. The three gates are the port gate, the traffic gate, and the threat gate, and failing any one of them means the gold is better spent on something else this turn.

The first gate is the port gate. You need a built Port on water. A Warship spawns from your nearest Port and patrols the tile you first click, so without a Port there is nothing to build from and the build menu will not offer a usable Warship. If you do not have a Port yet, the 250,000 you would spend on a ship is better spent finishing the Port that unlocks the ship, because the Port also opens your Trade Ships and your own gold flow, which means the Port is worth more in the early game than the ship it eventually enables.

The second gate is the traffic gate. There must be water that actually carries value, which means enemy Trade Ships or your own and their Transport routes run through it. A Warship sitting on empty water captures nothing and denies nothing, so it is a 250,000-gold decoration that looks active on the map but is not doing any of the work that justifies its cost. Check the lane before you click, and if the only water you can see is a quiet bay with no route through it, the traffic gate is not met even if the other two are.

The third gate is the threat gate. There must be a reason to answer, such as an opponent raiding your trade, an opponent about to land, or a contested water gap you need to close to protect a landing. If no one is contesting the water, a Warship has no job and the gold should go to a City, a Defense Post, or a second Port instead. The cost of failing these gates is easy to see, and the most common early mistake is building a first Warship the moment you can see water on the map, before the traffic gate and the threat gate are met, and then watching the ship idle on an empty bay while the 250,000 gold that could have funded a second City sits in a hull that does nothing. The decision should come from the threat and the lane, not from the fact that the map happens to have an ocean. If you are not yet sure which structure to spend on, the when to build each structure guide walks through the building ladder and where a Port fits in it, which is the right reference to settle the port gate before you commit the ship.

Gate	Pass condition	What fails it
Port	A built Port on water exists	No Port, or the Port is unfinished
Traffic	A lane carries real Trade or Transport value	Empty water with no route through it
Threat	A named opponent action to answer	No one contesting the water

How to place the first Warship: follow the gold

Placement is the second-highest-leverage decision after the build decision, because a well-placed ship on a busy lane outperforms a worse-positioned fleet of the same size. The rule is to place the ship on the lane that moves gold, not on the nearest water. A ship on your own coast that no one uses is doing nothing, while a ship pushed out onto the enemy’s main Trade or Transport route is capturing and denying the exact gold that would otherwise flow to them. The mental model is to ignore the water that is close to you and instead find the water that the money actually moves through, then anchor the ship there.

You need two ranges to reason about placement. The patrol range is 100 tiles, which is how far the ship wanders around its anchor while it is idle. The targeting range is 130 tiles, which is how far it can actually open fire and acquire a target. The first water tile you click becomes the patrol anchor, so that single click decides the zone the ship will hold. A good anchor sits on or just beside the lane so that the 130-tile targeting reach covers the lane the ships actually travel. If the lane runs in a line, anchor the ship beside the lane rather than far behind your own coast, so the ship meets the traffic before it reaches the port it is feeding and can deny it on approach.

The retreat geometry is what most players miss, and it is the part that turns a good placement into a bad one. A Warship passively heals while within 150 tiles of one of your active Ports, and the 75 percent auto-retreat only sends the ship back to a Port that it can actually reach and heal at. A ship placed 300 tiles from your only Port will take a fight, drop to 75 percent, auto-retreat, and then sail a long way to a Port while it cannot re-engage, which makes it effectively dead for the duration of that trip even though it is still on the map. So the placement rule has a second half: the ship must sit on a valuable lane AND within a practical retreat distance of a friendly Port, and when both are required the lane you hold is the one that is close enough to a Port to survive the fight.

When the lane you want to hold is too far from any Port, the fix is to build a forward Port that brings the heal range forward, not to force a ship into a lane it cannot survive in. A forward Port is a Port pushed out toward the contested water so that the 150-tile heal range covers the lane, and it is the same investment logic as a second Port except it is placed for naval coverage instead of extra trade. That forward-Port decision is the same logic the island defense guide uses when it screens a coast that needs a Port to hold, so if your map is island-heavy the two guides are reading the same geometry from different angles. The practical check before every first ship is: is this lane busy, is it within 150 tiles of a Port I can build, and is the Port I would build there worth the gold on its own. If all three are yes, place the ship and build the Port. If the lane is busy but no Port fits, hold off the ship until the Port does, because a ship with nowhere to heal is a ship that is slowly being spent.

Fleet size: the cost ladder and when a second ship pays

The cost of a Warship rises with every ship you already own. The rule is the minimum of 1,000,000 and the number of existing Warships plus one, times 250,000. So the first ship is 250,000, the second is 500,000, the third is 750,000, and the fourth and every ship after that is capped at 1,000,000. That ladder is the single most important number in this guide, because it means a second Warship is twice the cost of the first and a fourth Warship is four times the cost of the first, and the marginal cost keeps climbing until it hits the cap. The ladder exists to make a fleet a real decision rather than a free one, so the question for every ship after the first is whether the lane it covers is worth the jump in price.

Ship number	Gold cost	What it buys you
1st	250,000	First lane control, usually a single main trade or transport lane
2nd	500,000	A second independent lane, or a flank the first ship cannot cover
3rd	750,000	A third lane, or a dedicated escort for a named landing
4th and later	1,000,000	Protects one specific high-value target, not general insurance

A second ship at 500,000 is only worth it when one of two things is true. The first is that your single ship cannot cover your lanes, which means you have a second lane that moves real gold and the first ship cannot reach both lanes at the same time. The second is that you have a second Port or a second coast you need to protect, so the first ship is tied to one area and a second ship covers the other. If neither is true, the 500,000 is better spent on a Port that opens more trade or on a City that grows your population, and the single well-placed ship continues to do its job. The cost of a second ship is high enough that the default answer should be “no” unless one of those two conditions is met.

The common failure is buying a second Warship because the first one felt exposed, when the real problem was that the first ship was placed wrong or too far from a Port. A second ship on the same lane does not fix a placement problem, it just spends another 500,000 on a lane that was already covered. Check the placement and the Port range before you add a second hull, and if the first ship is the one that is out of position, move it instead of buying. A third ship at 750,000 follows the same test with a higher bar, and the pattern that keeps the fleet honest is to treat every ship after the first as an exception you justify, not a default you assume. If you are trying to spread the same lane across two ships because it felt under-defended, the lane is probably the thing to fix, not the fleet, so look at the anchor and the Port before you spend the 500,000.

Positioning the second and third Warships

Each Warship is anchored by the first water tile you click after building it, and it patrols that tile with a 100-tile patrol range while it can reach out to 130 tiles to fire. That means the second and third ships are not just “more of the same”; each one is a separate placement decision with its own lane and its own retreat distance to a friendly Port, and the cost of getting the split wrong is that you pay 750,000 for one lane instead of two. The whole point of the second and third ships is to cover more lanes, so the placement of each one is a question about which lane it is holding and whether that lane is a lane the first ship was not already covering.

The second ship should take the lane the first ship cannot cover, and it should be anchored on that lane rather than clustered next to the first ship. If both ships sit in the same 100-tile zone, you have spent 750,000 on one lane and you have no coverage of the second, which is the single most expensive mistake in this guide. Spread the fleet across the lanes that actually move gold, and make sure each ship is within a practical retreat range of at least one friendly Port so the 75 percent auto-retreat can bring it home to heal. The test for the second ship is the same as the cost-ladder test: does it cover a lane the first ship does not, and is that lane busy enough to be worth the 500,000. If the answer to either is no, the second ship is not ready.

The third ship at 750,000 is a large commitment and should be reserved for a specific job rather than a general “more ships” instinct. The jobs that justify it are a third independent lane, a dedicated escort for a landing you are about to run, or protection of a second Port that has become a real economic target. If none of those jobs exist, a third ship is usually a sign that your problem is not lack of hulls but a map you are trying to hold with too many separate fronts. In that case the better move is often to commit to fewer fronts and concentrate the two ships you already have, rather than spread three ships thin across lanes that none of them fully controls. A third ship that has to cover a lane it can only half-reach is worse than two ships that each fully control their own lane, because the half-covered lane leaks exactly the gold the fleet was supposed to stop.

The placement habit that ties this together is to re-check the lane, not the ship. When the enemy changes their Trade route or you add a new Port, the lane moves, and the ship that was correctly placed last turn is now sitting on an empty bay. You move the anchor to the new lane, and only when the lane genuinely splits do you consider the gold for a new hull. This is where the F and R controls from the next section come in, because re-anchoring the fleet as the lanes move is a routine action you do many times a match, and doing it by clicking each ship one at a time is exactly the kind of attention drain that makes players forget to move the fleet at all. The habit to build is to re-check the lanes every few minutes, and when a lane has moved, use the fleet controls to re-anchor the ship that was on it before you ever think about buying another one.

Late-game Warships and the 1,000,000 cap

Once you reach the fourth Warship the cost stops scaling and every additional ship is a flat 1,000,000. That flat cap changes the decision, because the marginal cost of another hull is now the largest single build you can make and it does not get cheaper, so a late capped ship is the worst value in the game unless it is answering a target you can name. In the late game a Warship is also less about capturing Trade and more about denying a specific thing, because most of the map’s Trade is already contested and the value that remains is concentrated on a small number of high-value targets. The shift from “capture the trade” to “deny the target” is the shift that decides whether a capped ship is worth the million.

The situations that justify a capped late-game Warship are specific. The first is a landing, where you are moving troops across water and an enemy ship or Transport on that lane can undo the whole operation. The second is a nuke-prep or a late economic push, where one Transport strike can cost you the gold you need and the lane to your Port is the thing to deny. The third is the last Trade lane that still moves meaningful gold, where capturing or denying it is worth more than the 1,000,000 it costs to field the ship. In every other case a flat 1,000,000 ship is the worst gold you can spend, because you can buy a City, a SAM, or a Missile Silo for less and still be more relevant to the game you are actually playing. The rule is to only buy a capped Warship when it protects or denies a target you can name, and if you cannot name the target you do not buy the ship.

The mode and the map change the bar for that capped ship. On maps with a single water gap that most traffic must cross, the late-game denial value is high because the one lane you are protecting carries most of what is left, and a capped ship there is often worth it. On maps with multiple independent water routes, the late-game denial value is lower because there is no single lane that carries most of the value, and a capped ship is rarely the best million-gold spend. In modes that reward a decisive late-game push, the capped Warship is more likely to be worth it, because the high-value target you are protecting is a landing or a nuke-prep and the denial value is real. In modes that end on a territory threshold before the late economy fully develops, the late-game Warship is less likely to pay for itself, because the game can end before a million-gold ship reclaims its cost. The timing of when the auto-retreat and repair rules still apply, and whether a veteran ship should hold or run, is covered in the warship veterancy guide, which handles the per-ship retreat math in detail, so use this page to decide whether to buy the capped ship and that page to decide what to do with it once it is on the water.

Managing the fleet: box-select and the F and R keys

A single Warship you manage by clicking it is one thing; a fleet of three or four ships you have to click one at a time is a constant tax on your attention. The v0.34 series added controls specifically to solve this, so fleet management should not require you to re-click every hull you want to move. The three controls are F, R, and box-select, and they are all customizable, which means if you have changed your keybinds the same workflow applies with your own keys, but the default bindings are what this section describes.

F selects all of your Warships at once, so instead of clicking four ships you press F and the whole fleet is selected. R then re-issues the patrol order for the selected ships, which lets you reposition the whole fleet with one command instead of anchoring each ship separately. Box-select, drawing a selection box over a group of ships, lets you select a subset of the fleet, which is how you move some ships and leave others in place. Pressing F again or Escape cancels a Warship selection when you have over-selected. The reason the v0.34 series added these is that a fleet is a thing you re-anchor many times a match as the lanes move, and clicking each ship individually made the re-anchoring expensive enough that players stopped doing it, so the ships drifted off the lanes they were supposed to hold.

The workflow is: use F to select the whole fleet and R to shift the whole fleet when the lane or the map has changed; use box-select when only part of the fleet needs to move and the rest should hold; and use F or Escape to drop a selection you do not want. The decision layer is knowing when to move the whole fleet versus a subset. You move the whole fleet when the enemy has changed their main lane and every ship is now off it, which is the situation where one R fixes everything. You move a subset when you are reassigning one ship to a new job, such as pulling one ship to escort a landing while the rest keep holding the trade lanes, which is the situation where box-select lets you move exactly the one ship that needs to move. Managing the fleet this way keeps you from the failure mode of a fleet that is technically present on the map but anchored on stale lanes from a turn when the map looked different.

The habit that makes this work is to re-anchor with the lanes, not with a clock. You do not re-anchor the fleet on a timer; you re-anchor it when the lane it is holding has moved or when you are reassigning a ship to a job. The signal to re-anchor is the same signal from the placement sections above: a lane that used to move gold now does not, or a new lane has appeared that the fleet does not cover. When that signal fires, use F and R for the whole fleet or box-select for the part that needs to move, and the fleet stays on the lanes that matter. This is the difference between a fleet that is a set of anchors you placed once and a fleet that tracks the gold, and it is the single biggest reason a well-positioned three-ship fleet beats a worse-positioned four-ship fleet.

Failure modes and countermeasures

Most Warship losses are not losses to a stronger enemy fleet. They are losses to placement, timing, or the cost ladder, which is the same lesson as the placement and cost sections above but framed as what goes wrong and how to fix it. The four that show up most often in the community and in matches are the overextended lone ship, the idle ship on the wrong lane, the late fourth ship bought out of fear, and the unvetened replacement. Each one has a clear countermeasure, and the countermeasure is usually to not spend the gold rather than to spend it better.

The overextended lone ship is a single ship placed far from any friendly Port. It fights, it drops to 75 percent, it auto-retreats, and then it spends a long trip sailing back while it cannot re-engage, so it is effectively dead for the whole trip. The counter is the retreat geometry rule, anchor the ship within a practical 150-tile heal range of a Port, or build a forward Port to bring the heal range to the lane you need to hold. The overextended ship is the most expensive version of this failure because it usually has already been placed and the gold is already spent, so the fix is to notice it is out of range and build the Port, not to keep expecting it to hold a lane it cannot heal on.

The idle ship on the wrong lane is a ship that was correctly placed when the map looked different and has not been moved since the lane changed. It shows as active and healthy but captures and denies nothing. The counter is the periodic re-check, use F to select the fleet and R to re-anchor it to the current lane, and move a subset with box-select when only part of the fleet is off the lane. The idle ship is the failure that the F and R controls exist to prevent, so if you are seeing idle ships the likely cause is that you are not re-anchoring the fleet as the lanes move, and the fix is to make the re-anchor a habit rather than a one-time action.

The late fourth ship bought out of fear is a flat 1,000,000 ship with no named target. The counter is the naming rule, do not buy a capped ship unless it protects or denies a target you can name. The unvetened replacement is spending gold on a fresh ship when you already have a level-2 or level-3 veteran that out-damages and out-heals the replacement, so the new hull is strictly worse until it catches up. The counter is to check the warship veterancy guide before replacing a veteran, because a veteran’s higher health and damage usually mean the cheaper move is to keep it and repair it, not to field a weaker replacement.

Failure mode	Symptom	Countermeasure
Overextended lone ship	Long retreat, dead for the trip	Anchor within 150-tile heal range, or build a forward Port
Idle ship on wrong lane	Active, healthy, doing nothing	F to select, R to re-anchor to the current lane
Fear-bought fourth ship	Flat 1,000,000 with no target	Do not buy unless it protects or denies a named target
Unvetened replacement	New hull weaker than the veteran you replace	Keep and repair the veteran; check the veterancy guide first

The unifying rule is to never buy a Warship without knowing the lane, the Port, and the threat it answers, and to never keep one on a lane that no longer moves gold. If a Warship feels like it is doing nothing, the answer is almost always the placement or the Port, not the fleet size, and the four failures above are the four shapes that mistake takes. The team naval control guide covers the team-level version of these failures, where a coordinated fleet has to agree on which lane each ship holds, but the single-player version is the one this page is built to fix, and the four rows above are the checklist to run before you spend the gold on the next hull.
