Construction is accessible from the Arsenal menu and allows building new ship girls. Note that not all ships are available from construction, some being drops from normal maps, and others event exclusive (see below for details).
- For a more comprehensive list of construction recipes and rates, please see PoiDB's construction page.
Constructing a girl costs a selectable amount of the 4 main Resources as well as "development materials" . It will also take a variable amount of time unless instant constructions are used.
- Every player starts off with only 2 construction slots. Up to 2 more slots can be unlocked by using a Dock Opening Key for each.
Construction Types
Two types of ship construction are possible, "Normal Construction" and "Large Ship Construction" (LSC), the former being the most used and cheaper one, and the later being the most expensive with the greatest results.
Normal Construction
"Normal Construction" is the basic construction method. Recipes range from 30-999 fuel , ammo , steel and bauxite and each attempt costs 1 development material . Speeding up construction costs 1 instant construction .
- If applicable, it is often more resource efficient to find a desired ship in sorties as a drop rather than building them.
Construction Theory
In normal construction, there are 4 pools determining the ship being crafted. Each group has exactly 100 unique ships and the available pools remain the same regardless of which Secretary used (excepted for the Z1-class). The selection of a pool is based on the resource input during the construction:
- Pool 1 - 300+ , 400+ , 300+ ,
- Pool 2 - 400+ , 600+ ,
- Pool 3 - 250+ , 200+ ,
- Pool 4 - Do not meet any of the above requirements.
- Note: The check is done from top to bottom, if the requirements of multiple pools are fulfilled, only the topmost one is used.
The constructed ship is selected in the pool by a value called "[math]\displaystyle{ ID }[/math]" which can go from 1 to 100, calculated by substating two random values:
[math]\displaystyle{ ID }[/math] Calculation | ||||
---|---|---|---|---|
In case [math]\displaystyle{ ID }[/math] is 0 or negative, the value will be converted back into a positive value and incremented by 2. | ||||
Which resources that are used to increment value [math]\displaystyle{ Res }[/math] is dependent on the pool that has been selected:

- Pratical Conclusion
- Only 2 resources will have an effect depending on the pool. Changing the two others will have no effect as long as it does not change the pool.
- Of the two resources that have an effect, one has a bigger effect than the other.
- The effect is capped, above a certain threshold increasing the resources further will not have any effect.
- The effect of changing resources will increase the drop of some ships by reducing the drop of others.

Large Ship Construction
"Large Ship Construction" (LSC) allows to build rarer "bigger" ships in exchange for more resources. Recipes range from 1500-7000 fuel and ammo ; 2000-7000 steel and 1000-7000 bauxite . Each attempt also costs either 1, 20, or 100 development materials . Speeding up construction costs 10 instant construction .
- LSC is unlocked by completing quest F10.
- According to the developers, having empty construction docks very slightly increases the chances of obtaining rarer ships [2]. This statement has not been fully tested yet.
- Construction results are solely determined by the amount of resources and devmats used.
- For few ships, an exact Secretary is required in order to be built, see below.
LSC Construction Theory
LSC works similarly to normal construction, there are 4 pools determining the ship being crafted. Each group has exactly 100 unique ships and the available pools remain the same regardless of which Secretary used The selection of a pool is based on the resource input during the construction:
- Pool 1 - > [math]\displaystyle{ 2400+Rand[0;1200] }[/math], > [math]\displaystyle{ 1050+Rand[0;900] }[/math], > [math]\displaystyle{ 2800+Rand[0;1400] }[/math], > [math]\displaystyle{ 2800+Rand[0;2400] }[/math];
- Pool 2 - > [math]\displaystyle{ 2240+Rand[0;1120] }[/math], > [math]\displaystyle{ 2940+Rand[0;2520] }[/math], > [math]\displaystyle{ 4400+Rand[0;2200] }[/math], > [math]\displaystyle{ 1050+Rand[0;900] }[/math], > 20;
- Pool 3 - > [math]\displaystyle{ 1920+Rand[0;960] }[/math], > [math]\displaystyle{ 2240+Rand[0;1920] }[/math], > [math]\displaystyle{ 3040+Rand[0;1520] }[/math], > [math]\displaystyle{ 910+Rand[0;780] }[/math];
- Pool 4 - Do not meet any of the above requirements.
- Note: The check is done from top to bottom, if the requirements of multiple pools are fulfilled, only the topmost one is used.
The constructed ship is selected in the pool by a value called "[math]\displaystyle{ ID }[/math]" which can go from 1 to 100, calculated by subtracting two random values:
[math]\displaystyle{ ID }[/math] Calculation | |||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
In case [math]\displaystyle{ ID }[/math] is 0 or negative, the value will be converted back into a positive value and incremented by 2. | |||||||||||||||||||
In LSC every resource (including ) are used to increment value [math]\displaystyle{ Res }[/math] only the weight depend on the pool:

Special Secretary
Some ships require a specific Secretary (1st fleet flagship) in order to be crafted.
- For any other construction, the Secretary is independent of the crafting result.
