Construction

Introduction

Large Ship Construction Menu as shown

Construction is a feature that enables admirals to build new ships. Building ships consumes resources and one development material (or more devmats in the case of large ship construction)   per attempt. Development materials can be earned by completing quests, expeditions, and some sorties.

Construction results are independent of HQ level, and are solely determined by the amount of resources and devmats used. There are also some ships that are currently unbuildable; this list can be found below.

It is sometimes more resource efficient to find your desired ship in sorties as a drop rather than building them, farming ships through sorties also has the added benefit of training your ships.

Large Ship Construction

Large Ship Construction (also abbreviated: LSC) involves the input of a larger quantity of resources (2,000-7,000 for steel, 1,000-7,000 for bauxite, 1,500-7,000 for other resources), along with 1, 20, or 100 development materials  . The cost for instant construction is 10   units.

LSC is unlocked by completing two quests:

  1. Complete Modernization Quest: You will be required to successfully modernize a ship 4 times.
  2. Complete Crafting Quest: You will be required to scrap equipment four times (i.e. perform the scrap action four times, **not** scrap four pieces of equipment)

According to the official Twitter , having empty construction docks very slightly increases the chances of "better" ships appearing, but this has not been formally tested

Large ship construction is used to obtain ships that are otherwise impossible to build in regular construction or difficult to farm, such as Maruyu (who cannot be built in regular construction) or Musashi (who can neither be built nor farmed).

Furthermore, certain ships can only be constructed with designated secretary ships, for instance, constructing Saratoga requires either Kamoi or Iowa (both american-made ships).

  • Kancolle DB reports include all # development materials and secretary ships. This is especially noticeable for BB recipes where the number of attempts with/without Z1/Z3 skew the results towards either Bismarck or Yamato-class significantly. However, since the data sets are still significantly less biased than wikiwiki reports it still gives a better idea of what to expect.
  • It is highly likely that the Z1 unlock quest must be cleared before I-8 or Prinz Eugen can construct German ships. There is only a small amount of evidence for this, but it's generally advisable to simply use Z1, who has been proven.
  • Bismarck and Musashi do not appear with 1 dev mat. Shioi chances are improved with 1 dev mat. Yamato appears with all dev mat inputs. Aiming for Bismarck before Musashi can help save both resources and devmats as Musashi can always appear from a Bismarck attempt, but not necessarily the other way around (if a german ship is not used).
