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 for each attempt. Development materials can be earned by completing quests, expeditions, and some sorties.

The chance of obtaining a rare ship is not affected by headquarters level, but by the amount of resources you put in. New admirals can definitely obtain rare ships, but these are small odds.

The recipes below list the types of ships you may obtain; however, all recipes always have a chance to make more than one type of ship. Keep in mind that the type of ship and the exact ship you will obtain are randomize, so the chances of obtaining the ship you desire may be fairly low. There are also some ships that are currently unbuildable; this list can be found below.

Please refrain from asking "why didn't I get xxx ship with xxx recipe?" Chances are that you simply had bad luck or used the wrong recipe. Take note that sometimes it is easier and more resource efficient to find your desired ship in sorties as a drop rather than building them (i.e. 4 Kongou sisters are quite common drops at world 3-2 node A).

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), either 1, 20, or 100 development materials , and 10 instant construction to immediately finish the construction of a ship. LSC allows the construction of ships like Yamato that cannot be constructed via normal construction, and 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 4 pieces of equipment. Do it one by one as the game will consider discarding multiplies at once, as one time

According to the official Twitter , having more empty construction docks very slightly increases the chances of better ships appearing.

Building Recipes

Disclaimer: These recipes are not guaranteed to give you the ship you want in the number of crafting attempts that you can afford. Percentages listed are sourced from the Japanese databases and are not representative of the real craft-rates.

Destroyer

				Remarks
30	30	30	30	Mainly destroyers and light cruisers, with a small chance of heavy cruisers. No rare destroyers. Small chance of Yayoi, Yuubari.
250	30	200	30	Includes chance of rare destroyers (Shimakaze, Yukikaze, Z1, Z3) and submarines (I-168, I-58, I-8). 1.22% Shimakaze, 1.71% Yukikaze, 2.6% for submarines. [1] Z3 when using Z1 or I-8 as secretary ship. [2] Z1 when using Z3 as secretary ship.

• Recipe percentages don't count Z3 yet.

• 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. Due to low sample size and lack of pictorial evidence other than collected construction data, avoid using her unless you've lost all your German ships after completing the quest.
• 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. Starting with Bismarck then Musashi construction can help save dev mats if you are aiming for all the ships in the long run.
