Construction

Introduction

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 found by completing quests, expeditions, and some sorties.

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

The recipes below list the type of ships you may obtain, but 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 totally random, so the chances of obtaining the ship you desire may be fairly low. There are also some ships that are currently unbuildable, the 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 is a quite common drop at 3-2 node A).

Large Ship Construction

Large Ship Construction 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), in addition to a selection of either 1, 20 or 100 development materials and will require 10 Instant Construction to immediately finish it. This method allows the construction of ships like Yamato that cannot be constructed via normal construction. It 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 ON SOME RECIPES ARE SOURCED FROM wikiwiki.jp/kancolle AND ARE NOT REPRESENTATIVE OF ACTUAL IN-GAME CHANCES.

PLEASE ADD NEW RECIPES YOU BELIEVE SHOULD BE REVIEWED FOR ADDITION INTO THE SPECIAL TABLE AT THE BOTTOM OF THIS SECTION.

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.
250	30	200	30	Includes chance of rare destroyers (Shimakaze, Yukikaze, 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.
250	130*	200	30	1.47% Shimakaze, 1.24% Yukikaze. 2.87% for submarines. [3]

• Recipe percentages don't count Z3 yet.
• It is highly likely that the Z1 unlock quest must be cleared before I-8 can construct Z3. 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.

Light cruiser

				Remarks
30	30	30	30	Mainly destroyers and light cruisers, with a small chance of heavy cruisers. No rare destroyers. A small chance of Yuubari (1%).

4000	6000	6000	3000	20	Yamato-class Yamato Focus	3.5% Yamato (26 results) 1.5% Musashi (85 results) 1.1% Bismarck (95 results) (748 reports) Bismarck when using Z1, Z3, I-8 or Prinz Eugen as secretary. [11]
4000	7000	7000	2000	20	Yamato-class Musashi Focus	2.7% Yamato (31 results) 5.3% Musashi (62 results) 0.6% Bismarck (7 results) (1167 reports) Bismarck when using Z1, Z3, I-8 or Prinz Eugen as secretary
4000	6000	7000	2000	20	Yamato-class Bismark Focus	1.4% Yamato (21 results) 1.2% Musashi (18 results) 6.7% Bismarck (101 results) (1500 reports) Bismarck when using Z1, Z3, I-8 or Prinz Eugen as secretary
4000	6000	6000	2000	20	Yamato-class Most Reported	2.2% Yamato (179 results) 1.3% Musashi (104 results) 1.9% Bismarck (152 results) (8074 reports) Bismarck when using Z1, Z3, I-8 or Prinz Eugen as secretary
3600	2000	5300	5200	1	Akitsumaru	6.6% (562 reports)

• Reports typically 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.

LSC reports

The reports from the japanese wiki collected and visualized.

Note: It is far from accurate because success is more often posted than failures, avoid the ones with low sample size.
