Introduction

Construction is a feature that enables admirals to build new ships. Building ships consume resources and one development material for each attempt (the two nail-looking things at top right hand corner). Development materials can be found by completing quests, expeditions, and some sorties.

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

According to stats provided on the Kancolle database, there is a correlation between users who built a ship as the same type of ship as the flagship, so it is recommended to have the type (or even class) you want as the flagship. 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 here.

Also please refrain from asking "why didn't I got xxx ship with xxx recipe?" Chances are that you didn't read this section, used the wrong recipe, or simply had bad luck. 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 (2000-7000 for steel, 1500-7000 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 of construction allows much rarer ships such as the Yamato to be constructed. 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.
250 30 200 30

Includes chance of rare destroyers (Shimakaze, Yukikaze, Z3) and submarines (I-168, I-58I-8).

3.22% for Shimakaze OR Yukikaze. (Shimakaze 2.24%, Yukikaze 0.98%). 3.9% for submarines. [1]

250 130* 200 30 3.85% for Shimakaze OR Yukikaze. 3.36% for submarines. [2]
270 30 330 130 6% for Shimakaze (3.75%) OR Yukikaze (2.25%). 3.8% for submarines. [3]
270 150* 370 50 7.19% for Shimakaze OR Yukikaze. (Shimakaze 2.74%, Yukikaze 4.45%,). 3.73% for submarines. [4]
  • Data from http://kancolle-db.tk/ suggests that increasing fuel, steel, and ammo all increase the chance of receiving a rare DD. However, it appears that values higher than 300 fuel and 400 steel begin to generate more CV/CVLs and fewer rare DDs.  Further increasing bauxite does not appear to have a significant impact on the chance of receiving a rare DD or SS and is more likely to result in CV/CVL.
  • Recipe percentages don't count Z3 yet.
