Construction

Introduction

Construction is a feature that enables admirals to build new ships. Building ships consumes 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 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.

According to stats provided on the Kancolle database, there is a correlation between users who built a ship of the same type of ship as the secretary (flagship of fleet 1), so it is recommended to have the same type (or even class) you want as the secretary. 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.

Also 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 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. Small chance of Yayoi.
250	30	200	30	Includes chance of rare destroyers (Shimakaze, Yukikaze, Z3) and submarines (I-168, I-58, I-8). 3.22% for Shimakaze OR Yukikaze. (Shimakaze 2.24%, Yukikaze 0.98%). 3.9% 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	3.85% for Shimakaze OR Yukikaze. 3.36% for submarines. [3]
270	30	330	130	6% for Shimakaze (3.75%) OR Yukikaze (2.25%). 3.8% for submarines. [4]
270	150*	370	50	7.19% for Shimakaze OR Yukikaze. (Shimakaze 2.74%, Yukikaze 4.45%,). 3.73% for submarines. [5] Z3 when using Z1 or I-8 as secretary ship.

• Data from http://kancolle-db.net/ 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.
• 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 .
250	30	200	30	Light cruisers, heavy cruisers, rare destroyers and submarines.

Heavy cruiser

				Remarks
250	30	200	30	Light cruisers, heavy cruisers, rare destroyers and submarines.
270	30	330	130	Slightly higher chance for heavy cruisers.

Battleship

				Remarks
400	100	600	30	BB (32.01%), CA (57.93%), CL (7.38%).
500	30	600	30	BB (32.01%), CA (58.63%), CL (6.87%), also have a VERY SLIM chance to result in Suzuya.

				Remarks

250	130	330	30	5.63% [10] ~250 entries

Large Ship Construction Recipe

Note: Based on Kancolle DB reports.* Results may vary.

					Ship Name	Remarks
Any	Any	Any	Any	Any	Maruyu	5-15% for all recipes.  More common the fewer construction materials and empty dock slots.
1500	1500	2000	1000	1	Nagato-class Mogami-class Agano-class	3.0% Nagato 2.1% Mutsu 3.4% Agano 2.3% Noshiro 1.6% Yahagi 2.3% Mikuma 3.2% Suzuya 3.3% Kumano 14.7% Maruyu (3566 reports)
4000	2000	5000	7000	20	Taihou	6.9% (522 reports)

3600	2000	5300	5200	20	Taihou	6.0% (283 reports)
4000	7000	7000	2000	20	Yamato-class	3.9% Yamato (276 reports) 7.4% Musashi (271 reports) 1.1% Bismarck (276 reports) Bismarck when using Z1, Z3 or I-8 as secretary. [13]
6000	5000	7000	2000	20	Yamato-class	3.3% Yamato (245 reports) 4.3% Musashi (185 reports) 1.2% Bismarck (241 reports) Bismarck when using Z1, Z3 or I-8 as secretary
4000	6000	6000	3000	20	Yamato-class	3.9% Yamato (358 reports) 1.4% Musashi (213 reports) 1.2% Bismarck (347 reports) Bismarck when using Z1, Z3 or I-8 as secretary
4000	6000	6000	2000	20	Yamato-class	2.4% Yamato (4640 reports) 2.1% Musashi (2730 reports) 2.2% Bismarck (4604 reports) Bismarck when using Z1, Z3 or I-8 as secretary
4000	6000	7000	2000	20	Yamato-class	1.4% Yamato (488 reports) 0.7% Musashi (302 reports) 8.6% Bismarck (487 reports) Bismarck when using Z1, Z3 or I-8 as secretary
3600	2000	5300	5200	1/20	Akitsumaru	7.8% (283 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 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.
