Development
Development is accessible from the Arsenal menu and allows equipment building. Note that only some equipment is available through development. The majority of equipment are ship girl default equipment, results of Improvement upgrades, event-only or ranking-only. See below for details.
For a more comprehensive list of construction recipes and rates, please see PoiDB's or TsunDB's development pages. The latter sorts by equipment, the former sorts by flagship type and primary resource.
Overview
Recipes range from 10-300 Fuel 
, Ammo 
, Steel 
and Bauxite 
. Each successful development costs 1 development material 
. The rarity of the equipment obtained depends on the recipe used. The type of equipment obtained depends on the recipe used and the ship girl that is used as the secretary. It is possible to craft three equipment at once by using the Concentrated Development (集中開発) toggle.
Development Notes
- Based on data, development recipes appear to be about 10 times the equipment's scrap value.
- Some secretary type may be needed to craft some specific equipment.
- The secretary need not necessarily be capable of equipping the equipment.
- When developing equipment, the resource(s) spent the most determines which crafting table the game pulls the result from. If there's a tie, Fuel/Steel (same table) has the highest priority, followed by the Ammo table, and then the Bauxite table.
- For example, Type 0 Observation Seaplane has a scrap value of 1 Fuel, 1 Ammo, and 2 Bauxite, so in theory, it could be created by the 10/10/10/20 recipe. However, the Type 0 Obs is on the Fuel/Steel table, the minimum recipe for the development of such planes is, therefore, either 20/10/10/20 or 10/10/20/20.
- HQ level factors into development. A HQ level of 10 times the rarity of the equipment is needed to craft it.
| Rarity | Rarity | Requires HQ |
|---|---|---|
| レア | Rare | 10+ |
| ホロ | Holo | 20+ |
| Sホロ | S Holo | 30+ |
| SSホロ | SS Holo | 40+ |

Equipment currently unobtainable in-game. They were event rewards, ranking rewards or limited-time quest rewards. They may return as stock equipment, improvement upgrades, event rewards, or quest rewards in the future. Equipment obtainable via Akashi Improvements from "unobtainable equipment" are in Bold. This list does not include equipment from event-only ships.
Note that the equipment IDs 265, 321, 448, & 462 were never added to the game.
- The Reppuu Kai Ni (CarDiv 1/Skilled) (ID 337) was added to game files, but never given away.
Common Development recipes
Input material can be adjusted by one unit at the top and bottom of the frame that says the number in the "▼" button "▲".
NOTE: These recipes are the minimum required resource costs, condensed down to the most recommended equipment for ease of navigation and use. If you would like to see data for other equipment, please see Development/Equipment_Rates.
