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+

Buildable Equipment

Equipment demanding special flagships to be crafted are in Bold.

Unbuildable Equipment

Note that some equipment can appear on more than one list. The lists below do not include buildable equipment. Note that buildable equipment can also be obtained as stock equipment, quests or improvement upgrades. Please refer to the individual equipment pages to find a more detailed list of where to obtain them.

Equipment obtainable as ship girl's stock equipment. Equipment marked in bold are from event-only ships.

Equipment obtainable through Quests. Equipment marked in bold are available from repeatable quests.

Equipment available by upgrading other equipment through Akashi's Improvement Arsenal. Equipment only obtainable via Akashi Improvements are in Bold. Equipment requiring limited ones to be obtained are in Italic

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

A list of common development recipes advised for general crafting, to maximize the rate of craft per resource, condensed down to the most recommended equipment for ease of navigation and use.

NOTE

• These recipes are the minimum, and by extension best, required resource costs.
