Development

Introduction

Development requires     resources and   development materials (one dev. mat. is required for each attempt). The rarity and success rate depend on the resource recipe used and your secretary ship's class. Your secretary ship is the lead ship in your first fleet marked #1.

Some equipment is not craftable, see list below.

Often you will fail to produce an item from a recipe, denoted by the penguin-in-a-box screen. In this case, the development material used will be refunded. Development materials can be earned by completing quests, expeditions, and World 2-4.

Please Read This First

  • The recipes presented here do not guarantee that you will get what you want.
  • Percentage of success relates to: HQ Level, Secretary Ship Type, and amount of resources used.
  • Page recipes should come from databases or external sites with at least hundreds of documented attempts. For your own personal lucky recipes and experiences, please use the comments section.

Development theory

According to gathered data, equipment development follows a few patterns. Theoretically, the recipe for any piece of equipment is 10 times its scrap value.

  • Some specific equipment can only be developed when the Secretary Ship is of the correct ship class (not necessarily one that can equip it).
  • When developing equipment, the resource(s) you choose to spend 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 lastly the Bauxite table.
    • For example, Type 0 Observation Seaplane has a theoretical development value of 10 Fuel / 10 Ammo / 20 Bauxite, so in theory it could be created by the 10/10/10/20 recipe. However, Type 0 Observation Seaplane can only be crafted from the Fuel/Steel table, so the recipe that uses the least resource while still capable of developing Type 0 Observation Seaplane is either 20/10/10/20 or 10/10/20/20 (both can be used).

Development recipes

Input material can be adjusted by one digit 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 recipes for other items, please see List of development recipes by item. Yellow Highlighted recipes have large samples sizes and are more likely to have accurate data.
