Development

Introduction
Crafting 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.

 * 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 (see kancolle-db.net for more info).


 * 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. However, some specific equipment can only be built when the Secretary Ship can equip that equipment. Also, the resource you use the most of in a given attempt will increase the likelihood of related equipment types types: Ammo creates Weapons, Steel creates Engines, Bauxite creates Aircraft, Radar or Sonar.
