Crafting equipment requires between 10 & 300 of each main resources fuel {{Fuel}}, ammo {{Ammo}}, steel {{Steel}} and bauxite {{Bauxite}}, as well as 1 "development material" {{DM}}.
*Input resources can be adjusted by one unit at the top and bottom of the frame that says the number in the "▼" button "▲", or in 10 by 10 or 100 by 100 increments.
*It is possible to craft '''three equipment at once''' by using the '''Concentrated Development (集中開発)''' toggle.
For a given resource input, the development has a chance of failure (penguin) and success, with the DevMat {{DM}} only being consumed for successful developments.
The equipment crafted depends on:
*The recipe used, with several ranges of resources input affecting more or less the crafting pool,
*The {{Secretary}} when doing the crafting, directly affecting the pool of equipment that can be crafted and the related rates.
** Some specific equipment can be crafted exclusively or at a higher rate with some specific ships or ship classes as secretary.
**'' Secretaries may craft some equipment they cannot equip, such as land based planes.
*The "rarity" of said equipment, relative to the personal [[HQ]]
