Fleet Ship Module
The number of Fleet Ship Modules required to purchase a Fleet Ship will vary based on the ship, other ship unlocks on your account, and other factors. For example, if your character already owns the tier 5 C-Store version of a ship, then the respective "Fleet Retrofit" will not cost 20,000 and four modules, but only 20,000 and one module.
Fleet Ship Modules are single-use items that are tradable or sellable through the exchange. Once used or resold, Fleet Ship Modules cannot be reclaimed.
