The Evil Empire is very good at mass producing fighters. Each Starbase (including Mining Stations) of the Evil Empire has the ability to create several fighters each turn from the minerals (3 KT Tritanium and 2 KT Molybdenum).
Similar advantages are available for 1, 2, 3 or 4 fighters. They do not depend on each other, and may be combined in any way (including the 5 free starbase fighters base advantage) to build as many as 15 free fighters each turn.
This advantage is disabled by default, and can be researched with Campaign Resources. No special Mission or Friendly Code is required to trigger this advantage. If the minerals are available on the planet, and there is room on the starbase, the fighter will be built.
This advantage is worth 10 advantage points and is only available to The Evil Empire.
The research cost for this advantage is 1000 GigaCredits.
