You may use the defense command to add to the starbase's defense. The higher the defense strength of a base, the better able the base is to defend against attacks from enemy ships.
The tech buttons allow you to upgrade your tech levels in four independent areas. These four areas of technology are hull, engine, beam weapons and torpedoes.
The Fix command allows you to repair damaged ships in orbit around this starbase's planet. The command also allows you to load torpedoes and fighters onto ships that are equipped with handle ether one. When you build torpedoes using the build torp command remember to build only the torpedo types that match the launcher types that you are using on your ships, otherwise the torpedoes will remain in storage.
Recycle command will have all the ship's parts taken off the ship and put into storage. The hull is broken up and converted into minerals.
The build fighters/torps command switches to the fighter construction screen. You may have up to 60 fighters in a starbase and you may put fighters on board any ship equipped with fighter bays. The fighters on board a starbase will be used to defend the base and planet against attack.
If a planet comes under attack the fighters on the starbase and the fighters on the planet's surface are launched against the attacking ship. Beam weapons on the planets surface and the beam weapons on the starbase will be fired against the attacking ship. The higher the defense strength of both the planet and the starbase, the greater number and power of the planetary beam weapons.
The build ship command button switches to the build ship screen that allows you to construct starships from components in storage. In the build screen you may select the hull type and engine type and add weapons if possible.
From the build screen you can select sub screens that allow you to construct new starship components such as hulls, engines and weapons. The parts that you build may all be converted back into minerals if you use the "dmp" planetary friendly code.
The Primary base orders command instructs the base to take one of the five automatic actions.
