Defending Planets

[Taz-in-Space]

I use satellites in the later parts of a game. As stated, mines become ineffective due to increased sweeping. Satellites however are harder to bypass especially if properly used.
And satellites are reusable.
Especially effective are satellites placed at a recieving warppoint. (one that ships jump to.)
And satellites can be built on ANY planet. As long as I can afford the minerals, I use any tiny/small or domed planet to churn out satellites and fighters. Put them in orbit for the future - once built they cost NOTHING. Any fleet that hits one of my back systems will encounter many satellites and massive fighter swarms!
