Note: only asteroid mining is buffed, not planetary mining. So, check how many extractors you can actually build.

Straightforward defense buff.

3 Mil 

Garrison Command 

(TL TE ONLY) 

Spawns 125-500 worth of supply from factories, depending on your tech level. 

Garrison ships can jump to adjacent planets. This does NOT use your supply limit, but you do require a factory on the planet in addition to the planet module. 

You can build heavy cruisers with an upgrade.

This works for defense and offence.

Pay 2.500 credits for 100 supply of pirate ships 

Has a long cooldown, but extremely cost efficient with pirate ships being extra strong.
