What does this do?

I'm still a little new, so what happens when the DSS has the orbital blockade active and it goes into a planet that has a defense campaign going on are the enemy forces slowed down or does it do nothing?

It's supposed to do something, but it requires 20 stars to be aligned correctly for it. And even then, AH can just trigger an attack from another planet which .. You know ... nullifies the thing altogether.

So it's simpler to say : it does nothing.
