How best to use Null Space weapons?

[Baron Munchausen]

Null-space is a siege weapon, mainly. You use it against huge enemies (like starbases) that you could not damage for a long time if you had to break through the shields and armor first. It works well as an ambush weapon on satelites, too. But the reload time is a problem so yes you need to use it only as a 'secondary' weapon and have a decent complement of regular weapons.
