[Baron Munchausen]

The Null Space weapon is great as either an 'ambush' weapon -- put it on satellites guarding a warp point for example -- or as a siege weapon where you have to go in and attack some incredibly huge and well defended base/planet. You can start doing damage immediately instead of having to break through all the shields/armor. But in standard combat where you have to close with another moving ship to fire and then get away the slow fire rate can be a problem. Note: The PPB penetrates planetary shields. They are 'normal' shields. So, this can be a very useful planet attack weapon, too.
