Most Powerful ship is Surveyer

Stardock Forums
I will get complete stats later and repost, but at about midway through my game, the surveyor was being attacked but no damage, infact it destroyed enemy battleship. Eventually my surveyor was so tough that I could take it around destroying fully developed space stations and dreadnaughts. My own dreadnaughts couldn't destroy a spacestation without taking significant damage, but the surveyor...maybe 20 hp of damage of 160 total hps. Now everytime I play a game, I have 2 surveyors running around collecting. Almost like enterprise now...hence the shape?
