Well as much as I love star trek... I'm gonna have to go with an Imperial Star Destroyer or a Super Star Destroyer (Dare I be so pretentious?) from star wars. There shields are some of the strongest ever made and are 6x stronger than what should be standard for there size (and there some of the largest capital ships at there time.) They have a small sun for a reactor core so there power supply is also many many times larger than what would be standard for there size. They have more Ion cannons and turbolazers than a military space station. And has numerous fighter and bomber wings in the hanger, not to mention a full invasion force including 5 AT-AT walkers, a legion of stormtroopers, 50 AT-ST's, and 500 dark troopers. Oh and there about 3 miles long. And i'm not even going to attempt to pull up the stats on an SSD.
