The Defense Vessel is the Advent's Anti-Strike Craft Frigate. Official Description: Although designed to counter enemy fighters and bombers, the Defense Vessel is also adept at taking on opposing frigates and cruisers. With its pulse laser turrets, the Defense is capable of targeting enemies in almost any direction. Single Defense Vessels are weak, but used in large numbers or as an escort group, they can be a force to be reckoned with, especially when used as escort for capital ships. An Advent crew member feels at ease when she can sense the presence of a fleet of Defense Vessels guarding her flank.
