Atlas

The Atlas is an NPC ship that serves as its team's AI carrier. At 4 kilometers in length and with a dry mass of over 30 million tons, it is one of the largest ship classes ever constructed, and the time and resources necessary to complete even one of these behemoths means only 10 have been made. Because of this value, an Atlas is generally only fielded for major operations or as a show of force; lesser engagements can be handled by much smaller escort carriers.
