After the Battle of Earth, the Lexington-class became the new backbone of the Terran Defense Fleet. More than a match for their Kilrathi counterparts, these carriers can take critical hits in multiple launch bays and still maintain flight operations. They are traditional carriers with minimal weapons and must rely on escorting warships for support, but they do possess a full compliment of fighters and the heaviest shielding and armor this side of a starbase. The majority of these vessels have been withheld from the front to defend Earth and the Inner Colonies.
