The Essex Class Heavy Escort Carrier is Joint Design between the IMCF and the CMSF for the Confederated Martian Security Forces to Escort Larger Carriers and Battleships like the CSS Virginia, despite being in the Prototype Stage: the Essex itself was more than a Match to Viragonian Warships due to it's Weapons and Massive Fighter Complement as shown after the Essex was Attacked as it Underwent it's trials by the Time the CIS Virginia Arrived to come to the Essex's Aid.
