Empress of Mars-class carrier

The Empress of Mars-class of twenty-four heavy carriers that served both the United Nations Space Authority (UNSA) and the United Nations Space Command (UNSC) from 2156 to 2270. Comprising the eight Empress of Mars carriers, ten Lunar Empress carriers, and six Implacable carriers, the carrier class outsized and outnumbered the previous Solar Princess and Celestial Radiance carriers. Ten members of the class were lost during the Interplanetary War, with two destroyed and eight irreparably damaged. Five carriers were scrapped, and the rest were placed in reserve. 
Following the introduction of commissioned carriers in 2132, the UNSA had completed ten heavy carriers and twelve light carriers, with another six light carriers on order. Despite the successes of the Solar Princess and Solar Seraph heavy carriers, the UNSA came under increasing political pressure to build more powerful carriers, especially from the Unified German Republic and Russian Federation. 
==History==
===Development and construction===
*Solar Princess ('32) and Solar Seraph ('44) heavy carriers 
*Celestial Radiance light carriers ('46)
*UGR political pressure for an "improved Solar Princess" fleet carrier force in 2148, followed by support from the wider European Union by 2150
*Empress of Mars design ('49) favored by UGR and United Republic proponents over additional light carriers, the Solar Warrior proposal ('46), and the 2147 Strike Carrier design. 
===Service===
*Eight Empress of Mars heavy carriers built between 2156 and 2160, with three lost during the war: 
**Empress of Europa, lost in the Belt in 2166; Empress of Callisto, lost in the Belt in 2167; and Empress of Mars, lost at Europa in 2167 during the Europa Whirlwind. 
*Ten Lunar Empress heavy carriers built between 2161 and 2163, with five lost during the war: 
**Empress of Ceres, destroyed in August 2165 during the Jovian Action; Empress of Tethys, destroyed in the Belt in 2166; Empress of Vesta, lost at Europa in 2167 during the Europa Whirlwind; Empress of Pallas, lost in the Belt in 2168; and Empress of Juno, lost in 2169 during the Braam-Saburov Offensive. 
*Six Implacable-class heavy carriers built in 2164 and 2165, with two lost during the war: 
**Formidable, lost at Europa in 2166 during the Europa Whirlwind and Victorious, crippled in January 2170 during the Trojan Offensive. 
==Design==
*Eight Empress of Mars heavy carriers
===Lunar Empress-class===
*10 additional heavy carriers: Lunar Empress in 2161, Terran Empress, Empress of Ceres, Empress of Vesta, Empress of Juno, Empress of Pallas, and Empress of Titan in 2162, and Empress of Rhea, Empress of Tethys, and Empress of Iapetus in 2163. 
*Lunar Empress carriers had better speed and significantly improved point defense systems, though the Empress of Mars carriers would receive a similar upgrade in 2162. 
*Adjustments to the hull and internal layout resulted in some small but dangerous vulnerabilities that went undetected until the loss of the Empress of Pallas in 2168. 
===Implacable-class===
*Originally ordered as six additional Lunar Empress carriers, the Implacable heavy carriers were instead built to a modified design
*Implacable carriers sacrificed the speed of the previous Lunar Empress-class in exchange for heavier armor, more missile pods, and significantly heavier point defenses
*Built by SVR Shipyards: Implacable, Formidable, and Victorious in 2164 and Admirable, Venerable, and Triumphant in 2165.
