"One Super MAC and three Baby MACs. That's the kind of firepower that defines the word "backbone.""
The Southern Cross-class large fleet assault carrier (known more commonly as a fleet carrier and somewhat incorrectly as a supercarrier) was a massive capital-grade warship of the United Nations Space CommandNavy. The Southern Cross-class was, at the time of its debut and for years to come, unarguably the most powerful Human-built warship in existence.
Ships of the class would not be truly tested until JAFCOM's intervention of the Second Great War in the early 2590s . Throughout the war, Southern Cross-class vessels led ODI offensive campaigns comprising as many as two hundred vessels. Due to a limited quantity and demand, though, only forty of these gargantuan carriers were put into service over a thirty five year span (as opposed to the Reach-class battleships, of which as many as two hundred vessels were commissioned).
