Guardians of the Stars
Battle Cruisers are equal in size and tonnage to most Heavy Cruisers, however they are focused around combat almost to the exclusion of anything else. They usually do away with versatility to focus on acting as heavy combatants or task force command ships by striping out research and secondary facilities of most Cruisers. Instead they have fleet command facilities and tactical capability, including a flag bridge for senior officers.
Battle Cruisers tend to have the next best combat capability to Battleships in any fleets, which make them combat monsters in comparison to lesser forces. They are often not as agile as smaller Capital Ships, but are more heavily armored as well. In a fight even a Heavy Cruiser should be no match for a Battle Cruiser in a one on one fight.
Battle Cruisers have gotten very little use. The SAN has traditionally preferred to use Destroyers which are lighter combat focused designs than investing in heavier more expensive Battle Cruisers. Only the proposed Gladiator has managed to make it’s way into a construction yard to be built. The FIC sees them as to expensive when no large scale combat is imminent. Only Republika has built Battle Cruisers in any real numbers.
