The Aniran equivalent to the Tellusain battlecruiser is called a Fleet Assualt Ship. However, these ships are a lot larger and pack a bigger punch. The analyst has observed three major advantages the FAS has over their Tellusian counterpart ships.
Firstly, it is the ultimate hunter-killer, based on the size and power output of its battery of super-heavy, anti-ship mass driver cannons designed to destroy enemy capital ships.
A second advantage this class of ship has is its ability to carry an entire squadron of interceptors, which is near equivalent to the Mars-class attack carrier, as well as a heavy complement of drop troops.
The third major advantage of the FAS, is the enhanced defensive package and added armor that allows it to stay in combat against other capital ships.
The very nature of these ships has kept Terran military analysts spinning their heads on how to effectively combat them.
