@BlackRabbit and its powered by an artificial black hole!
well of course! what else would you use to power that monstrosity? an antimatter reactor just wouldn't do, i imagine the power to cloak something that large would be equivalent to a few large cities?
and that's not even getting into the insane amount of power needed to generate a warp bubble for something that massive!
