The battlecruiser can be destroyed, by firing at the center health area, until it reaches 0. It is easiest to use liberators, disruptor lasers, dark matter lasers, or the icarus heavy AS, which reduce the health rapidly so long as you don't get hit too much.

Terran Carriers and Vossk Battlecruisers cannot be destroyed due to graphical limitations.
