Terran Battlecruiser (Starcraft) vs. Klingon Fek'lhr (Starfleet Command III)

They're roughly the same size and shape. Some of you might claim that the most powerful weapon on a Terran Battlecruiser can only fragment a 5-meter diameter asteroid.

I may say that the fastest firing rate on a Fek'lhr is also a shot per 5 seconds, assuming a single disruptor shot at a time. I don't know how many HP a Fek'lhr has, though.
