It had a lot of disruptor banks, I forgot how much, but was plenty, and had about five forward torp tubes, and two, or three rear disruptor banks, two on starboard or port? She was like a faulty torpedo battlecruiser/heavy dreadnought... The key weaknesses in her was actually the warp nacelles. I forgot which for each action, but if you hit and destroy a specific warp engine on the Ber'taa, she'll either be disabled or will explode to bits... I'm not exactly sure on it, but she's tough if you're a newbie to her, or if Klingons actually fixed the inner-workings so she's doesen't have a weakness as exploitive as the Death Star's.
