that works fine when they're fending off an entire fleet of ships. But if there was only one cruiser, it would have to be far feistier to prove a challenge.
Actually The Defiant was on shoting Jem'Hadar Bugships in the episode where they were fighting them in that gas giant.
Yeah that bugged me as well. I just saw that episode for the first time last week and I was like... "Ok this totally contradicts what we've been told"
and it can't be because of the gas giant radiation because the defiant's shields seemed unaffected
