Re: How powerful is a Galaxy class starship?
Also I believe the Defiant's top speed was warp 9.0. While the ENT-D max was 9.6 and the E's max was warp 9.9. I seem to recall the Defiant's low speed relative to other ships of that era, due to it having problems maintaining structural integrity while at warp.
I think the episode Sound of Her Voice had the Defiant's top speed at 9.5, which is still lower than the E-D and Voyager. Making her slower than the other hero ships could be a deliberate choice on the writers' part. Maybe something had to go in order for her to be more maneuverable than other ships.
