If you want something more like proper ship class usage from terran traditions, take a look at the Honor Harrington series. BBs are not only smaller, but older than dreadnoughts in it, and typically aren't used if they don't have to be because they just don't pack the kind of wallop that dreadnoughts do.

I allways got the impression that in sci-fi a dreadnought is usually a big-ass ship with a single uber-weapon (think Homeworld 2 dreadnought), while a battleship is an equally big ship, but with lot's of "smaller" guns.

Then I guess Strattcomm's Archangel suits the class perfectly.

The one built around a HUUUGE big-ass (blue) beam cannon? Yes, that would be a perfect dreadnought. My Archy is a textbook example of a BB on the other hand
