Now after reading Historical Liberation of Terra I
Dreadnought = Galactica all the way
considering the dreadnaught itself might as well have been the Galactica with all of those autocannons (if it flies it dies)
Yeah the design suggested it the AC/5's were a dead give away the fluff in Reunification promoted it but the story in the Liberation of Terra I "Last Stand of the Grand Old Queen" page 78 killed it for me, everything about the story screamed Galactica taking elements from the old and new series to make a great story.
Even the ending seemed very fitting
