I think he's talking about the Galaxy Mrk III Listed in some novels and supposedly appearing at the end of the Dominion War... Basically a Galaxy with Intrepid and Soverign class tech like EMH, bio-nueral computers, etc...
and while you could debate till doomsday if the Super-Dreadnought Galaxy-X is cannon, It definitely doesn't belong in fleet ops
lol, I think you give the Galaxy 3 too much credit.
It actually never appeared in any reliable source. I only like it because it seems to be what a post-dominion war retrofit of the Galaxy would look like, with the more sovy-ish hull and soxy nacelles, and a sovy deflector dish as well. It's just like the relation between the Constitution class and the refitted Constitution class (e.g. Ent-A). Too bad I lost my pics of it.
Oh, btw do you have a pic of the Phobos anywhere?
