Quote - sounds like all the bases are covered. There was a Japanese cartoon (in America it was called Starship Yamato)..which was the size of a large battleship...wait.. it was a large batteship..;) I'm not sure if it predates Star Wars, tho..

The Argo was designed to resemble the WWII battleship Yamato, so, yes, it was the size of a battleship.
 
The other EDF (Earth Defense Force) battecruisers were actually larger than the Argo. And the ships with the dual wave-motion guns were much larger. In fact, by the time of the "Comet Empire" series, the Argo was one of the smaller ships in the fleet!
 
The Comet Empire was actually a massive starship within a moon-sized ship, which was then covered with a comet-like shielding.
 
P.S. In the US, the series was called "Star Blazers". Season 1 was "The Quest For Iscandar", season 2 was "The Comet Empire", and season 3 was "The Bolar Wars".
In Japan, the series' title was translated to be "Spacebattleship Yamato", "Be Forever Yamato", and "Arrivederci Yamato". Sorry, I don't know why the last series was translated into Italian!
