Category:Heavy cruiser

In starship classification, a heavy cruiser is a large multi-purpose starship, a term sometimes used synonymously with battle cruiser. While the Federation considered their Constitution-class starships to be heavy cruisers in their heyday, the Klingons referred to the same vessel, in their terms, as a battle cruiser. (Star Trek III: The Search for Spock)

Ambassador-class starships were also considered heavy cruisers. (TNG: "Conspiracy")

In an alternate timeline, the Ambassador-class was simply referred to as a cruiser. (TNG: "Yesterday's Enterprise")
