The game Star Trek: Armada has eight kinds of ships, that can be considered a cruiser:

Depiction	Name
	Sphere
	Assimilator
	Akira
	Steamrunner
	Vor'cha
	SuQ'jagh
	Griffin
	Raptor

In general the Sphere, Akira, Vor'cha and Griffin can be considered to be the light cruisers. However, as the Steamrunner, Raptor and SuQ'jagh can be considered having another role than cruiser (artillery/assault ship), the distinction in light and heavy cruiser is negligible.

The cruisers are not as fast as the destroyers but not as powerful as battleships. In the early- and mid-game they are the backbone of any armada. In greater numbers they are devastating.

Depending on the selected techtree the ships are available at the tier 1 yards either after building the tier 1 research station or right from the beginning.
