Star Cruiser/Legends

Star Cruiser was a term used to describe either large Imperial or Mon Calamari warships

Its use was similar to the use of "Star Destroyer" to refer to various types of Imperial warships, although most likely chosen to differentiate the Rebel warships from the more intimidating Imperial vessels.

Rebel use
The Mon Calamari line of warships, ranging from Imperial destroyer-sized vessels like the MC80 Star Cruiser and including larger Calamari battleships like Home One and its sister ships, were referred to as Star Cruisers, and were perhaps the most common Star Cruisers.

Imperial use
Star Cruiser was also a term utilized by the Imperial Navy. In this instance, it formally denoted Super Star Destroyers which were lesser in size and strength than Star Battlecruisers and Star Dreadnoughts. Their size-range began at several times the size of the Imperial-class Star Destroyer and ended somewhere below the size of vessels like the Executor-class.
