The Myhr'an super battle cruiser was a large Myhr'an starship, of a similar configuration to a Myhr'an battle cruiser but nearly 800 meters long. In 2372, the Myhr'an super battle cruiser was a part of the Myhr'an fleet accompanying the Myhr'an planet killer. Like other Myhr'an ships, the super battle cruiser was equipped with a cloaking device, used to escape after the Myhr'an defeat at Canaileus Prime.
