A Lelari battle cruiser was a Lelari starship, equivalent in size to an Excelsior-class starship. Lelari battle cruisers were equipped with cloaking devices. In 2372, the USS Cantabrian faced three decloaked Lelari battle cruisers, ordered to escort Cantabrian crew member Benjamin Caldwell to Lelar Prime to face charges. One Lelari battle cruiser towed the Cantabrian, the latter of which was ordered to become sensor-blind, to the Lelari homeworld. (Star Trek: The Cantabrian Expeditions: "Breaking Benjamin")
