A Xindi cruiser was a type of cruiser employed by the Xindi during the 22nd century When it was discussed that Degra had given the crew of Enterprise NX-01 the coordinates of the Xindi Council, and thereby may launch an attack on the Council, he assured his compatriots that "Archer's ship [is] heavily damaged. They wouldn't stand a chance against one of our cruisers." (ENT: "E²") As Degra was stating this information, the type of vessel he was speaking of was presumably Xindi-Primate, perhaps even the Xindi-Primate starship he was aboard at the time of the discussion.
