The standard Tellarite starship of the 2150s, whose appearance was copied by a Romulan drone ship in 2154 to set the Andorians and Tellarites against each other.
Tellarite cruisers are seen in the fourth season of Star Trek: Enterprise. In Babel One, Enterprise is taking Ambassador Gral's Tellarite delegation to trade talks with the Andorians when it picks up Shran and the survivors of his ship, the Kumari, who say a Tellarite vessel destroyed them.
Enterprise is then attacked by what looks like an Andorian ship, and Archer's crew work out that one raider is behind both attacks. It is a remotely piloted Romulan ship using holographic emitters to imitate other vessels, meant to wreck any alliance in the region. In United the Tellarites agree to put their ships alongside those of Earth, Vulcan and Andoria in a single sensor net to find the drone, an early step towards the Federation.
