Pralim class

The Tellarite cruiser was a Federation heavy cruiser starship type operated by the Tellarites. The Tellarites bought these ships from Arkonian ship-builders since at least the 22nd century. By the 23rd century, these were replaced by the technologically advanced Tellarite heavy cruiser. 

Specifications
In the 2150s, Tellarite cruisers did not stand a chance against two Andorian battlecruisers. At the time, Tellarite cruisers were green-tinted. Their engines emitted a green glow as well. 

By the 2270s, Tellarite heavy cruisers were brown and visually indistinguishable from Arkonian destroyers. However, their weaponry had been greatly improved. Heavy cruisers were armed with red phasers and photon torpedo launchers. A Tellarite heavy cruiser was a match for a Starfleet heavy cruiser. 

Cruiser
In the 2150s, Tellarite cruisers were the mainstay of the Tellar Space Administration. Ambassador Gora bim Gral stood on the bridge of a cruiser at one point. 

In 2154, Tellarite cruisers were part of a combined Andorian-Human-Tellarite-Vulcan fleet formed to detect two Romulan telepresence drone ships attempting to sow dissent in the region. The allied effort let to the founding of the Coalition of Planets in 2155. 

On November 10, 2163, a small fleet of Tellarite cruisers was involved in a standoff with rogue Human colonists, who occupied the Voortrekker asteroid in the Iota Pegasi system. Captain was in charge of the Tellarite fleet. The dispute was resolved through negotiation by Captain T'Pol and Lieutenant Commander Hoshi Sato of the USS Endeavour (NCC-06)).

Heavy cruiser
On stardate 7101.6 (2270), Commander Brog's heavy cruiser engaged the Constitution-class starship USS Enterprise (NCC-1701) before the two ships joined forces to investigate the fate of the Lavota Wind. 

Mirror universe
In the mirror universe, a Tellarite cruiser was destroyed by the USS Defiant (NCC-1764) in 2155.
