The first ship of this class, the Kumari, was commanded by Commander Thy'lek Shran from 2142 to 2154. (ENT: "Babel One") Since their launch in the 2140s, several Andorian warships of this type had been reported missing. When the Enterprise NX-01 was attacked by a Romulan drone-ship disguised as an Andorian battle cruiser, Shran suggested that the Tellarites may have been responsible, using one of these missing ships after enhancing its systems. (ENT: "Babel One") In 2154, several Andorian battle cruisers were incorporated into an Andorian-Tellarite-Vulcan fleet which consisted of some 128 ships, formed in response to a Romulan marauder that threatened the entire region. (ENT: "United") In the mirror universe, the Andorian rebels utilized this class of vessel to engage the Terran fleet in 2155. At least two of these vessels were among the rebel ships attacking the ISS Avenger. (ENT: "In a Mirror, Darkly, Part II")
