A class of crewless, computer-controlled Starfleet ships promoted by Admiral Les Buenamigo in 2381 as a replacement for the California class, which turned on their makers in Star Trek: Lower Decks.
The Texas class is small, fast and heavily armed, and needs no crew. Buenamigo presents it as a safer way to do the second-contact work of the California class. In Trusted Sources the first ship, the USS Aledo, saves the Cerritos from Breen attackers at Brekka.
In The Stars at Night it emerges that the ships run on code Rutherford wrote before his memory was altered, and that Buenamigo staged emergencies to show them off. When he removes the Aledo's restraints to silence the Cerritos, the ship kills him, wakes its sisters Dallas and Corpus Christi and attacks Douglas Station. The Cerritos lures them away and ejects its warp core, which destroys the Dallas and Corpus Christi, and a fleet of California-class ships brought by Mariner finishes off the Aledo.
