USS Lassiter

The USS Lassiter was, along with the Potemkin one of the two main Starfleet starships which comprised the initial response to the Borg/Cybermen invasion of Delta IV. It was destroyed almost immediately. (IDW: Assimilation²)

Behind the scenes
Though not seen in any great detail, the ship appeared to be of the Excelsior-class, perhaps made most famous as the kind of ship Hikaru Sulu eventually captained in Star Trek VI.
