A large Starfleet class of the 2250s, represented by Admiral Anderson's flagship USS Europa, which was rammed by a cloaked Klingon vessel at the Battle of the Binary Stars.
The Nimitz class is one of the bigger Starfleet designs created for the first season of Star Trek: Discovery, a broad ship with twin hulls beneath its saucer.
Its one prominent appearance is in Battle at the Binary Stars. The USS Europa arrives carrying Admiral Brett Anderson, who takes charge and offers T'Kuvma a ceasefire. As the two sides talk, a Klingon cleave ship drops its cloak and ploughs straight through the Europa's saucer. The crippled flagship destroys itself, taking the Klingon vessel with it and killing the admiral, a loss that ends any hope of stopping the war at its first battle.
