In an alternate timeline in which Khan Noonien Singh won the Eugenics Wars, the Yamato was a Khanate Earthfleet battlecruiser in service during the mid-24th century. It was under the command of Princeps Varley.
In 2369, the ship was destroyed by an Iconian data-phage. Helot Ezri Dax survived, retained some element of the alien code, weaponized it, and used it to disable the Defiance in 2376. (ST - Myriad Universes novella: Seeds of Dissent)
