USS Mount Shasta
The USS Mount Shasta was a Federation California-class starship operated by Starfleet in the late 24th century.
In 2381, the Mount Shasta was rallied by Beckett Mariner to create an armada of California-class starships sent to defend their sister ship, the USS Cerritos, from the USS Aledo. After successfully destroying the Aledo, the armada went to Douglas Station. (LD: "The Stars At Night")
The Mount Shasta was presumably named for Mount Shasta, California.
