The USS Song (NCC-325084) was a 32nd century Federation Courage-class starship operated by Starfleet. In 3189, it was stationed at Federation Headquarters. (DIS: "Die Trying")
When Osyraa managed to infiltrate Federation Headquarters aboard the USS Discovery, Admiral Charles Vance ordered ships within Headquarters' perimeter to prepare to open fire, causing the Song to move to an offensive position. (DIS: "There Is A Tide...")
Once Osyraa opened fire on the fleet inside from Discovery inside the shield, the Song was among the ships that fired back. (DIS: "That Hope Is You, Part 2")
In 3190, J'Vini stole a shipment of dilithium from the Song, the first of four identical thefts she would commit. (DIS: "Choose to Live")
This ship has the second highest registry number of Federation starships, after the USS Relativity (NCV-474439-G).
