“Live long and prosper.”
– Science Officer Spock, USS Enterprise NCC1701
The Jellyfish was a late-24th century starship commissioned by the Vulcan Science Academy for the transport of red matter. It was described as being “our fastest ship” and featured a rotating tail section.
After the ship’s commissioning in 2387, Ambassador Spock piloted the Jellyfish during his attempt to save the Milky Way Galaxy from destruction by a massive supernova before it destroyed the planet Romulus. Spock used the Jellyfish to inject red matter into the supernova, resulting in the creation of a black hole that absorbed the nova. While the plan succeeded, Spock was unfortunately too late to stop the nova from destroying Romulus.
As Spock was attempting to depart, he was intercepted by the Romulan mining vessel Narada, and both ships were pulled into the black hole. The Narada emerged from the tunnel through space-time in 2233 and was the catalyst for the alternate reality, whereas the Jellyfish exited the black hole twenty-five years later. Upon capture by Nero, the ship was stored inside the Narada. Nero later ordered the use of the red matter aboard the seized ship to destroy the planet Vulcan.
The ship was destroyed when the younger Commander Spock of the alternate reality was able to retrieve the ship and piloted it on a collision course with the Narada, igniting the red matter inside. Spock survived the collision and was beamed aboard the USS Enterprise at the last moment.
