In starship classification, a mining vessel was a starship designed to conduct mining operations in space. Such vessels were equipped with technology and personnel to recover and process desired materials.
The Narada was a Romulan mining vessel commanded by Nero. After the destruction of Romulus in 2387, Nero used his ship to capture the Jellyfish, which was under the command of Spock. Nero held Spock responsible for Romulus' destruction, for failing to halt the supernova in time. He attacked the Jellyfish during Spock's effort to use a black hole to stop the supernova, but this effort led to his ship being thrown back in time, where an alternate reality was created.
