The Titan raider was a class of spacecraft used by the Humans from Titan for dilithium raids on Earth in the late 32nd century.
These ships were equipped with phasers more advanced than that of the USS Discovery. These older ships were not like other raiders seen by Michael Burnham and Cleveland Booker, as they were overcrowded and straining beyond their means. One of the ships was commanded by Wen in 3189.

In Star Trek Online, this class of ship is called the Jovian-class.
