The J-class was a type of freighter operated by the Earth Cargo Service in the early 22nd century.

Technical specifications[]

Ships of this type had a maximum speed of Warp 2, were equipped with hull plating and primitive inertial dampeners, and could transport up to 30,000 metric tons of cargo. Their warp drives were personally designed by Zefram Cochrane. (ENT episode: "Horizon")

They were eventually superseded by the larger and faster Y class. (ENT episode: "Horizon")

The class remained in service into the 23rd century. In the period around the late 2230s and early 2240s decade, Travis Mayweather served as captain of the modified Class-J cargo tug SS New Rochelle. It ferried colonists from Earth to Tarsus IV. (TOS reference: The Autobiography of James T. Kirk)

Variants of this class remained in use by various nations into the 2260s of the Kelvin timeline. (ST video game: Fleet Command)
