A class 9 warp core of an Intrepid-class starship
The class 9 warp drive was a type of warp drive developed by Starfleet in the 24th century for the Intrepid-class starships. The warp drive allowed the starships to achieve the top sustainable cruise velocity of warp 9.975. (VOY: "Caretaker", "Relativity")
The warp core had a tricyclic input manifold. (VOY: "Relativity") This system was designed to provide a maximum output of four thousand teradynes per second. (VOY: "Drone") It could operate for up to three years before refueling. The reaction chamber was equipped with a compositor, which allowed recrystallization of the vessel's dilithium. (VOY: "Innocence")
The USS Voyager was the first starship to test the class 9 warp drive in deep space in 2371. (VOY: "Relativity")
