Warp drive is a form a faster-than-light travel. Human ships used warp drive by the 26th century and even into the 51st century.
Before Human life even began, the Jagaroth created space ships that used warp drive. The drive could be set at Warp 1, Warp 2, or Warp 3, however, Warp 3 is suicide if the ship did not have fully working warp drive. (DW: City of Death)
Human ships of the 26th century were powered by antimatter, which may be required for warp drive. Should the navigational computers be tampered with while a ship is in warp drive, it could disintegrate. (DW: Earthshock, The Girl in the Fireplace)
Warp shunt technology, used by the Nestenes to reach Earth in 2005, could have been a form of warp drive. (DW: Rose)
