The Enterprise is a Sovereign-class starship operated by Starfleet, the exploratory and defensive service operated by the United Federation of Planets. Though I cannot detail either the ship's defensive or offensive capabilities, I can tell you that it is presently the most advanced vessel in the fleet; it is the sixth ship to bear the name of Enterprise, and has been on active duty for one year, thirty-eight days. It is equipped with impulse propulsion and warp engines, capable of a sustained cruising speed of warp factor 9.7 and a maximum speed of warp 9.9.
