USS Enterprise (Waypoint)

The USS Enterprise was a Federation starship commanded by Geordi La Forge which contained the consciousness from Data's positronic brain within the starship's mainframe. While Data projected several holograms of himself and operated all other stations of the Bridge, completely, a full complement of staff was kept elsewhere on the ship.

History
A month after Data's physical form deteriorated and he was uploaded into the Enterprise, he and Geordi were sent to intercept the cube-shaped Federation shipwrecked timeship Sakurazaka, with a crew of 200, from the distant future. Any attempts at communicating failed, but they discovered it was being run by its own artificial intelligence. Data determined the vessel's repeated transmission of a code was its own future-version of the Prime Directive, the preventative cause of communication in the first place. When the Sakurazaka's artificial intelligence opened a communication with Data, it denied allowing the Enterprise to transport the crew. The Sakurazaka then set itself to self-destruct and Data attempted to beam their crew aboard the Enterprise. In order to distract the other ship, Data uploaded himself to and engaged the Sakurazaka's operating system. As the Sakurazaka exploded, taking Data with it, the Enterprise was able to escape with the other crew before the Enterprise could be destroyed as well. ("Puzzles")
