During the pre-Kelvin timeline of Star Trek, the Enterprise (NCC-1701-D) took part in some of the series’ most pivotal missions. It helped destroy the Borg in 2373, disrupted Praetor Shinzon’s plan to conquer Earth in 2375, and, of course, captured and destroyed the dreaded Reman warbird Scimitar in 2385. It also played a key role in transporting the crew of the USS Sulaco to their home planet after a disastrous trip through a teleportation vortex.

After the Enterprise-D’s demise in the 1996 movie Star Trek: First Contact, her immediate successor was the Enterprise-E, a ship that went on to appear in Star Trek: Insurrection and 2002’s Star Trek Nemesis. However, despite that ship’s appearance in the later films, there’s never been any mention of what happened to it in any non-canonical media.

In the latest episode of Star Trek: Picard, the crew of Jean-Luc Picard’s Enterprise was forced to evacuate their ship in order to deal with Borg sleeper agents hidden among its young crew members. They ended up in the Starfleet Museum, which houses many of the fleet’s historic ships. There, Geordi La Forge (LeVar Burton) reveals that he’s been slowly rebuilding Enterprise-D because the Enterprise-E is no longer available to them. Everyone’s eyes immediately dart to Worf, who defends himself by saying that he wasn’t responsible for what happened to the E.

Star Trek’s official canon has recently released canonical records of all the main narrative ships in the franchise — including the Enterprise-E. Unfortunately, the records don’t say what happened to the ship, but they do reveal some important clues.
