What is the registry of Picard's Enterprise in First Contact?

The registry of Picard’s Enterprise in Star Trek: First Contact is NCC-1701-E.

The Enterprise-E is a Sovereign-class starship introduced after the Enterprise-D was destroyed in Star Trek Generations (1994). It became the primary vessel for Captain Jean-Luc Picard and the rest of the Star Trek: The Next Generation crew in First Contact, Insurrection, and Nemesis.

First Contact places the Enterprise-E at the center of a time-traveling battle against the Borg. The ship pursues the Borg sphere to Earth in the 24th century, then follows it into the past to protect humanity’s first warp flight and preserve the timeline.

A common mix-up is NCC-1701-D, which was Picard’s ship in The Next Generation and Generations. NCC-1701-E is the next Enterprise in the lineage, while NCC-1701-B belongs to the earlier film Star Trek Generations. The Enterprise-E’s sleeker Sovereign-class design was created specifically for the film series.
