USS Endeavour (NCC-71805)

The USS Endeavour (NCC-71805) was a Nebula-class Federation starship that served in the late 24th century.

In 2368, the Endeavour was assigned to the Starfleet blockade force at the Klingon-Romulan border during the Klingon Civil War. Later that year, the ship was assigned to a patrol circuit in the Cleon system. (TNG: "Redemption, Part II", "The Game")

Captain Amasov of the Endeavour was at some point involved in a conflict with the Borg sometime prior to 2371. After the battle, Amasov reflected, "...It is my opinion that the Borg are as close to pure evil as any race we've ever encountered." (VOY: "Scorpion")

In 2373, the Endeavour faced the Borg at the Battle of Sector 001. (Star Trek: First Contact)
