For other starships of the same name, see USS Merrimack.

The USS Merrimack was a Starfleet starship active in 2381. During the invasion of the Borg Collective that year, it was part of a task force to defend Starbase 24 along with the USS Sparta and USS Ulysses. A previously undetected Borg cube slipped through perimeter defenses and attacked the task force, destroying all three vessels and the starbase.

It is possible, although not established, that this is the same vessel as the USS Merrimac
