During the Borg invasion of 2381, the Gibraltar was assigned to defend the planet Korvat, along with the USS Alexey Leonov. Although the USS Enterprise-E signaled the vessels to stand ready for an incoming Borg cube, there was little resistance the vessel could provide without transphasic torpedos. When the Borg attacked the planet itself, the Gibraltar put itself in the beam's path, sacrificing itself. (ST - Destiny novel: Gods of Night)
