USS Premonition

The Premonition was a Federation timeship that travelled back to 2376 to warn Captain Picard and the Federation of an iminent Borg invasion by Locutus. Under the command of Captain Deming, the Premonition was originally badly damaged after being pursued into the past by two Borg Spheres, before being assisted by the USS Enterprise-E. Deming and his ship stayed to assist the Federation repel the Borg threat, and participated in the battle for Earth. Locutus's Cube was destroyed but he managed to escape in a Borg Sphere fleeing back in time to destroy the USS Enterprise-D shortly after it’s first mission to Farpoint Station. Fortunately the USS Premonition followed Locutus back and destroyed the Sphere before it could attack the Enterprise and alter history. (TNG game: Armada).
