Andorian renegade ship
The Andorian renegade ship was operated by Andorian renegades in the Triangulum system.
This ship was dismantled by the renegades and hidden, leading a Starfleet admiral to believe they had vacated the star system. Jean-Luc Picard recalled this incident in 2366, comparing it to Worf's inability to find any trace of those who had attacked the Rana IV colony. (TNG: "The Survivors")
