USS Lantree (Ouroboros class)

The USS Lantree was a Federation starship, a tier 6 temporal raider in Starfleet service in the 31st and 26th centuries. 

Service history
In the 26th century, the Lantree was part of an allied fleet, with representatives from the 22nd century to the 31st, dispatched by Temporal Agent Pavel Chekov to defend the USS Enterprise (NCC-1701-J) during the assault on the Tuterians' command sphere. The Lantree subsequently engaged Temporal Liberation Front forces from various factions, including Krenim, Vorgons, Terran Empire, Na'kuhl, and Sphere Builders.
