This Vulcan cruiser was a type of Vulcan starship that was commissioned sometime after 2152. It shared a similar design lineage with the Suurok-class, but instead of a single "hoop" warp nacelle, it contained three rings arranged in a clover-shaped arrangement.
Upon witnessing the starship class, T'Pol, who doubted the concept of time travel, was able to identify it as a Vulcan cruiser, but did not recognize the configuration. Archer, who was determined to prove time travel was real, noted to her that she did not recognize it because it had not been built yet. (ENT: "Future Tense")
