Vulcan Shuttles were about two decks high, and had a warp-ring drive, similar to most Vulcan starships of the time. At least one was assigned to Suurok-class starships.
The Sh'Raan sent a shuttlecraft of this type to pick up Ambassador V'Lar from Enterprise in 2151. This type of shuttle was also used as ground-based transportation, on Vulcan. In 2154, a shuttlecraft of this type transported Ambassador Soval to the Vulcan High Command building, which had an external landing pad. [Source: wikia]
