For the incident in the early 24th century, please see Tomed Incident.

The Tomed mission was conducted by the Vulcan High Command sometime during the first half of the 22nd century.

During the mission, Talok, a Romulan operative in disguise, served under T'Pol. (ENT: "Kir'Shara")

As T'Pol assumed her position at the Vulcan Compound on Earth in 2149, the Tomed mission must have taken place before that.
This mission might possibly have a connection to the Beta Quadrant star Tomed.
