The USS Wells was a Federation shuttlecraft in service in the 27th century. It was capable of traveling through time. Voula piloted the shuttle back through time to visit the birth of Starfleet in the early 21st century, attempting to prevent a Romulan ship from altering the timeline. When the shuttle landed, it was damaged, but it was capable of repairing itself over a period of time. The shuttle was also infested with Tribbles. (ST performance: Star Trek Live)
