T-3

A T-3 unit was a droid employed on the ice planet Akuria II during the Galactic Civil War. Older and sturdier than the more modern astromech droids, the T-3 units were resigned to service aboard Snow Flyers, where they apparently had a primary role in the craft's operation and could not function without them. It's unknown what relation these units had with the ancient T3-series utility droid but comparing their usage, it's possible that the two droids may have been one and the same.

Behind the scenes
The T-3 unit is mentioned by Colonel Odan in the short comic, The Kingdom of Ice, published many years before the release of Star Wars: Knights of the Old Republic which contained the T3-series utility droid. However, in-universe, it may be inferred that the two droids are of the same design.
