The Tsuranga was a 67th century hospital ship which was attacked by a Pting when the Thirteenth Doctor, Yaz, Graham, and Ryan were aboard.
The crew during this time included just Astos and Mabil, while the rest of ship's function was entirely automated, and powered by and anti-matter drive. Patients aboard the ship were Yoss Inkl and Eve Cicero who was with her brother Durkas Cicero and consort Ronan. (TV: The Tsuranga Conundrum)
