Claustrum

The Claustrum is a Maximal prison ship.

Beast Wars: Uprising
Sentenced to incarceration in Garrus-16, Rampage and Trans-Mutate were loaded on board the Claustrum. The ship was shot and destroyed en route near the dwarf planet LGC-8803, though both Rampage  and Trans-Mutate safely made it to the planet below. Lord Imperious Delirious later admitted to having destroyed the ship, intending to salvage technology or soldiers.
