Mods are asleep, post the Wing Commander III mini-shuttle.
It's one of the destructible cargo units that attach to the Confederation transport.
Attachments like these were pretty bugged and a bunch were cut from the game late. Here's the set that were intended to attach to the latticework on the Kilrathi freighter!
Unfortunately the bug persisted into Wing Commander IV and so the Confederation transports are all naked. Which is too bad given the number of convoy-related missions you fly! (And: the aforementioned Kilrathi transport.)
