Howdy!
I found an extremely anomalous ship in Special Modifications. The L-2783 Deep Space Recovery Vessel (pg. 64) is strange.
Just from the description, this Sil 5 (Bulk Freighter) has a 5000 Enc capacity, carries 50 (most likely Sil 2) salvage pods, and 4 cargo shuttles (most likely Sil 4, but maybe Sil 3).
In addition, it can hold an "old-style cruiser" in it's internal bay (text description).
It has a crew of 100 and passengers of 100.
It can perform repairs in deep space.
I can't get enough HP to meet the crew/passenger, cargo and hangar capacity.
