An undockable megaship Thomas Class Bulk Cargo Ship SOD-6497 present in system Xihe orbiting planet 2. I encountered a Medusa at the scene, which when I approached, scanned me and flew off. Looks like it is supposed to be looted using the new megaship looting system introduced in 3.1. At the time of writing, this is an anarchy system, so the vessel can be attacked freely without consequences (although it does have some defensive turrets). I tried re-instancing the megaship and each time a bunch of emergency medical ships were in the area, some of them type 9, some type 7. With a sufficiently powerful ship, it is possible to mine (without incurring bounties) these large medical emergency ships for materials such as Chemical Manipulators. They rapidly jump system when attacked, so you must take them down fast. However more always seem to appear.
