Large ship hovering above the Engineer city.

StaffNeomorphApril 18, 2017Wanted to make a topic about that ship.Not sure if there was already a conversation about it before.
In one of the recently revealed scans from the empire magazine we can see what appears to be a large ship hovering above the "Engineer" city.
Back in 2015,way before anything about the film was officialy announced, one of our longtime members BigDave had spoken to someone who claimed that he has worked on Prometheus 2 and provided some very reliable information regarding the film to us.The leaked info was covered in this article.
One of the info mentioned a concept art of another Juggernaut looking ship, that is slightly different in design.

Looking back at the large ship thats hovering above the „Engineer“ city, its pretty much horseshoe shaped and asymmetrical like Shaw and David's Juggernaut in comparison.But unlike the Shaw and David's Juggernaut , that ship is much larger and as mentioned above, is slightly different in design.
It also bears some simmilarities to some of the unused Engineer ships from Prometheus.
I was hoping to see more Juggernaut looking ships in the sequel and I'm grateful to actually see one.
Now I'm wondering,what purpose does that ship has in the film.
If I remember correctly (If this is true), the leak from the SXSW screening described another ship that "entangled" with the Juggernaut.
I suspect that after David bombards the "Engineers" with the black liquid, that larger ship docks with the Juggernaut and something happens.
What are your thoughts about that ship?What purpose do you think it has?Any theories?
