It's clearly not an invasion or what-not, because the shuttles are landing with landing clearance (else the shield would get in the way).
I am afraid I am going to have to ask for a full starport gear shifting plan, based on the idea that there are too many Imperials around to simply just cart the stuff off unnoticed.
There is an ulterior motive for this request- the Imperial players opposing you in this endeavour have requested a delay based on their current real-life workload, so it won't be resolving for a little while. Hence, you may as well plan.
