A shrewdness of apes, an unkindness of ravens, a murder of crows...I wonder how to call a collection of spaceships often seen in the proximity to my planet that is apparently a fruit of a particular kind of alien intellect in every occasion?
A constellation of satellites. Almost everything is a satellite of something, so the ships wouldn't even need to move to a parking orbit first...
Questions that engender list answers aren't really on topic here, aside from the fact that it's all opinion. That being said, I tried to come up with names that express the intelligence of the ships (not just inanimate objects) as well as their interconnectiveness.
