I think it's a bit unfortunate that hive species are always paired with bio-technology and bug like architecture.
Well you could go with a AI biased machine "hive" But we kinda have one.
Something similar is a psychic collective. They can be anything but are all of sorta 1 mind.
I think we tend to default to Bees or ants as they are major examples of a monarchical like group collective.
When Humanity goes into the stars (Thanks Musk) we may encounter other life that forms similar social structures.
Humans can be hive like in nature we just need to toss out this silly notion of self determinism.
In this concept I imagine a evolving planet of life forms that from a supportive ecosystem. The fleet is not just bugs. Its psudo jelly fish, Space lobsters, or space snails, possibly fish. Think if evolution didn't go the land route. Ocean world animals evolving together and attaining a collective mind.
