Why a 'loyal canoe' cannot be inserted into the world wars

How would World War I or World War II navies use modern loyal-wingman-style uncrewed surface vessels?

They could not adopt the concept in isolation because the required data links, remote weapon controls, and command systems would transform every crewed warship as well.

Remote control of a separate armed craft requires communications, data transfer, and weapon-control capabilities unavailable to historical fleets. Once those systems exist, navies can also centralize and remotely operate weapons aboard their crewed ships, creating armored combat information centers and changing warship design so broadly that the original counterfactual loses a stable baseline.
