A hacked missile vessel could threaten its own task group

What prevents an enemy from hacking Hybrid Navy drones and turning them against British ships?

The command-and-control investment is presumed to help prevent it, but the consequences of a compromised missile ship lead to a preference for keeping a minimal crew aboard.

An uncrewed missile vessel operating inside a task group could cause severe damage if an adversary gained control and fired its weapons. The command-and-control investment is presumed to address that risk, although the discussion supplies no probability estimate or guarantee of protection. Even one compromised missile ship could threaten nearby vessels before the formation could respond. A minimally crewed missile vessel is preferred as a way of retaining people aboard a platform whose weapons create such serious consequences.
