There is no indication that any of these systems have precision terminal guidance in the normal sense of the term, nor evidence that Russia or China have solved the engineering problems related to it.

The US has deployed hypersonic missiles with precision terminal guidance, though not strike weapons, for almost 20 years in more limited domains. However, given the longstanding US doctrine to not deploy a hypersonic attack weapon without precision terminal guidance, and the demonstrated engineering capability in the domain, it is reasonable to assume that Dark Eagle has this capability. Any information about how the terminal guidance works will be closely guarded; it has no obvious engineering solution and it took the US several decades to figure it out.

A bunch of things in that article are incorrect or misleading. For example, the kill chain latency model isn't correct in several respects. It looks like an AI mashup of popular internet slop.
