Speaking of, imagine someone sending a satellite full of "ICBM" to space, covertly enough. How do you identify what it is? It's even harder than finding submarines if there's enough "chaff" launches. Dead Hand is a toy in comparison. You have no chance to intercept as the delay is too short and speeds are orbital. Better hope your spies know which satellites are weapon platforms. Cruise missiles are already extremely hard to defend against, in as much as doing so requires the defender to identify all nearby ships, submarines, airplanes and other covert launch points. (ECM is not good enough, SAM also has no chance. Cannons and interceptors have low chance of spotting these as well.) Hypersonic version does not bring all that much to the table there, if anything.
