I have a humanoid creature in my world that can emit and sense waves similar to radar (sort of like a bat with echolocation) and it can also fly at supersonic speeds due to jet propulsion. Does anyone know if it might be possible for an intelligent creature like this to find and disarm/disable a USA-made non-nuclear missile mid-flight assuming a flight duration for the missile from launch to target of 30 minutes? There would be no other aircraft in the sky. The humanoid could already have knowledge of technical information on the missile but wouldn’t have access to proprietary tools (just standard tools, weapons and explosives). What would be the most practical way to disarm the missile?
Swat It Out of the Sky
There are no short-range supersonic cruise missiles in the US arsenal. Your humanoid can somehow travel at supersonic speed, so catching the missile is no problem. It matches speed with the missile, crawls up to the nose cone, and screws a small explosive in place. It then leaves. Boom.
Alternately, it crawls up to the nose cone (or by the stabilizing fins), and takes off. Jet wash from supersonic travel ought to be sufficient to disable the missile.
Additional point to address - missiles are not hard to find - radar would be largely unnecessary. Shooting them down is much harder, but a supersonic humanoid makes that much easier.
