Fiscally, I can't really see the need for this, we already have such a system to deliver a bomb to anyplace on Earth within 30 minutes that has been available since the late 1950's, the ICBM.

And an ICBM launch has a heat signature that can be seen from orbit.

Visualize a hypersonic cruise missile that can be launched from a jet over the ocean, without such a huge heat signature, and which would hit without any advance warning within an hour of launch.

Or hit North Korea from South Korea in 7 seconds... Just because it can do long distance doesn’t mean it has to.
