I'm not talking about making missiles or mass produced missiles or AI guided missiles. Hypersonic has an exact definition (Mach 5+) and calling something a hypersonic missile should set off your bullshit detector. In ballistic missile terms usually there is only a short portion of its flight that is hypersonic, but that doesn't make it a hypersonic missile. The western definition of a hypersonic missile is sustained hypersonic flight in the atmosphere. Russia and China define hypersonic missiles as hypersonic at any point in their flight likely for propaganda purposes.

It's only the bit right before it hits where in needs to be hypersonic, isn't it? Fast enough to avoid interceptors. It's why if Taiwan ever turns hot, the plan is for all the US navy boats to do a strategic retreat.

No, that's the China, Russia definition.

Fast enough to avoid interceptors.

Ballistic trajectories still have a long arc that makes it easier to detect and deploy countermeasures. It's how patriot, iron dome, and other systems are allowed to work.
