You can have one hypersonic missile with a little payload that may hit a stationary target
Kinzhals, Kh-15, Zircons are all guidable during all trajectory. That was the main goal for their creation. They developed to hit moving targets since the beginning, that was the main idea - to make an insanely fast missile that could make evolutions at that speed and avoid any possible countermeasures. Creating missile body that will sustain hypersonic speeds was not a hardest task. Guiding was the main problem. Principles of controlling supersonic aircraft is very different from those of conventional plane. Same with difference between supersonic and hypersonic flight. You can't just take supersonic guided missile and put more fast engine on it. That will not work.
And about a little payload. Hypersonic is not only payload, it is also a projectile with enormous momentum that will easily penetrate nearly everything. So, you have a destruction from the blast and a penetrative destruction from the projectile itself, that is very useful for sinking large ships.
Or like 10000 conventional missiles... For the same price.
Really, hypersonics are not 10000 more expensive than conventional missile, but OK.
It is proven that conventional missiles could be intercepted, and any large military ship have antimissile system on bosrd. So, while you trying to hit aircraft carrier with tons of conventional missiles, enemy will have enough time to detect the source and rise fighters into the air to destroy it.
So, no, it is not "same thing for same price". Either you spend 1 expensive hypersonic with guaranteed result and you are safe, or you spend 10000 conventional missiles with a possibility that target will hit back.
