There certainly is...recently put on the market by a private Russian concern.
See article here:
there has been reports of china building these superships. There was a book written a while back about chinese invasion of the world, and they used superships, some were pure missile ships and would overwhelm defenses by sheer volume of incoming fire and some were massive troop transports. It was called Invasion. Sure it was a fictional story, but when I saw the article about these massive ships being built and the secrecy around them, makes one wonder.
Do you mean the Club-K Missile System?

They do those every month.....
As for a CSLBM test.... surface ships are easy to track. If it was from another Nation state, then it would be all over the news, 35 miles is NOT far for any aircraft to fly, shoot KTLA could have a bird up and over the “launch site” in under 20 minutes if it wanted to.....
There is more to this for sure.
