It's (scarily) available in the commercial sector[1][2] from space if you have the need to purchase their services.

Suffice to say, military and intelligence agencies are probably a few generations ahead of this and you won't find them commenting on strategic capabilities on HN.

Thanks! Technically, what do you think is the biggest obstacle to achieve military grade hopping? Is it just cost, or something you simply cannot buy from open market AND cannot make one if you have the knowledge?

Military frequency hopping / spread spectrum isn’t really about preventing being noticed, it’s more about making it harder to jam. If you don’t have physical safety from the people “more powerful” than you who want to stop you, then they will still locate you easily and stop you using physical force.
