Its things like that which make me glad I’m not in the Navy anymore... area denial weapons.
I know the Russians sold some to China along with Sovremenny destroyers that use them, and some to Syria (Bastion system).
Expect Russia to eventually provide them to Iran as an extended middle finger to the West over sanctions.
I don’t know what defense we have against these, but I’ve been told the Phalanx can shred them. But when something’s coming at you that fast and that close, even if you hit it, pieces and large chunks will still arrive. Here’s hoping something better has been developed.
Iran is getting something if they give Russia a naval base at the mouth of the Persian Gulf
