I think you are missing the point: they know they cannot win. But if they send 100 missiles and 50 fast boats after a carrier, one might get a lucky hit. THAT is what they are hoping for, it’s counting coup.
We have to change our “concept of winning.”. That is so western. They “win” if the inflict damage on the Great Satan.
I don’t think suicide boats would do any harm. In fact I can’t think of too many things which would work worse, at least if their intent is to ram our ships.
There are other problems tho. The exocet used by the Argentinians showed how vulnerable even high tech ships can be. There are probably naval equivalents to the RPG. It is a slob’s weapon but they can kill a tank, knock down a low flying helicopter etc. It seems countries like Russia, China etc. turn out these mass produced medium tech devices and sell (or give) them to any terrorist country or group who wants them.
If they have hand held missiles which could hit a ship at a mile of so and are aimed rather than guided by radar or GPS or something else which can be defended agianst, we are in trouble.
