The new general’s first assumption about a swarm attack of small boats against single, large target, not quickly maneuverable US Navy ships, does not make that much sense.
To my understanding, USN vessels all have radar, can spot incoming vessels from any direction, and can fire against them. Sure, if dozens of such vessels converge on an aircraft carrier, it will take some effort. But not so much as would permit serious damage or destruction to a USN vessel.
I am wrong? This new and optimistic Iranian general is dangerous if he things a swarm attack of small speed boats is a match for a USN cruiser, destroyer or aircraft carrier. He is thinking of the USS Cole, which was moored at port, not expecting an attack. None of those assumptions hold in the Straight of Hormuz during war.
Furthermore, it is my understanding that carriers operate with a screen of defensive cruisers, destroyers and submarines. Not to mention their own aircraft. It would take a lot of suicide boats to penetrate the protective screen. This guy is blowing smoke.
