What you want is a Nimitz-load of Douglas Skyraiders on patrol.Then,when a skipper calls in to say he is being attacked,the nearest Skyraider (as used for COIN in Vietnam) goes in and strafes the pirate skiffs with her Browning fifties.Otherwise, the only way to really solve the problem is to institute a convoy system for all mercantile vessels transiting those waters,although the idea of air-lifting small detachments of Marines by helo to US and allied ships appeals,too------surely it should not prove to be too difficult logistically,and would provide some useful live-firing exercises, no ??
