All you need is a lot of cheap, shitty missiles on a lot of cheap, shitty platforms. Three dudes on one dinghy will get got by the .50 cals, 25mm, and Phalanxes (they learned from the Cole in the Gulf of Aden). Lots of dudes on lots of cheap, fast boats with the cheapest, most basic anti-ship missiles will take out any modern surface navy ship. The IRGCN swarm tactics will work.
