Interesting, Iran producing torpedoes. The only practical use for such torpedoes, that I can think of, is to try to sink a blockade. Or, it could just be a propaganda stunt - "Hey, you Americans and Zionists, don't even try it - you'll drown in your own blood."
Also interesting is the drones, in that Iran did not turn on their radars, and won't be doing so indefinitely. It also means that if a fleet of F-16's or F/A 18's comes over to say hello, they won't know it until it's too late. Hopefully, though, no bombs will be necessary to acheive regime change.
Those torpedoes are imported from China!
