Hot off the presses!
Here with the latest and newest addition to the Iranian military arsenal.
A flying boat of indigenous design and manufacture, apparently pretty sophisticated from what I see.
"Iran unveils squadrons of flying boats"
NOT having, at least in the initial "mark", a formidable capability. At this point, merely a surveillance aircraft not possessing much in the way of an offensive threat?
"The craft, dubbed the Bavar 2, is armed with a machine gun and carries surveillance cameras"
"bloggers poked fun  at Iran’s so-called stealth technology, saying the flying boat looked like something anyone could buy in kit form from mechanical magazine ads."
I am NOT poking fun at the Bavar. This could very well be one more area of concern for the U.S. Navy. These little itty-bitty flying boats COULD in the future pose a challenge to an aircraft carrier or any other American warship for that matter.
The Iranians will be able to produce this low technology but still "stealth" type of flying boat in profusion. That is whole point of using such low technology. You can build with relative ease a whole bunch of these flying boats very cheaply, deploy them considerable numbers, disperse to any location WHERE THERE IS WATER and attack targets in the low-level attacker mode!
[it would interesting to know if Bavar works well in the ground-effect mode!]
If any of the Bavar are ever able to carry a TORPEDO, we may very well see in the future a type of combat as last seen almost seventy years ago now - - during the Battle of Midway ? A concentrated mass of Bavar in numbers overwhelming defenses!
An asymmetrical attack weapon? See what you will. My conclusions differ with that of the "experts"? You decide for yourself.
