cpxxs hit the nail on the head. A modern military aircraft is a system of systems, and integrating them in even a more conventional aircraft is beyond the capabilities of all but a few industrial nations. On a low-observable aircraft, it's doubly difficult. The USAF spent untold millions of dollars and thousands of hours in super-computer time just to develop the radome on the nose of the F-22. The mockup pictured in the news article, even if it was a full-sized, high quality model (which it is not) would be nothing more than a stage prop. As it is, it's neither of those, and looks all the world like an up-scaled GI Joe toy (I believe some mentioned this earlier). It is not stealthy (you'll have to take my word that I know something about this) at even the most basic level, let alone at the multiple levels that go beyond simply geometric shape. Metallurgy, computer hardware and software, electromagnet computational capability, composite materials engineering...the list goes on and on, and all of it needing to be integrated (systems engineering on steroids) into a functional weapons system. Designing and building a basic atom bomb is actually easier, particularly if you're only trying to make a couple. This Iranian project is pure propaganda, and likely intended for internal or at best, regional consumption.
