Any proof that iran managed to reverse engineer the stealth coating found on the RQ-170.Iran produced that coating long before interception of RQ-170.
this is the stupidest idea I have ever heard firing a 300 km cruise missile off of a speed-boat or from land is by far less costly, more stealthy effective and survivable than firing from a fighter jet. its just a waste of money and time.I still think Qaher with its wing configuration was a surprise antiship missile carrying vehicle. I think it was suppose to fly low to surface just like the flying boats (Ground Effect Vehicle) and carry passive sensors and anti ship cruise missiles beyond the 300km range of the coast. Unlike the current fleet of flying boats, this would take off from San air base and then drop to low altitude as it gets closer to its targets... But I'm just speculating with nothing to back it up. But I'm approaching it from asymmetrical doctrine of IRGC, it makes sense for this to be another antiship killing vessel.
It's more important to reverse engineer and improve the engine of a mig-29 or/and buy a number of Su-35s with ToT.
