“Iran no doubt is seeking to establish the ability to produce the underlying components and materials used to make complete missile systems and subsystems, which also means it must import associated production equipment and technology. But Iran remains dependent on importing many such components and materials, as well as their constituent subcomponents and materials.48 Key items that Iran apparently continues to seek from abroad include:
• Guidance technologies to increase missile accuracy like gyroscopes, navigational sensors, gyrocompasses, and accelerometers;49
• Ultra high-strength steels and high-grade aluminum alloy used to make lighter rocket bodies for longer-range liquid-propellant missiles;50
• Ball bearings for use in liquid-propellant rocket engines;51
• Valves, electronics, and measuring equipment suitable for use in ground testing of liquid-propellant ballistic missiles and SLVs;52
• Production equipment and feedstock material for high-quality carbon fiber and aramid fiber (kevlar),53 used to reduce weight in missile components like solid rocket motor cases (and thus increase missile range);
• Graphite cylinders that are machined to make heat-resistant lightweight missile parts like nozzle throats and re-entry vehicle nose tips (which again can help increase missile range);54
• Tungsten metal powder and tungsten-copper alloy plates used to make jet vanes for thrust vector control systems.55
Iran has obtained such items in the past, and likely will continue to do so in the future, from entities in China, North Korea, and Russia.56”

Again you made a claim that Iran’s missile program is entirely self reliant on raw materials and guidance systems. That claim is without proof as well.
Personally, I think Fateh costs are more in the range of 200-300K and the inhibitor is not in fact
cost, but quality materials needed to “finish” each missile that Iran still imports. Or else even with a cost of $200K per missile, Iran could stockpile tens of thousands Fateh missile if the missile was entirely built FROM SCRATCH within Iran.
We know that is not the case because Iran’s space program and missile program has been tainted with defected parts/materials by US/Israel/EU in attempt to cause doubt in supply chain of Iran.
