This is merely propaganda to convince the US to return to war. Iran possesses no Aladdin's lamp it can rub and magically regenerate destroyed infrastructure.
I believe there is some truth to the Israeli leaks. Iran has prepared for this conflict for 40 years and likely would have spare planetary mixers in storage and masked sites for solid fuel. It also was tipped off about a pending war in June 2025 when it fought an 12 day war with Israel and likely spent the next 9 months procuring whatever it could anticipating another round.
In fact, Marco Rubio admitted to as much as saying they couldn’t let Iran get to the point that it could make hundreds of missiles a month while they could only produce tens of interceptors.
We saw when IDF raided a secret Syrian missile base during the war a couple years ago that Iran had managed to build a modest mixer underground in a mountain site to produce short range BMs. So it’s clear from that example, that Iran can make missile underground. The question is at what rate.
But the real breakthru might be that Iran has rotated to “gel fuel” rather than solid fuel. There was articles in the past talking about this breakthru fuel which could mix benefits of solid fuel with the practicality of liquid fuel.
Relying on indigenous expertise and the relentless efforts of its scientists, Iran has achieved complete self-sufficiency in producing solid missile propella...

If I am correct then the main problem for Iran would be carbon fiber production capabilities and if any of that has been moved underground. If not, then Iran would have to use steel casing for engines which makes them heavier and reduces range for distant targets like Israel, but for short range targets like the Persian gulf this isn’t a problem.
We shall see. I don’t think the issue right now is missiles, but willpower. For Iran, it seems more content on waiting for oil to eventually bite rather than be in a skirmish.
Large scale bombings of Iran stopped in April, so it’s now been about 5 months that Iran has had to rebuild and recover and bring in materials from Russia and China via plane, railroad, and Caspian Sea.
