Satellite images reviewed by AP show construction at missile sites in Parchin and Shahroud, where buildings housing mixers appear under repair.
“If they’re able to reacquire some key things like planetary mixers, then that infrastructure is still there and ready to get rolling again,” said Sam Lair of the James Martin Center for Nonproliferation Studies.
Solid-fuel missiles are central to Iran’s deterrence strategy after Israeli strikes decimated much of its air defense.
Iran operates solid-fuel missile production facilities at Khojir and Parchin, both near Tehran, as well as at Shahroud, about 350 kilometers (215 miles) northeast of the capital. All three sites were struck by Israel in October 2024, during earlier hostilities between the two countries.
Experts say the June strikes appeared designed to destroy buildings housing mixers, the machines essential for evenly combining missile fuel.
Iran had been producing more than 200 solid-fuel missiles a month before the war, according to AP.
Iran fired more than 570 ballistic missiles during the conflict, depleting an estimated third of its arsenal, according to the Jewish Institute for National Security of America.
Western officials believe Tehran could try to source mixers and propellant chemicals from China, which has previously supplied materials for Iran’s missile program. Beijing said it supports Iran’s sovereignty but voiced “deep concern” over rising regional tensions.
Iran’s Defense Minister Aziz Nasirzadeh said last month the country was now focused on producing “military equipment with higher precision and greater operational capabilities.”
