Iran Rushes to Rebuild Missile Program After Israel War Devastation

Just months after a devastating 12-day war with Israel that shattered its defenses and depleted its arsenal, Iran is racing to resurrect its ballistic missile program, satellite imagery reveals. Yet, amid frantic reconstruction at key production sites, a critical gap persists: the absence of massive planetary mixers essential for crafting the solid fuel that powers these rapid-fire weapons, according to missile experts analyzing the efforts.

The June conflict, which erupted on June 13, 2025, with Israeli airstrikes on Iranian nuclear, military, and energy infrastructure, marked a brutal escalation in decades of shadow warfare. Israel, backed by U.S. strikes on June 22, targeted over 100 sites, including air defenses and missile facilities, in a bid to cripple Tehran's nuclear ambitions and retaliatory capabilities. Iran fired back with more than 550 ballistic missiles and over 1,000 suicide drones, striking Israeli cities, a hospital, and military bases. The barrage, codenamed Operation True Promise III, caused civilian casualties and tested Israel's vaunted Arrow missile shield to its limits, with some projectiles breaching defenses and hitting urban areas like Bat Yam and Haifa.

By war's end on June 24, Iran had expended over a third of its estimated 2,500-missile stockpile—around 904 projectiles in total, per the Washington-based Jewish Institute for National Security of America (JINSA), which maintains close ties to the Israeli military. The strikes left Iran's air defenses in tatters, forcing Tehran to prioritize missiles as its primary deterrent against future Israeli aggression. "Missiles are Iran's lifeline now," said Sam Lair, a research associate at the James Martin Center for Nonproliferation Studies. "Without them, they're vulnerable to another preemptive hit."

Satellite images from Planet Labs PBC, captured this month and scrutinized by the Associated Press, expose reconstruction fever at three major solid-fuel missile hubs: Khojir and Parchin near Tehran, and Shahroud, 350 kilometers northeast. At Parchin, damaged mixing buildings—prime targets for Israeli precision strikes—are undergoing visible repairs, with scaffolding and earth-moving equipment on site. Similar activity buzzes at Shahroud, where not only mixing facilities but ancillary structures, like storage silos and assembly halls, are being rebuilt at a breakneck pace. "The speed here is telling," Lair noted. "Iran's pouring resources into missiles over even its bombed nuclear sites, which show far less activity."

These solid-fuel missiles, unlike their liquid-fueled predecessors, can launch in seconds, evading destruction on the pad—a tactic Israel exploited during the war to neutralize dozens mid-prep. Pre-conflict, Iran was churning out over 200 such missiles monthly, a production surge that prompted Israel's June blitz. Experts like Carl Parkin, a fellow at the James Martin Center, believe the strikes zeroed in on mixing as the production chokepoint. "Israel knew disrupting those planetary mixers would hobble output," Parkin explained. "Iran has the casting molds and assembly lines ready—if they snag those machines, they could ramp back to high volumes fast."

Planetary mixers, with their orbiting blades mimicking planetary motion for superior blending, are industrial behemoths vital for homogenizing solid propellants. Destroyed or seized in the attacks, replacements are scarce; Western sanctions bar sales, leaving China as the prime suspect supplier. U.S. officials have long accused Beijing of funneling missile components to Tehran, including propellant chemicals that likely sparked a deadly April port explosion in Iran, killing at least 70 and derailing nuclear talks in Oman. Just days later, Washington sanctioned Chinese firms for exactly that.

Footage from an Israeli raid on a Syrian missile site near Masyaf—allegedly IRGC-operated—captured a planetary mixer eerily similar to Chinese models sold online, hinting at Iran's proxy procurement networks. Iran's recent high-level Beijing visit, where President Masoud Pezeshkian hobnobbed with Xi Jinping at China's Victory Day parade on September 2, fuels speculation of quiet deals. Though no specifics emerged from the trip, China's Foreign Ministry reiterated support for Iran's "sovereignty and security" while expressing "deep concern" over Middle East tensions.

Tehran's urgency spikes with looming U.N. sanctions, potentially snapping back this month to punish missile advancements. President Pezeshkian, addressing the U.N. General Assembly today, is expected to decry the measures as aggression, vowing resilience. Iran's U.N. mission stonewalled AP queries on the rebuild, but Defense Minister Gen. Aziz Nasirzadeh boasted on August 22 of "new missiles with advanced warheads," crediting the war for sharpening priorities toward "higher precision and operational capabilities."

Analysts warn that full restoration could embolden Iran, turning the 12-day war from a setback into a mere pause. Can Kasapoglu, a Hudson Institute fellow, argues Beijing could turbocharge Tehran's arsenal with guidance systems and microprocessors, making strikes harder to preempt. "If China steps in, this isn't defeat—it's a speed bump," Kasapoglu wrote. Lair echoes the peril: "At prewar production rates, sheer volume overwhelms Israel's intercepts. And Iran won't bargain these away—ever."

As Tehran scrambles for mixers, the world watches a high-stakes arms race unfold. With U.S. intelligence still assessing Iran harbors no active nuclear weapon program—per March testimony from Director Tulsi Gabbard—the missile buildup risks tipping the fragile post-war balance toward renewed conflict. For now, Iran's facilities hum with defiant reconstruction, but without those elusive machines, its roar remains a whisper.
