Iran rapidly restores missile arsenals, exposing limits of U.S. bombing campaign

The bombing campaign that consumed weeks of American and Israeli firepower has left Iran's underground missile network scarred but not crippled. Satellite imagery analyzed by CNN tells a story of rapid recovery: since a ceasefire took hold in mid-April, Iranian crews have already reopened fifty of the sixty-nine tunnel entrances that coalition forces had buried under rubble and collapsed rock. They've filled bomb craters with dump trucks and earth movers. They've repaved roads that were cratered to prevent missile launcher movement. The work is unglamorous, low-tech, and it is working.

This recovery exposes a fundamental asymmetry in the conflict. The United States and Israel deployed sophisticated, expensive munitions to achieve what military planners call tactical success—the suppression of Iranian missile forces through weeks of sustained bombardment. But tactical success, experts warn, does not guarantee strategic victory. Sam Lair, a researcher tracking Iranian missile capabilities at the James Martin Center for Nonproliferation Studies, put it plainly: the U.S. military excels at achieving tactical wins, but without a coherent war strategy and a viable theory of victory, those wins can become strategic failures. "There is nothing preventing the launchers from being armed with the broad stockpile of missiles the Iranians still possess," Lair said.

That stockpile is substantial. Intelligence assessments suggest Iran maintains roughly one thousand missiles stored in deep underground facilities—some buried under hundreds of meters of rock. The depth that makes these bases so difficult to destroy also means the missiles themselves likely survived the surface-level attacks. During the initial weeks of conflict, when American and Israeli forces focused on collapsing tunnel entrances and destroying the roads that connect them, Iranian missile fire was significantly suppressed. But suppression is not elimination. Once the ceasefire began, the repair work accelerated. At a base near Isfahan, where coalition forces had created at least eighteen separate craters trying to seal four tunnel entrances, satellite imagery from early May showed dump trucks filling those craters. Two other entrances at the same facility had already been reopened, and the roads leading to them had been repaved.

President Trump has made the destruction of Iran's missile arsenal a centerpiece of his war aims. In a March post on Truth Social, he listed the "complete degradation of Iranian missile capability, its launchers, and everything related to them" as one of five core objectives. The Iranian network of underground bases, constructed over more than two decades, was designed precisely to withstand this kind of assault. The depth and distribution of the facilities limit the options available to American and Israeli planners. Early in the conflict, they chose to attack the entrances—a strategy that, combined with efforts to locate and destroy individual launchers, achieved a dramatic reduction in Iranian missile launches. Satellite images from that period showed facilities like the North Isfahan Missile Base devastated by multiple strikes, with debris covering tunnels and destroyed launchers visible outside.

But the campaign against Iran's missile production infrastructure may prove equally difficult to sustain. The U.S. and Israel conducted a broad effort to damage the supply chain—from factories producing small electronic components to facilities manufacturing rocket motors and missile bodies. When the ceasefire was announced on April 8, U.S. Defense Secretary Pete Hegseth suggested the damage was permanent. "You'll be digging out launchers and missiles, but without the capacity to replace them," he said. "You no longer have a defense industry." Yet American intelligence assessments now indicate Iran is already rebuilding critical military capabilities, restarting drone production and replacing missile launchers and production capacity. Some of the same factories targeted in the recent campaign had already been reconstructed by the time satellite imagery was analyzed—the same facilities had been hit during the Twelve-Day War last year and repaired then too.

Timur Kadyshev, a senior researcher at the Institute for Peace Research and Security Policy at the University of Hamburg who studies Iranian missiles, noted the asymmetry with a touch of irony. "They've been preparing for this kind of war for twenty years," he said. "They're very prepared." The disparity in technology and cost is stark. Destroying a missile base requires sophisticated, expensive weapons deployed by advanced militaries. Repairing one requires tractors. One Iranian official told CNN that the Iranians have "exceeded all the timelines the intelligence community predicted for reconstitution." As Iran continues to restore access to its arsenal and rebuild its production capacity, analysts are growing concerned that the ongoing threat posed by that arsenal is being underestimated—particularly given the shrinking inventory of American missile interceptors. The preliminary agreement between the U.S. and Iran to reopen the Strait of Hormuz remains incomplete, with months of negotiation ahead. If hostilities resume, Iran will be positioned to continue launching missiles as long as it has launchers, crews, and the vast stockpile it has already preserved.
