Israel to Attack Iran’s Underground Missile Sites in Second Phase of War
IDF Shifts Focus to Deeply Buried Ballistic Missile Facilities as Conflict Escalates

Israel’s military campaign against Iran is entering a new and more intense phase, with fighter jets reportedly set to attack ballistic missile sites buried deep underground across Iranian territory, according to sources familiar with the operations. This renewed push reflects a broader strategic effort to degrade Tehran’s ability to launch aerial attacks on Israeli cities and regional targets while deepening the conflict with one of its most formidable adversaries.
The surge in operations comes as the U.S.-Israeli air campaign enters its second week, following initial strikes on Iranian leadership and military targets that sparked retaliatory attacks across the Middle East. With above-ground missile launchers already targeted, Israeli commanders are now turning their attention to the deeper, more fortified infrastructure that houses much of Iran’s ballistic arsenal.
Transition to the Second Phase of Operations
According to sources, the conflict is now moving into what military planners describe as a second phase, marked by strikes on underground missile storage sites and bunkers — some of the most protected assets in Iran’s military network.
“These are deeper targets, often protected by mountains of earth and reinforced concrete,” a source told Reuters. Israel’s strategy appears designed to neutralize Iran’s long-range strike capability before the conflict can escalate further, focusing on ballistic and cruise missiles that could threaten Israeli cities or U.S. bases in the region.
In a statement, the Israeli military confirmed that fighter jets struck “an underground infrastructure site used by the Iranian regime to store ballistic missiles and aircraft-targeted ordnance” overnight. Details on location and operational outcomes remain classified.
Strategic Goals of Targeting Underground Sites
The focus on deeply buried missile facilities serves several strategic purposes:
Eliminating Iran’s long-range strike capability: Tehran’s inventory of ballistic missiles, estimated by Israeli sources at around 2,500 before the war, poses a credible threat unless degraded. Targeting underground storage sites reduces Iran’s ability to launch missiles against Israel and allied positions.
Exploiting air dominance: Control of Iranian airspace by Israeli and U.S. forces allows fighter jets and drones to strike deeper into Iranian territory with reduced risk of interception.
Weakening Iran’s military resilience: Destroying hardened missile bunkers undermines Tehran’s confidence in its long-standing strategy of sheltering key assets underground to survive airstrikes.
Recent assessments indicate that Iran’s reliance on underground bunkers — sometimes called “missile cities” — has created predictable targets, leaving key launch points exposed once above-ground defenses were neutralized.
Hurdles and Uncertainties
Despite the escalation, significant uncertainties remain regarding the effectiveness of these strikes and Iran’s potential responses. Tehran continues to conduct missile and drone attacks on Israel and allied interests even as above-ground assets are targeted.
Estimates of Iran’s remaining ballistic missile stockpile vary widely. While Israeli sources cite around 2,500 missiles before the conflict, some analysts suggest the number could exceed 6,000, reflecting decades of accumulation.
There is also debate over the resilience of Iran’s underground facilities. Deep bunkers can be vulnerable if entrances or ventilation systems are hit, but precision strikes on such hardened targets require advanced intelligence and specialized munitions.
The Broader Conflict Landscape
Targeting underground missile sites occurs amid intensifying regional conflict. Early airstrikes in late February targeted Iranian leadership and military positions, reportedly killing senior commanders and provoking Iranian retaliatory strikes, including missiles and drones aimed at Israel, U.S. bases, and regional proxies in Lebanon, Iraq, and Syria.
The U.S. military has supported Israeli operations with airpower and intelligence, emphasizing the campaign’s goal of reducing Iran’s ability to threaten regional peace. However, both nations remain cautious about triggering broader escalation.
The conflict’s impact has extended beyond the battlefield. Gulf nations have bolstered air defenses, and global markets are reacting to potential disruptions in shipping lanes, including the vital Strait of Hormuz, underscoring the war’s far-reaching implications.
Diplomatic and Regional Implications
Strikes on Iran’s most protected military assets carry diplomatic consequences. Neighboring states and global powers are closely monitoring Israel’s expanded campaign, weighing how deeper incursions into sovereign territory could affect regional stability.
Iranian leaders have pledged to continue their operations despite losses, emphasizing that the destruction of underground missile sites will not cripple Tehran’s overall military capabilities. However, losing control of its missile arsenal — a key pillar of defense doctrine — represents a significant strategic setback.
Looking Ahead
As Israel enters this next phase of operations, critical questions remain: How far will the Israeli air campaign penetrate Iran’s hardened underground facilities? How will Tehran respond to the attacks? Will international pressures prompt diplomatic engagement?
The next weeks may reveal whether striking underground missile sites will significantly degrade Iran’s capabilities or simply escalate a conflict that continues to challenge regional stability and global security.
Key Takeaways
Israel is entering a second phase of war against Iran, targeting underground missile bunkers and storage sites.
Fighter jets, supported by U.S. intelligence, have already struck some of these facilities.
The goal is to neutralize Iran’s long-range missile capabilities and reduce threats to Israeli cities and U.S. bases.
Estimates of Iran’s remaining missile stockpile vary, complicating strategic calculations.
Expanded strikes reflect a broader escalation with both regional and diplomatic implications.
Israel’s focus on underground missile sites marks a turning point in the war, with the potential to reshape Tehran’s military posture, affect regional stability, and influence the conflict’s trajectory in the coming weeks.
