NextFin News - The Israeli Air Force has shifted the focus of its aerial campaign toward Iran’s "missile cities," a vast network of hardened underground silos and storage facilities, marking a decisive transition into the second phase of a conflict that has rapidly redrawn the geopolitical map of the Middle East. Following the initial suppression of Iranian air defenses and the destruction of over 300 surface-level launchers in late February, Israeli military planners are now deploying specialized bunker-busting munitions to neutralize the Islamic Republic’s most resilient strategic assets. This escalation follows a week of unprecedented kinetic exchanges that have already seen the United States and the United Kingdom join defensive operations after Iranian strikes targeted regional bases and international shipping lanes.
The shift in targeting logic reflects a calculated gamble by the Israeli security cabinet to strip Tehran of its "second-strike" capability. While the first phase of the war focused on immediate threats—mobile launchers and command centers—the current operations target the deep-earth infrastructure located in the Zagros Mountains and beneath the central desert plateaus. These sites, some buried more than 500 meters deep, house the bulk of Iran’s medium-range ballistic missiles, including the Fattah and Kheibar-Shekan variants. By forcing the conflict into the subterranean realm, Israel is attempting to achieve what decades of sanctions could not: the physical dismantling of Iran’s primary deterrent.
Military analysts suggest that the success of this phase hinges on the performance of the GBU-72 Advanced 5,000-pound penetrator and potentially the American-made GBU-57 Massive Ordnance Penetrator (MOP), though the latter’s use remains a subject of intense speculation. The technical challenge is immense. Iranian engineers have spent years reinforcing these "cities" with layers of high-strength concrete and shock-absorbing materials designed to withstand conventional strikes. However, the precision of modern intelligence—bolstered by advanced satellite imagery and human assets on the ground—has allowed Israeli jets to target the specific "choke points" of these facilities, such as ventilation shafts and elevator portals, effectively sealing the missiles inside their tombs.
The regional fallout has been immediate and severe. As Israel intensifies its strikes on the Iranian mainland, Hezbollah has fully entered the fray, launching drone swarms and rocket volleys from southern Lebanon. This multi-front pressure has forced the Israel Defense Forces (IDF) to maintain a residual ground presence in Lebanon while simultaneously managing the high-intensity air war over Iran. The entry of the United Kingdom into the coalition, following a strike on a British base earlier this week, has provided the U.S.-led effort with critical logistical support and additional naval assets in the Persian Gulf, further isolating Tehran.
Economically, the markets are reacting with a mixture of volatility and grim pragmatism. While oil prices initially spiked above $110 a barrel, they have since stabilized as traders bet on the coalition’s ability to keep the Strait of Hormuz open. The strategic objective for U.S. President Trump remains the containment of the conflict to prevent a total global energy shock, even as his administration provides the intelligence and refueling support necessary for Israel’s deep-strike missions. The White House has maintained a delicate balance, supporting Israel’s right to dismantle the missile threat while signaling to Tehran that a total regime-collapse scenario is not the immediate goal—provided the missile fire ceases.
The coming days will determine if Iran’s "passive defense" strategy can survive the most sophisticated aerial assault in modern history. If Israel succeeds in collapsing the entrances to the underground complexes, the Islamic Republic will find its primary lever of regional influence—its missile hegemony—functionally erased. Yet, the risk of a "nothing to lose" response from Tehran remains high. With its surface launchers depleted and its underground cities under siege, the Iranian leadership faces a binary choice: a humiliating retreat from its regional ambitions or a final, desperate escalation that could draw the entire globe into the fire.
