Iran military strike possible but could strain defense systems, insiders say

How the United States and Israel coordinated Attacks against Iran continueCurrent and former defense officials say that while a limited attack lasting several days is feasible, sustaining a broader confrontation (potentially involving hundreds of incoming missiles) is much more complicated.

The United States and Israel on Saturday launched a mission known as Operation Epic Fury, targeting Iranian leaders and military sites. Its duration is not yet clear, but the campaign could last days, according to US officials.

Sustaining operations beyond the initial window presents a more complex challenge, shaped by a “zero-sum” competition for missile defense inventories between the Middle East and Europe.

Officials and analysts warn that certain inventories of U.S. air defense missiles and interceptors have been severely depleted by the relentless pace of recent operations. The strategic dilemma for the Pentagon is that the systems needed to protect US bases from Iranian retaliation They are the same ones who are being exhausted by the defense of Ukraine and the current protection of Israel.

Iran has already launched counterstrikes near US positions in Bahrain, Qatar, the United Arab Emirates, Kuwait and Jordan, and several host governments say their air defense systems intercepted the incoming projectiles. As of Saturday, no deaths or injuries to U.S. service members have been reported, a U.S. official told Fox News Digital.

U.S. authorities have not released casualty figures or formal damage assessments.

During the intense June 2025 Iran-Israel conflict, U.S. forces fired more than 150 high-altitude area defense terminal interceptors (about a quarter of the total global inventory) and a large number of standard ship-based missiles to protect allies, according to published defense assessments.

This shortfall is largely attributed to the dual pressure of supply to Ukraine against Russian cruise missiles and the build-up of batteries in the Middle East. Replenishing these high-end systems can take more than a year, analysts say, because production lines are optimized for peacetime and cannot be ramped up overnight.

Independent groups have noted that the United States currently produces approximately 600 to 650 Patriot PAC-3 MSE missiles per year, reflecting recent contracts to increase production capacity. Analysts say that in a high-intensity war with a near-peer adversary like Iran – where multiple interceptors are often used to defeat a single incoming missile – even a year’s production could be consumed in a matter of weeks, especially after recent withdrawals in Ukraine and the Middle East.

“The War Department has everything it needs to execute any mission at a time and place of the president’s choosing and on any timeline,” chief Pentagon spokesman Sean Parnell said in response to questions about readiness.

Retired Air Force Gen. Charles Wald, former deputy commander of U.S. European Command, said the United States retains the ability to send conventional strike munitions to the region and draw on prepositioned stockpiles if a campaign is ordered.

“From a conventional ammunition standpoint, we can always transport more weapons from around the world,” Wald told Fox News Digital. “There are plenty of weapons stored there for this type of mission in mind.”

The biggest concern, he acknowledged, is on the defensive end.

“The problem will be the defensive weapons: Patriot, SM-3 and the Arrow system in Israel,” Wald said. “You can never have enough defense.”

Regional analysts warn that in a sustained missile exchange, interceptor inventories – not offensive strike weapons – could become the binding constraint.

“There is a limit to the number of THAAD missiles that can be used,” said Israeli defense analyst Ehud Eilam. “These are not systems that can be reproduced overnight.”

Iran is believed to possess between 1,500 and 2,000 ballistic missiles, as well as drones and shorter-range rockets capable of attacking US bases and energy infrastructure in the Gulf.

Several experts also noted the psychological impact of recent US operations.

The rapid Operation Absolute Resolve in Venezuela in January 2026 and the 12-day exchange with Iran in the summer of 2025 have reinforced confidence in US military capabilities. However, one former defense official warned that success in these limited-scope missions can create a false sense of momentum toward action in much more complex scenarios.

“Iran is a very different problem,” the official said: a large, heavily armed state with extensive missile forces and regional proxy networks that wouldn’t resemble a short surgical operation.

Wald recognized that risk.

“We don’t want people to feel so confident that they don’t consider the risks. It’s not going to be as clean or pure as it was, say, Venezuela, or the 12-day war.”

Even as attacks continue, officials warn that retaliation by Iran and its network of allied militias could widen the conflict. Iran’s ballistic missiles and drones, along with allied groups in Iraq, Lebanon and Yemen, have already unleashed missile salvos against US bases and Gulf partners, according to defense reports.

Experts say the 2025 conflict underscored how quickly an escalation can test both defensive systems and political will.

“Once these things are broken, you own what comes next,” one former official said, underscoring the risk that missiles and indirect actions could quickly expand a limited US attack.

Wald warned that even a successful military phase would not eliminate political uncertainty.

“Bombing Iran will not bring about regime change,” he said, emphasizing that air power can degrade capability but cannot guarantee a stable political outcome.

Beyond the immediate exchange, officials say the economic consequences could prove equally important. About a fifth of the world’s oil supply transits the Strait of Hormuz, and even a limited disruption could send global energy markets sharply higher.

For Washington, the strategic calculation extends beyond the Middle East. China remains the main long-term competitor, and the war in Ukraine is already consuming significant resources.

A sustained regional conflict would draw on naval assets and air defense systems that planners must also consider for possible future contingencies in Taiwan or North Korea.

Officials familiar with internal deliberations say the President donald trump has sought a high degree of confidence in how an Iran contingency would play out, a standard that becomes more difficult to meet in scenarios involving escalation and political consequences.

Fox News Digital has reached out to the White House for comment.
