A relentless wave of Iranian missile and drone strikes has brought the air defense reserves of Persian Gulf nations to the verge of total depletion, raising alarms among Western allies regarding the sustainability of global military supply chains.
According to a recent Bloomberg report, Iran has launched approximately 1,200 ballistic missiles and 4,000 "Shahed" unmanned aerial vehicles at Gulf states since February 28. Standard air defense doctrine dictates firing two interceptors per target, a mathematical reality that has rapidly consumed regional stockpiles.
The Gulf states have relied heavily on Patriot PAC-3 and GEM-T interceptors to thwart the incoming attacks. Prior to the outbreak of hostilities, these nations held fewer than 2,800 of these missiles. This estimate is based on US Foreign Military Sales (FMS) data and assessments from defense experts, who note that actual delivered quantities may be even lower than approved orders.
"Without active US support, most countries would have nothing left to defend themselves against Iranian missiles," warned Kelly Grieco, a senior fellow at the Stimson Center.
To shoulder the defensive burden, the United States has deployed a massive amount of its own precision weaponry. Anonymous sources familiar with the operations revealed that US forces have launched hundreds of Tomahawk cruise missiles, valued at $2 million each, alongside more than 1,000 Joint Air-to-Surface Standoff Missiles (JASSM), which cost $1.5 million apiece.
The expenditure rate drastically outpaces manufacturing capabilities. Before the conflict, the US stockpile contained roughly 4,000 Tomahawks, with RTX Corporation producing only about 100 annually. Similarly, government documents indicate Lockheed Martin's maximum output for JASSMs this year is capped at 860 units.
The rapid consumption of high-tech munitions suggests a calculated pivot in US defense strategy. Peter Layton, a former Royal Australian Air Force officer, observed that allowing such depletion implies Washington either does not anticipate an imminent conflict with China or expects a swift resolution if one occurs.
"Strategically, this means the Trump administration views Iran as the most important problem and is willing to risk it to destroy it," Layton noted.
While the US Department of Defense maintains it has adequate munitions to fulfill its immediate missions, the drain on resources is causing global unease. The Washington Post reports that the Pentagon is currently weighing the controversial option of redirecting air defense interceptors initially earmarked for Ukraine to the Persian Gulf.
Defense officials in France and Germany are already reporting strain in weapon supply lines. Military analysts caution that while the high usage rate of Patriot and other interceptors is yielding short-term tactical successes, it threatens to expose the US military to significant strategic vulnerabilities in the medium term.
