At the same time, the five-month war with Iran has left a deep mark on American missile inventories. According to estimates cited by Reuters and other American sources, approximately 65% of Patriot interceptors and roughly 38% of THAAD interceptors have been consumed since the start of the conflict. The result is an unprecedented strategic paradox: The US is attempting to build the missile defense shield of the future at a time when it is struggling to replenish the missile stocks of the present.
Golden Dome: The "umbrella" Trump wants over America
The Golden Dome represents Washington's effort to establish an integrated missile defense network capable of detecting, tracking, and intercepting threats long before they reach American soil. The architecture of the program calls for a combination of ground-based and space-based sensors, interceptors, command and control systems, and advanced technologies, with a particular emphasis on space capabilities. The goal is exceptionally ambitious: establishing a multi-tiered defense against ballistic, hypersonic, and other long-range missile threats. The operational logic differs significantly from that of a standard Patriot battery.
The Patriot serves as a crucial final layer of defense. The Golden Dome aspires to create a broader early detection and interception grid so that incoming threats can be engaged across multiple stages.
185 billion dollars and the bill keeps rising
The cost of the Golden Dome has already escalated from its initial estimate of 175 billion dollars to 185 billion dollars as additional space-based capabilities were incorporated. General Michael Getlein has made it clear that the program demands immense resources. The question now being raised in Washington is whether the American state can simultaneously fund:
the Golden Dome, the replenishment of Patriot missiles, the replenishment of THAAD batteries, the production of Tomahawk cruise missiles, long-range missile programs, the defense needs of Ukraine, as well as military commitments across the Middle East and the Indo-Pacific. And herein lies the core vulnerability of American planning.
The great contradiction: A new shield while old ones empty
The Golden Dome project arrives at a moment when existing US air defense systems have suffered massive depletion. Based on an estimate from the CSIS, available Patriot inventories now sit below 1,000 interceptors, while THAAD stockpiles have dropped to roughly 250. Meanwhile, Reuters reported that the US has utilized nearly the entirety of its stockpiles for certain long-range missiles, including ATACMS systems and Precision Strike Missiles (PrSM). A similar picture is being recorded regarding Tomahawk cruise missiles. At an earlier stage of the war, hundreds of Tomahawk missiles were expended, with a Post report indicating that more than 850 were launched within the first four weeks alone. The problem is twofold: the American military machine is consuming missiles at a far faster pace than industry can replace them.
Patriot: The loudest alarm bell
The Patriot system represents perhaps the most characteristic example of this crisis. Estimates indicate that roughly 65% of the US inventory of Patriot interceptors has been expended since the start of the war with Iran. This represents a massive consumption of a weapon considered critical not only for US forces but also for Washington's global allies. The complication is that Patriot units are not deployed exclusively in the Middle East. Ukraine relies significantly on Patriot batteries to counter Russian ballistic missiles, while European nations hold limited stockpiles of their own. Thus, a vicious cycle is created: Iran expends Patriot interceptors, depleted available stocks place pressure on Ukraine as well as pressure on Europe, escalating the demand for boosted American production.
THAAD: Reduced "heavy" stockpiles as well
The identical issue is surfacing with THAAD, one of the primary American systems for intercepting high-altitude ballistic threats. Available estimates point to a stockpile reduction of approximately 38% since the outbreak of hostilities. The CSIS estimates that active THAAD interceptors stand at roughly 250 units. This indicates that pressure is not isolated to the "final wall" of defense, but spans across multiple tiers of the broader US missile defense architecture.
And now the Pentagon presses defense industry
The situation has now raised major alarms at the Pentagon. American leadership is pushing defense contractors to drastically scale up the manufacturing of missiles and interceptors, as the operational demands generated by the war with Iran have laid bare the limits of current manufacturing capacity. The administration wants to ramp up production of both Patriot and THAAD systems, but output for advanced missile systems cannot be expanded overnight. It requires specialized factories, skilled personnel, raw materials, electronic components, rocket motors, and new assembly lines—all of which require years to implement. And that represents the primary bottleneck.
The Golden Dome cannot solve the immediate crisis
The Golden Dome may serve as a long-term strategy for the US. However, it offers no solution for the immediate operational shortfall. If Washington requires more Patriot batteries and THAAD units today, a system still in its development phase cannot bridge the existing gap. This explains why the surrounding debate on the Golden Dome has taken on a vastly different tone. It is no longer just about how advanced American defenses will be in 2030 or 2035. It centers on whether the US can reach that point without completely depleting its existing weapon stockpiles in the interim.
Ukraine adds even greater pressure
The problem becomes even more complex due to the ongoing situation in Ukraine. Kyiv faces acute shortages of air defense interceptors, and NATO has recognized the urgent necessity to accelerate deliveries of critical air defense systems. Europe is attempting to scale up its own industrial manufacturing, but building new industrial capacity requires substantial time. Consequently, the US government finds itself facing a core strategic dilemma: Hold onto Patriot interceptors for its own forces and potential contingencies, or continue supplying allies? There is no easy answer available.
And behind everything stands China
The ultimate nightmare scenario for the US Pentagon is not limited to the ongoing conflict with Iran. It is the prospect of having to simultaneously or sequentially manage a high-intensity war against a peer competitor, namely China. In an Indo-Pacific conflict, the expenditure rate of long-range missiles would be astronomical. In that scenario, Washington would require far greater quantities than it currently demands in the Middle East. This is why the debate over American stockpiles has transcended mere logistics. It has evolved into a fundamental question of national defense strategy and global deterrence.
Trump's massive gamble
The Golden Dome is therefore far more than just another procurement effort. It represents Donald Trump's attempt to forge a new generation of American missile defense during an era in which the older architecture is under unprecedented strain. The challenge is that Washington is being forced to execute two massive tasks at once: build the future while replenishing the past. Namely, funding the 185 billion dollar Golden Dome project while simultaneously restoring depleted stockpiles of Patriot, THAAD, Tomahawk, ATACMS, and PrSM munitions. All of this is occurring while geopolitical threats show no signs of receding.
The real test for the US
The fundamental question is no longer simply whether the US possesses the financial capital to build the Golden Dome. The question is whether it possesses the industrial capacity and necessary time to construct it while simultaneously replacing the munitions consumed in current conflicts. Because if the US requires years to replenish its military warehouses while adversaries can manufacture missiles and drones at significantly higher rates, the challenge ceases to be merely financial. It becomes a challenge of long-term strategic endurance. And the Golden Dome, no matter how ambitious, will ultimately be judged not by how impressive the final system appears, but by whether the US defense industrial base can produce fast enough to cover today, tomorrow, and the next major conflict simultaneously.
