NextFin News - The high-intensity aerial campaign conducted by U.S. and Israeli forces against Iranian targets has reached a critical inflection point as stockpiles of sophisticated interceptor missiles approach exhaustion. Since the escalation began on February 28, 2026, U.S. Central Command (CENTCOM) reports that coalition forces have struck over 10,000 targets within Iran. However, the sheer volume of munitions required to maintain both offensive pressure and a defensive shield has created a "bottleneck of industrial physics" that now threatens the sustainability of the mission.
A detailed analysis released this week by the Royal United Services Institute (RUSI), a London-based defense think tank, estimates that allied forces expended 11,294 munitions in the first 16 days of the conflict alone, at a staggering cost of approximately $26 billion. The report, co-authored by U.S. Air Force Lieutenant Colonel Jahara Matisek, suggests that Israel has already depleted roughly 81% of its pre-war inventory of Arrow interceptors. Matisek, whose research often focuses on the intersection of military strategy and industrial capacity, warns that these high-end stocks could be completely spent by the end of March if the current rate of fire persists.
The depletion is most acute in the upper tiers of Israel’s multi-layered defense array. The Arrow 2 and Arrow 3 systems, designed to neutralize ballistic missiles in the upper atmosphere and space, are being consumed faster than global production lines can replace them. Unlike consumer electronics, these interceptors—costing between $1.5 million and $2 million per unit—rely on specialized supply chains that cannot be scaled rapidly. This scarcity has forced tactical shifts; recent reports from the Israeli financial outlet Calcalist indicate that the military has begun utilizing the medium-range David’s Sling system to intercept threats typically reserved for the Arrow, a move intended to preserve the most advanced stocks for existential threats.
Andreas Hörnedal, a research leader and air defense expert at the Swedish Defence Research Agency (FOI), notes that while offensive operations allow for a degree of "self-determination" in choosing which munitions to conserve, defensive systems offer no such luxury. Hörnedal, who has long maintained a cautious stance on the endurance of Western-style high-tech defense in prolonged conflicts, argues that a weakened shield directly exposes both civilian populations and strategic military assets. He points out that Iran has spent decades preparing for this specific scenario, developing a resilient and advanced military infrastructure that contrasts sharply with the insurgent forces the U.S. has faced in recent decades.
The strategic implications of this "interceptor gap" are already manifesting on the ground. A malfunction in a David’s Sling battery earlier this week allowed Iranian ballistic missiles to strike near Dimona and Arad, areas critical to Israel’s strategic interests. While the Israeli military maintains that its interception rate remains "outstanding" at over 90%, the reliance on a dwindling number of interceptors creates a mathematical certainty of diminishing returns. If the defensive umbrella thins, coalition aircraft may be forced to fly riskier, deeper sorties into Iranian airspace to neutralize launchers at the source, further escalating the human and material cost of the war.
Despite the alarming projections from RUSI, some industry figures offer a more resilient outlook. Pini Yungman, a reservist Brigadier General and president of the defense firm TSG, asserts that Israel’s accelerated production schedules since late 2023 have significantly bolstered its capacity. Yungman argues that Israel can currently produce interceptors at a pace that rivals or exceeds Iran’s ability to manufacture ballistic missiles. This perspective, however, remains a minority view among independent analysts who cite the global shortage of solid-rocket motors and specialized sensors as a universal constraint on all high-end missile production.
The conflict now enters a phase where "industrial endurance" may dictate the diplomatic outcome. Jean-Loup Samaan, a senior researcher at the Middle East Institute of the National University of Singapore, suggests that Israel is currently balancing three high-risk options: mixing missile systems to mask shortages, allowing drones to hit unpopulated areas to save interceptors, or intensifying the offensive campaign to "degrade Iran’s capabilities before the clock runs out." As the calendar turns toward April, the ability of U.S. President Trump’s administration to replenish these stocks while maintaining domestic readiness will be the ultimate test of the "Arsenal of Democracy" in a new era of peer-state warfare.
