WASHINGTON: Israel has informed the United States that its stockpile of ballistic missile interceptors is running critically low as the conflict with Iran intensifies, according to Semafor Media quoting the US officials.
Officials said Israel had already entered the current confrontation with limited interceptor reserves after expending significant quantities during clashes with Iran last year.
The ongoing wave of Iranian missile attacks has further stretched Israel’s long-range air defence systems, raising concerns about the sustainability of its defensive capabilities.
The shortage has been anticipated by Washington for some time. One US official said American authorities had been aware for months that Israel’s interceptor capacity was limited and that the strain was expected as hostilities continued.
Reports indicate that Iran has also modified some of its missiles by adding cluster munitions, a tactic that could complicate interception efforts and accelerate the depletion of defensive missiles.
Despite the situation facing Israel, US officials emphasized that American military stockpiles remain adequate. Washington maintains that it has sufficient interceptor systems and other assets to safeguard its bases, personnel, and strategic interests in the region.
However, it remains unclear whether the United States will transfer or sell additional interceptors to Israel. Such a move could place additional pressure on US defence inventories, particularly if the conflict becomes prolonged.
Missile interceptors form a critical layer of Israel’s air defence network against long-range ballistic threats.
While the country also relies on fighter aircraft and other defensive systems, interceptors are considered among the most effective tools for neutralizing incoming missiles before they reach populated areas or military sites.
Israel’s well-known Iron Dome system primarily focuses on countering short-range rockets and projectiles, whereas longer-range threats are typically handled by systems designed to intercept ballistic missiles at higher altitudes.
Earlier this month, US President Donald Trump said the United States possessed a “virtually unlimited” supply of munitions.
Nevertheless, defence analysts have long argued that American inventories are lower than what the military would ideally prefer for sustained conflict.
Research by the Center for Strategic and International Studies suggests that during a 12-day confrontation with Iran last June, the United States launched more than 150 THAAD interceptors—estimated to be roughly a quarter of the US inventory at the time.
Reports have also suggested that Patriot interceptor missiles worth about $2.4 billion were used during the first five days of the ongoing conflict.
In response to rising demand, the Pentagon earlier this year initiated efforts to significantly expand production of the THAAD missile defence system. Officials say the United States still maintains sufficient THAAD batteries, interceptor missiles, and combat aircraft to meet operational requirements.
Pentagon spokesperson Sean Parnell said the US Department of Defense currently possesses all necessary capabilities to carry out missions at the time and location determined by the president.
Meanwhile, the White House reiterated confidence in US military readiness. Officials argued that joint operations with Israel have significantly reduced the impact of Iranian attacks, noting sharp declines in drone and ballistic missile strikes since the escalation began.
Although President Trump has described the war as a short-term operation that could conclude soon, signals from Washington, Tel Aviv, and Tehran suggest preparations are underway for a potentially extended confrontation.
