U.S. officials have raised concerns that Israel is “running critically low on ballistic missile interceptors” as it faces ongoing attacks from Iran.

According to these officials, Israel entered the current conflict with an already depleted interceptor stock following the 12 Days War with Iran last June.

Israel’s long-range defense capabilities are under significant pressure, and with Iran reportedly preparing to deploy cluster missiles, the situation could become more challenging, as reported by CNN.

An American official disclosed to Semafor that the U.S. has been aware of this low capacity for some time, stating, “It’s something we expected and anticipated.”

Despite the situation, U.S. stockpiles remain sufficient, the official assured, addressing concerns that a prolonged conflict with Iran could impact American reserves.

It remains uncertain whether the U.S. will decide to sell or share its interceptor stockpiles with Israel, a move that could affect its own supplies. Historically, the U.S. has provided Israel with interceptor missiles as part of military aid.

Israel is ‘coming up with solutions’ for their missile shortage, the US official said.

There are other ways to defend against Iranian missiles, like the use of fighter jets, but interceptors are among the most reliable weapons against these kinds of long-range strikes.

US stockpiles of interceptors are ‘virtually unlimited’ claimed president Donald Trump, but the veracity of this declaration has been called into question by analysts who have long said that supplies are lower than the military would like, the New York Times reported.

The US fired over 150 THAAD interceptors during the 12 Days War in June 2025 – around a quarter of its inventory at the time, the Centre for Strategic and International Studies found.

In the first five days of the current Iran War, the US reportedly already fired $2.4 billion worth of Patriot interceptors.

In January, the Pentagon began substantially increasing its production of THAAD missiles, Lockheed Martin announced, as the US Official said that they had plenty of them as well as fighter jets and mid-level interceptors.

Chief Pentagon spokesman Sean Parnell said that the US has ‘everything it needs to execute any mission at the time and place of’ Trump’s choosing.

White House press secretary Karoline Leavitt assured that US stockpiles were ‘more than enough’ to defeat Iran ‘and beyond’. She said the president was making sure to keep ‘strengthening’ the Armed Forces, calling on defence contractors to quickly build more US-made weapons.

Iranian drone attacks are down 95 per cent and ballistic missile attacks are down 90 per cent, Ms Leavitt claimed, praising US-Israeli combat.

Trump sold 12,000 ‘BLU-110A/B general purpose, 1,000-pound bomb bodies’ to Israel last week. He bypassed Congress on this by citing the ’emergency’ Israel and the US face in the Middle East.

The president has said the war should end ‘soon’ but added that both the US and Israel are prepared to fight for ‘as long as necessary’ for their aims to be reached.

Meanwhile, Iran told CNN last week that the country sees no option for diplomacy now and also said it was digging in for a long fight.

Defence Secretary Pete Hegseth said Iran’s ‘entire ballistic missile production capacity’ has been ‘functionally defeated.’

However, on Friday several sites in Israel were struck by Iranian cluster bombs, but no casualties were reported.
