The ongoing wars in the Middle East and Ukraine have depleted US stockpiles of missile interceptors. The Pentagon has just a quarter of the Patriot missiles it needs.

According to the Guardian, “The United States only has about 25% of the Patriot missile interceptors it needs for all of the Pentagon’s military plans after burning through stockpiles in the Middle East in recent months, an alarming depletion that led to the Trump administration freezing the latest transfer of munitions to Ukraine.”

US weapons manufacturers can only produce approximately 500 Patriot missiles per year. The US used dozens of interceptors to defend Israel from Iranian retaliatory attacks last month. Additionally, the Pentagon engaged in its largest Patriot battle in history to repel a symbolic Iranian missile attack on the US airbase in Qatar.

The US stockpile of air and missile defenses has been drained to aid Ukraine during the war with Russia. Missile interceptors are in short supply in the West. In May, Secretary of State and National Security Advisor Marco Rubio told Congress that “The Ukrainians asked for air defense systems – Patriot systems, which, frankly, we don’t have.”

It is unclear if Trump reversed the Pentagon order to halt some arms transfers to Ukraine, including Patriot Missiles. During Monday’s dinner with Israeli Prime Minister Benjamin Netanyahu, Trump told reporters that he would “send some more weapons” to Ukraine.

Patriot systems have been a crucial part of Ukraine’s air defenses. However, Russia has developed missiles to counter Patriot interceptors with increasing effectiveness.
