The US is running low on some high-end weapons systems and ammunition available to transfer to Ukraine, three US officials with direct knowledge tell CNN.
The strain on weapons stockpiles – and the ability of the US industrial base to keep up with demand – is one of the key challenges facing the Biden administration as the US continues to send billions of dollars of weapons to Ukraine to support its fight against Russia. One of the officials said the stockpiles of certain systems are “dwindling” after nearly nine months of sending supplies to Kyiv during the high-intensity war, as there’s “finite amount” of excess stocks which the US has available to send.
Among the weapons systems where there’s particular concern about US stockpiles meeting Ukrainian demands are 155mm artillery ammunition and Stinger anti-aircraft shoulder-fired missiles, the sources said.
Some sources also raised concerns about US production of additional weapons systems, including HARMs anti-radiation missiles, GMLRS surface-to-surface missiles and the portable Javelin anti-tank missiles – although the US has moved to ramp up production for those and other systems.
For the first time in two decades, the US is not directly involved in a conflict after withdrawing from Afghanistan and transitioning to an advisory role in Iraq. Without the need to produce weapons and ammunition for a war, the US has not manufactured the quantities of material needed to sustain an enduring, high-intensity conflict.
Multiple officials underscored that the US would never put at risk its own readiness, and every shipment is measured against its impact on US strategic reserves and war plans.
