Recent months have seen a reduction in the size of US military aid packages for Ukraine, primarily due to the diminishing stockpiles of weapons and equipment that the Pentagon is prepared to send from its own reserves. This change arises from concerns regarding the potential effects on US military readiness, as domestic arms manufacturers strive to meet the substantial demand generated by the ongoing conflict with Russia.

Despite having $6 billion in available funds to support Ukraine’s military needs, the Pentagon is currently unable to provide additional inventory more than two years into the conflict, as reported by two US officials to CNN.

One official noted, “The situation revolves around our existing stockpiles, the specific requests from Ukraine, and our ability to fulfill those requests without compromising our military readiness.”

According to Maj. Gen. Pat Ryder, the Pentagon press secretary, the Pentagon has requested Congress for an extension to utilize these funds before they expire at the end of September. This marks a significant shift from last winter, when the administration was actively seeking more funding to bolster Ukraine’s defense against Russia’s aggression.

The official also highlighted that replenishing stockpiles is a critical concern. The US is increasing production of essential items, including 155 mm ammunition and Patriot missile systems, to support both Ukraine and replenish its own inventories. However, this is a lengthy process that will not quickly satisfy the rising demand.

Prior to the conflict in Ukraine, the US produced around 15,000 155 mm artillery shells monthly. With the establishment of new factories and production lines, this output has increased to 40,000 shells per month. Nevertheless, it will take over a year for the Pentagon to reach its target of producing 100,000 shells each month. While the ramp-up in production is progressing as planned, it requires years of investment in new facilities, expanded manufacturing capabilities, and Congressional support for funding.

CNN has reached out to the National Security Council for further comments.

According to Pr., Ukraine is experiencing the repercussions of these inventory shortages.
