Since the onset of Russia's military operation in Ukraine, the US Congress has allocated over $182 billion in aid to Ukraine, according to a Pentagon Inspector General report.

The funds, totaling $182.99 billion, have been directed toward Operation Atlantic Resolve (OAR) and the broader Ukraine response, with $131.36 billion designated for security-related support and $43.84 billion for governance and development efforts.

These allocations have been managed through various US federal agencies, including the Pentagon, the State Department, and USAID.

In response to these arms supplies, Russian Foreign Minister Sergey Lavrov warned that any shipments containing weapons for Ukraine would be considered legitimate targets.

US weapons shortage limits Ukraine aid despite available funds

Earlier, in September, CNN reported that a reduction in US weapons stockpiles has led to more modest aid packages being sent to Ukraine in recent months, as confirmed by several US officials.

"We have $5.9 billion left in Ukraine Presidential Drawdown Authority; all but $100 million of which will expire at the end of the fiscal year. DOD is working with Congress to seek an extension of PDA authorities beyond the fiscal year's end, " a Pentagon statement read. 

Despite the Biden administration having nearly $6 billion available under the Presidential Drawdown Authority (PDA) to assist Ukraine, it faces constraints due to the lack of available weapons in storage.

The report further explains that the PDA is at risk of expiring on September 30 unless Congress acts to extend the deadline, allowing more time to utilize the remaining funds.

A contributing factor to the limited assistance provided to Ukraine includes the US' cautious approach not to compromise its military readiness and a policy against overwhelming Ukraine with more weapons than it can effectively manage and distribute.
