The Pentagon has revealed that military aid the United States sent to Ukraine, including weapons and ammunition, was overestimated by at least $3 billion due to an accounting error. The Department of Defense inadvertently used the replacement cost rather than the net book value when assessing the equipment’s worth, leading to the overvaluation. The error does not appear to have impacted Ukraine’s support from the US. The Biden administration may delay requesting more aid from Congress due to the discrepancy. Republican lawmakers have expressed concern about the increased military aid to Ukraine, calling for greater oversight. The United States has sent more than $36.9 billion in aid to Ukraine since Russia invaded in February 2022.
