The Pentagon has found $2 billion worth of additional errors in its calculations for ammunition, missiles, and other equipment sent to Ukraine, a U.S. government report revealed on July 25. The Government Accountability Office report showed that the U.S. Department of Defense has faced challenges in valuing defense articles sent to Ukraine due to unclear accounting definitions. The Pentagon said in 2023 that "replacement value" had been used instead of "depreciated value" to tabulate the billions in matériel sent to Ukraine. That correction uncovered a $6.2 billion error, and the Pentagon now says $2 billion more in overstatements have been found. As a result, an additional $2 billion worth of arms can be sent to Ukraine to cover the amount of aid approved by the Biden administration.
