The Biden administration is set to announce its final Ukraine Security Assistance Initiative (USAI) package in the coming days, utilizing the remaining funds allocated for new weapons procurement for Ukraine, according to multiple sources familiar with the matter, Reuters reported. The package, valued at approximately $1.2 billion, will reportedly include air defense interceptors and artillery munitions to bolster Ukraine's defensive capabilities against ongoing Russian aggression.

This USAI package marks the culmination of the Biden administration's military assistance to Ukraine under this program, as the U.S. approaches a critical transition in leadership. President-elect Donald Trump, set to take office on January 20, has publicly questioned the continuation of military aid to Ukraine, creating uncertainty about the future of U.S. involvement in the conflict. Trump has vowed to bring the war to an end within "24 hours" of his inauguration, though he has provided no details on how this would be achieved.

The USAI operates differently from presidential drawdown authority (PDA), under which military aid is drawn directly from existing U.S. stockpiles and can be deployed rapidly. In contrast, USAI packages rely on procurement from defense contractors, meaning that delivery of equipment and weapons often takes months or even years. To date, about half of the $61.4 billion in U.S. security assistance to Ukraine under President Biden has been allocated through the USAI.

The remaining $5.6 billion in PDA funds could provide another avenue for additional aid, but time is running out to allocate these resources before the new administration takes office. Analysts suggest that the Biden administration may prioritize expediting aid under PDA to ensure delivery before policy changes potentially disrupt future support.

Since Russia's invasion of Ukraine in February 2022, the United States has been the largest provider of aid to Kyiv, committing a total of $175 billion in assistance, including humanitarian, financial, and military support. The aid packages have been a cornerstone of the Biden administration's foreign policy, aiming to fortify Ukraine's resistance against Russian advances and protect European security.

The State Department and Pentagon have refrained from commenting on the forthcoming announcement, as is customary before official disclosures of security assistance packages. However, the anticipated contents of the package highlight the Biden administration's focus on sustaining Ukraine's air defense and artillery capabilities, crucial elements of its ongoing strategy to counter Russian missile strikes and ground offensives.
