The Biden administration is set to unveil its final Ukraine Security Assistance Initiative package in the coming days, utilizing the last of the allocated funds for new weapon purchases for Ukraine, as reported by two sources with knowledge of the situation. This package is expected to include air defense interceptors and artillery munitions, although the specific details will be disclosed upon the announcement. The total value of the package is estimated to be around $1.2 billion, according to the sources.

Under the USAI framework, military equipment is acquired from the defense industry or allied partners instead of being sourced from U.S. military stockpiles, which can result in delays of months or even years before the equipment reaches the battlefield. This package may represent one of the final measures the United States takes to offer direct military support to Ukraine, particularly as Kyiv prepares for the potential return of President-elect Donald Trump, who has expressed skepticism about military aid and has pledged to resolve the Ukraine conflict within 24 hours of assuming office on January 20.

Since Russia‘s invasion of Ukraine in February 2022, the United States has pledged $175 billion in aid, which includes approximately $61.4 billion designated for security assistance. About half of this security assistance has been provided through the USAI program, while the remainder has been allocated from existing military stockpiles via presidential drawdown authority. Currently, there is $5.6 billion left under the presidential drawdown authority.

The State Department and the Pentagon have refrained from commenting on the forthcoming announcement, stating that they do not discuss security assistance packages prior to their official disclosure. The USAI program has significantly benefited U.S. defense contractors, enabling them to secure orders for newly produced weapons and create new revenue opportunities.

A notable example is the L3Harris Technologies VAMPIRE system. This Vehicle-Agnostic Modular Palletized ISR Rocket Equipment counter-drone system received its inaugural USAI-funded order in August 2022. L3Harris successfully delivered its first four units within a year and has experienced heightened interest in the system, leading to multiple subsequent orders through the USAI program.

As the Biden administration gears up to announce the details of the final USAI package, uncertainties linger regarding the future of U.S. support for its ally without dedicated USAI funding. During his campaign, Trump frequently questioned the extent of U.S. involvement in the conflict, advocating for European allies to shoulder a greater share of the financial responsibility.

Some of his Republican colleagues, who will take control of both the House of Representatives and the Senate next month, have also shown a more cautious approach toward aid to Kyiv. This shift in perspective—despite previous strong bipartisan support in Congress for ongoing or increased assistance to Ukraine—has raised alarms among Ukraine’s advocates in Washington about the potential direction of U.S. support under a Trump administration.
