What is Security Assistance?

 

U.S. security assistance to Ukraine and European partners provides essential military resources, funding, and training in support of Operation Atlantic Resolve through multiple established programs and mechanisms, including the Ukraine Security Assistance Initiative (USAI), replenishment of stocks transferred under Presidential Drawdown Authority (PDA), Foreign Military Financing (FMF), and International Military Education and Training. To protect U.S. commercial and military aviation, State’s Bureau of Political-Military Affairs leads U.S. cooperation with France, Germany, the United Kingdom, the European Union, and Ukraine to mitigate the risk of illicit diversion of portable advanced conventional weapons in Eastern Europe. In addition, the United States supports military deployments and training activities throughout the U.S. European Command (USEUCOM) area of responsibility.

What's New in the Latest Report?

This Quarter's Security Highlights: 

In July, the United States and NATO developed a new mechanism to supply the UAF with weapons, ammunition, and other materiel: the Prioritized Ukraine Requirements List (PURL) initiative. Through the PURL initiative, NATO allies and partners voluntarily contribute funds to a NATO-managed holding account that is then used to pay for U.S. defense articles. State reported that since the PURL initiative’s inception, more than 20 NATO allies and two NATO partners—Australia and New Zealand—have contributed or pledged more than $4 billion. 

Since July, the United States announced and implemented its strategic intention to urge European allies to assume a greater share of responsibility for the personnel, materiel, and funds that account for NATO’s collective defense and European security. 

On August 4, NATO announced that the Netherlands agreed to fund the first PURL package. On September 17, President Zelenskyy told reporters that Ukraine’s partners had purchased more than $2 billion in weapons and materiel from the United States for the UAF through the PURL initiative. 

In September, the DoW announced that it would begin phasing out security assistance for Eastern European partners and allies along Russia’s border. Specifically, the DoW will not request additional funding that is used to train and equip the militaries of partner nations, according to media reporting. Funds already approved for the program will remain available through September 2026.

Security Topics

  • $7.2  billion in appropriations for the U.S. Ukraine response remains available for obligation, most of which will replenish DoW stocks. 
  • The DoW has $5.5  billion remaining in authority to transfer weapons, ammunition, and equipment from DoW stocks to Ukraine.

Oversight Highlights

Special IG and partner agencies issued 19 reports related to OAR from July 1 to December 31, 2025, including:

Equipment

The United States continued to collaborate with coalition partners to provide defense articles and materiel requested by the Ukrainian government. From February 2022 through December 2025, the United States had committed more than $66.1 billion in defense articles and services to Ukraine through PDA, USAI, and FMF, while allies and partners have committed approximately $120.0 billion. This assistance includes armored vehicles, air defense systems and interceptors, ammunition, and other capabilities. FMF support to Ukraine in 2024 has included air defense, armored vehicles, anti-armor capabilities and munitions.

Oversight Highlight: End-Use Monitoring

Federal law requires end-use monitoring (EUM) of certain transfers of defense equipment and services to foreign entities to ensure that the items are being used in accordance with the terms and conditions of the transfer agreement and applicable Federal law. Certain defense items are subject to enhanced EUM (EEUM) if they incorporate sensitive technology; are particularly vulnerable to diversion or other misuse; or the diversion or other misuse of these items could have significant consequences for U.S. national security.
