Document Introduction

This report is the quarterly submission to Congress by the Special Inspector General of the United States Congress, as mandated by Section 1250B of the National Defense Authorization Act for Fiscal Year 2024 and the Inspector General Act (5 U.S.C. 419), concerning Operation Atlantic Resolve and U.S. government activities related to Ukraine. It covers the period from January 1 to March 31, 2025. The report aims to comprehensively aggregate, assess, and oversee U.S. military, economic, and humanitarian assistance to Ukraine, related diplomatic and security operations, and the oversight work of various federal agencies, particularly the Department of Defense, the Department of State, and the U.S. Agency for International Development.

The report begins with an overview of the total assistance scale since February 2022: Congress has appropriated or allocated 184.81 billion dollars for related operations. As of the end of the quarter, 34.26 billion dollars remained available for use. This quarter saw significant adjustments in U.S. policy. President Trump signed an executive order on January 20, imposing a 90-day pause and comprehensive review on U.S. foreign assistance, leading to the suspension of almost all Ukraine assistance projects funded by the State Department and USAID, although some life-saving humanitarian projects received exemptions. Furthermore, the U.S. announced its withdrawal from international institutions such as the World Health Organization and the International Center for the Prosecution of the Crime of Aggression against Ukraine, altering some aid delivery channels. Regarding military assistance, a brief suspension occurred from March 3 to 11, which was later resumed following a meeting between U.S. and Ukrainian delegations in Jeddah, Saudi Arabia.

The core analysis of the report revolves around security, diplomacy, and the battlefield situation. On the security front, the primary objective of Operation Atlantic Resolve is to deter Russia by enhancing the presence on NATO's eastern flank, providing security assistance, and conducting joint training exercises. The report details the various mechanisms for U.S. military assistance delivery to Ukraine, fund allocation, and end-use monitoring. It notes that Ukraine's defense industry, particularly in the drone sector, has demonstrated excellent performance in iterative innovation. Diplomatically, the U.S. actively mediated for a ceasefire but achieved limited success in brokering a comprehensive one. Only a limited verbal ceasefire agreement regarding attacks on energy infrastructure was reached, and both sides soon accused each other of violations. On the battlefield, missile and drone strikes continued to dominate the conflict, with both sides targeting critical energy and defense infrastructure. Both Ukrainian and Russian forces face severe personnel shortages. Russian forces have suffered heavy casualties, while Ukrainian forces grapple with challenges including casualties, desertion, refusal to fight, and insufficient training.

In the funding and oversight section, the report provides a detailed audit of U.S. assistance funds to Ukraine to date, broken down by agency, program, and category (security, governance and development, humanitarian, institutional operations), and tracks the status of appropriations, obligations, and disbursements. The report highlights the work of oversight bodies (the Department of Defense, Department of State, USAID Offices of Inspector General, and the Government Accountability Office) in identifying waste, fraud, and abuse. It also lists summaries of 25 relevant oversight reports completed this quarter, along with ongoing and planned oversight projects.

This report is compiled based on data collected from relevant federal agencies, open-source information, and the independent investigations, audits, and evaluations conducted by the various Inspector General offices. It aims to provide Congress and the American public with a high-level, comprehensive assessment of the transparency and accountability of U.S. operations concerning Ukraine.
