Department of Defense Supplemental
Funding for Ukraine: A Summary
Updated April 29, 2024
To date, Congress has appropriated $174.2 billion in emergency supplemental funding in response to
Russia’s 2022 renewed invasion of Ukraine. Of this amount, $110.7 billion (64%) was provided for the
U.S. Department of Defense (DOD) and certain other defense-related activities.
The Biden Administration had requested supplemental funding to provide military equipment and
operational support to Ukraine, replace items transferred from department stocks, deploy additional U.S.
military personnel to Europe, and carry out other activities. The Administration submitted such requests
on March 2, 2022 (for FY2022); April 28, 2022 (for FY2022); September 2, 2022 (for FY2023);
November 15, 2022 (for FY2023); August 10, 2023 (for the first quarter of FY2024); and October 20,
2023 (for FY2024).
This Insight summarizes such funding by appropriations act and by major DOD appropriation category, or
title. It also provides information about related funding transfers and reprogramming actions, Office of
Inspector General (OIG) reports, and potential issues for Congress on this topic.

DOD Funding by Major Appropriation Title
Table 2 summarizes FY2022, FY2023, and FY2024 emergency funding provided to DOD in response to
the situation in Ukraine, by major appropriation title (i.e., operation and maintenance, or O&M;
procurement; research, development, test, and evaluation, or RDT&E; military personnel, or MILPERS).
While Congress provided the vast majority of the funding—$89.5 billion (81%)—for the department’s
O&M accounts, it included provisions to allow for most of such O&M funding to be used for replacing
items transferred from DOD stocks and procuring newly manufactured weapons and equipment for
Ukraine under the Ukraine Security Assistance Initiative (USAI).
The Administration had requested certain other O&M funding “for operational support such as
intelligence analysis, flying hours, maintenance, and weapon system sustainment; and other unit support
costs,” including classified programs; procurement funding for “cybersecurity and weapon systems
upgrades required for the European theater of operations,” including classified programs; RDT&E
funding for “artificial intelligence-algorithm development, cybersecurity, and other information
technology requirements,” including classified programs; and MILPERS funding “to support personnel
who are currently deployed or preparing for deployments to and within the European theater of
operations, including special pays such as family separation allowance.”

O&M Funding for Replacement and USAI Activities
To date, of the $89.5 billion in emergency O&M funding, Congress provided authority for DOD to
transfer up to $39.3 billion (44%) between certain accounts to replace DOD stocks of weapons,
munitions, and other equipment, as well as to reimburse the department for services, military education,
and training provided to Ukraine or foreign countries that have supported Ukraine. In addition, of the
same O&M funding, Congress has provided $31.8 billion (36%) for USAI. See Table 3.

Selected DOD Resources
Ukraine-Related Reprogramming Actions
The DOD Comptroller maintains a website of information about funding transfers and reprogramming
actions taken in support of Ukraine. A transfer involves shifting funds from one appropriation account to
another, while a reprogramming involves shifting funds within the same account. To date, the transactions
have involved various funding reallocations in support of Ukraine, such as the procurement of Armored
Multi-Purpose Vehicles (AMPVs) to replace M113 tracked personnel carriers transferred to Ukraine.

DOD Fact Sheets and Infographics
DOD has published and periodically updates fact sheets and infographics on U.S. security assistance
provided to Ukraine. For a list of U.S. military equipment provided to Ukraine to date, see the
department’s April 24, 2024, fact sheet on U.S. security assistance to Ukraine. For a list of DOD
contracting actions related to Ukraine to date, including a map totaling the dollar-amount of such actions
to date by state, see the department’s January 15, 2024, infographic on U.S. security assistance to
Ukraine.
DOD Inspector General Reports
The DOD Office of Inspector General (OIG) maintains a website of information on its oversight work
related to Ukraine. The site is organized by oversight updates, ongoing work, and completed work. The
completed work has included multiple reports on DOD’s response to the situation in Ukraine, including
the department’s use of supplemental funds (e.g., DODIG-2024-069), end-use monitoring of equipment
provided to Ukrainian forces (e.g., DODIG-2023-090), plans to sustain Patriot air defense systems and
other weapons systems transferred to Ukraine (e.g., DODIG-2024-056), and other topics.
Potential Issues for Congress
Some Members of Congress have expressed interest in the relationship between funding and authorities
related to two broad types of activities associated with arming Ukrainian forces: 1) transferring equipment
from DOD stocks using Presidential Drawdown Authority (PDA; 22 U.S.C. §2318); and 2) replacing
those items using funding and transfer authorities provided in supplemental appropriations acts. Prior to
the enactment of FY2024 emergency supplemental funding for Ukraine, a DOD official stated the
department slowed drawdowns under PDA due to a lack of available replacement funding. In February
2024, Deputy Pentagon Press Secretary Sabrina Singh said the department was reluctant to incur risk
associated with using the remaining $4 billion balance of PDA while facing a shortfall of replacement
funding (later reported at $10 billion). Potential oversight questions on this topic include:
• Why would a limitation or absence of replacement funding prevent DOD from fully
utilizing PDA? How might using PDA prior to the provision of replacement funding
affect the department’s assessments of risk related to weapons and equipment
inventories?
• Given the disparity in the balance of PDA and shortfall of replacement funding in
February-March 2024, how much additional funding would be required to replace items
transferred from DOD stocks to Ukraine?
• How much emergency supplemental funding would be required to respond to the
situation in Ukraine in FY2025 and future years? How might evolving battlefield
conditions and/or potential discussions to negotiate an end to the conflict affect DOD
resourcing for related activities?
