The United States has been a major supporter of Ukraine’s security since Russia’s renewed and expanded invasion of Ukraine on February 24, 2022. From 2014, when Russia first invaded Ukraine, to January 19, 2023, the United States has provided around $29.5 billion in security assistance to aid Ukraine in maintaining its territorial integrity, securing its borders and improving its compatibility with NATO. The Biden Administration alone has committed over $26.7 billion in security assistance since the start of the 2022 war. The funding for the security assistance packages in FY2022 and FY2023 primarily comes from $48.7 billion in supplementary appropriations. This includes $25.93 billion to refill the Department of Defense equipment stocks sent to Ukraine through presidential drawdown authority, $18 billion for the Ukraine Security Assistance Initiative (USAI; P.L. 114-92, §1250) and $4.73 billion in Foreign Military Financing (FMF; 22 U.S.C. §2763) for Ukraine and countries affected by the situation in Ukraine.
