This article's lead section may be too short to adequately summarize the key points. Please consider expanding the lead to provide an accessible overview of all important aspects of the article. (November 2023)

On 24 February 2022, Russia invaded Ukraine, escalating the Russo-Ukrainian War that began in 2014 into the full-scale invasion and the biggest war in Europe since World War II. Twenty-one months later, on 20 November 2023, Ukraine had cumulatively received over $44 billion in materiel aid from the United States and over $35 billion from other allies^[1] on a month-to-month basis. The aid is logistical and is provided by drawdown of existing materiel that is then delivered to Ukraine. As this materiel is expended, the allied industrial base has been gradually drawn in to supply Ukraine but had not been fully engaged^[a] as of November 2023.^[b] Since January 2022, mostly Western nations have pledged more than $380 billion in aid to Ukraine, including nearly $118 billion in direct military aid to Ukraine from individual countries.^[2]
