I was able to find the following information on the Internet about the assistance provided to Ukraine in connection with the military attack on it by Russia:
The Washington Post wrote that since the beginning of the full-scale Russian invasion of Ukraine, the United States has allocated more than $66 billion in total aid to Ukraine. This is more than the US provides in aid to any other country. More than $43 billion was allocated to Kyiv as military aid, accounting for 65% of the total.
Washington provided $23.5 billion directly for weapons and equipment, $18 billion for other assistance (training, consulting, logistics and equipment), and $1.5 billion for grants and loans to other countries for the purchase of weapons and equipment. Another $20.5 billion was allocated to support Ukraine’s budget, and more than $2.6 billion was allocated to support displaced persons, refugees and other vulnerable populations in the country and abroad.

American Defense Secretary Austin, during his current visit to Ukraine, said that the United States provided assistance to Ukraine in the amount of 42 billion, and the remaining 50 US allies allocated 36 billion. That is, total assistance to Ukraine amounted to $78 billion.

Even the Russian Gazeta.RU, citing Pentagon information, reported that from February 24, 2022 to April 19, 2023, the volume of Washington’s military assistance to Kiev reached $35.4 billion. Moreover, since the beginning of Joe Biden’s presidency (2020), Ukraine has been allocated from the US budget of $36.1 billion in aid.
