The US Senate has passed $95 billion (£76 billion) in mainly military aid to Ukraine, Israel and Taiwan.
The final vote on April 23 was 79 to 18 and came after months of delays and debate over how involved the US should be in foreign conflicts.
President Joe Biden confirmed that he will sign the bill on Wednesday and start the process of sending weapons to Ukraine, which has been struggling to hold its frontlines against Russia.
"Tonight, a bipartisan majority in the Senate joined the House to answer history's call at this critical inflection point," Biden said.
The legislation also provides for $26 billion in wartime assistance to Israel and humanitarian relief to citizens of Gaza, as well as $8 billion to counter Chinese threats in Taiwan and the Indo-Pacific.
In an interview with the Associated Press shortly before the vote, Senate Majority Leader Chuck Schumer said that if Congress hadn't passed the aid: "America would have paid a price economically, politically, militarily."
"Very few things we have done have risen to this level of historic importance," he said.
On the Senate floor, Schumer said the Senate was sending a message to US allies: "We will stand with you."
Schumer and Senate Republican Leader Mitch McConnell made passing the legislation a top priority, arguing there could be dire consequences for the United States and many of its global allies if Russian President Vladimir Putin's aggression was left unchecked.
