The White House on May 31 announced another aid package for Ukraine that includes up to $300 million worth of air-defense systems, ammunition, and other defense equipment. The security assistance package represents the 39th drawdown of equipment from the Defense Department inventories, the Pentagon said. The package includes Patriot air-defense batteries, Stinger antiaircraft systems, tank ammunition, and other equipment. In total, the United States has committed more than $37.6 billion in security assistance to Ukraine since Russia launched its invasion in February 2022.
