The aid includes counter-artillery radars, air surveillance systems, other tactical equipment, military medical treatment, cyber defenses, “strategic communications,” according to a Thursday release by the Pentagon. Intended to help Ukraine fight the Russia-backed forces that have occupied part of the country’s eastern region since 2014, the aid aims to “enhance Ukraine’s defensive lethal capabilities and situational awareness in the maritime domain” and “counter Russian cyber offensive operations and misinformation.”

Past U.S. aid to Ukraine, which totals about $1.5 billion, has included: Javelin anti-tank missiles, retired Coast Guard cutters, unarmed drones, Harris radios, armored Humvees, and communications equipment. The U.S. has also helped to train Ukrainian special forces.

The release said the new aid re-affirms the “long-standing defense relationship between the United States and Ukraine – a critical partner on the front line of strategic competition with Russia. The United States remains steadfast in its support for Ukraine’s sovereignty and territorial integrity within its internationally recognized borders.”
