The United States said it would give Ukraine a new military aid package worth $200 million as President Volodymyr Zelenskiy traveled to NATO’s headquarters in Belgium to press for more support for his war-ravaged country ahead of the onset of the cold season.

“I’m proud that the United States will announce its latest security assistance package for Ukraine, valued at $200 million,” U.S. Defense Secretary Lloyd Austin said alongside Zelenskiy at the opening of a meeting of the U.S.-led Ukraine Defense Contact Group, also known as the Ramstein format, which consists of some 50 countries that back Kyiv in its war against Russia.

Austin said the new package will consist of air-defense, rocket, and artillery ammunition as well as anti-tank systems, among other things, adding that Washington “will stand with Ukraine for as long as it takes.”

Danish Defense Minister Troels Lund Poulsen told the Defense Contact Group that his country will deliver the first U.S.-made F-16 warplanes to Ukraine in the spring of next year. In August, Zelenskiy said Denmark had approved sending 19 of the advanced warplanes to Ukraine.

Prime Minister Alexander De Croo said after meeting with Zelenskiy that Belgium will send F-16s to Ukraine from 2025 and provide their maintenance.
