Moscow renewed its aerial assaults on Ukraine's national power grid in the spring, causing sweeping blackouts. Zelenskyy has said his country needs at least seven additional Patriot systems to protect itself.

Ukraine received the third Patriot system after pleas for equipment to guard against Russian air strikes.

“I set a task for our team to double our defense capabilities this summer, primarily Patriot and others,” Zelenskyy told regional leaders, referring also to U.S. Hawk and German Iris systems.

"And now we are starting to see results."

In his comments, posted on his Telegram channel, Zelenskyy said Ukraine had also received on Friday “additional support,” from the United States, but gave no details.

Earlier, in his nightly address, he also thanked Germany for providing the third Patriot system.

German Ambassador to Ukraine Martin Jaeger said on X that the newly supplied system will further protect civilians and critical infrastructure.

“It will enhance the protection of the country's population and infrastructure from airplanes, drones, and missiles,” he said.“In recent months, the Ukrainian crew has successfully completed appropriate training in Germany.
