ABC News has obtained a letter sent by a top Ukrainian official to senior members of Congress, asking them to assist Ukraine's calls for additional air defense systems to counter the attack drones built and supplied by Iran to bolster Russia's war effort.
Russia has launched waves of deadly attacks in recent weeks, using Iranian-made drones that explode on impact to strike power plants, killing civilians and causing rolling blackouts, plunging millions of Ukrainian homes into darkness.
In the letter, the chairman of the Ukrainian parliament, Ruslan Stefanchuk, calls on the U.S. to provide Ukraine with highly mobile air defense systems known as C-RAMs, saying they would help protect "important objects, especially crucial power plants."
C-RAMs have a built-in radar to track incoming threats and a giant rapid-fire gun to shoot them down, with NATO saying the "most effective" systems are able to fire 4,500 rounds per minute.
