Range doubled: Ukraine uses a simple trick to combat Russia's superior power in the drone war. “We are currently in a production war,” a senior NATO official told CNN.

Ukraine is threatened with a massive shortage of ammunition because the NATO countries have so far fallen far short of their arms delivery commitments. The outcome in Ukraine depends on how prepared each side is to wage this war, a senior European official said. The U.S. plans to produce 100,000 artillery shells per month and send them to Ukraine by the end of 2025 - which currently corresponds to less than half of Russia's monthly production.
