KHARKIV REGION, UKRAINE - APRIL 7: The launch of the new 'Marsianin' combat drone by servicemen from the «Taifun» unmanned systems unit on April 7, 2026 in Kharkiv region, Ukraine. After years of developing systems and know-how to fend off Russia's drone attacks, Ukraine is now offering its hard-won expertise and counter-drone technology to other countries. In recent weeks, Ukrainian President Volodymyr Zelensky has been visiting Gulf states who are confronting a wave of relatively cheap kamikaze drones launched by Iran as it lashes out neighboring countries after the joint U.S.-Israeli attack.
