intelligence officers reportedly assisted in advancing Ukraine's drone capabilities, helping to design a new generation of drones intended to revolutionize modern warfare.While much of the U.S. aid for Ukraine has been publicly disclosed — covering missiles, air defense systems, tanks, and training — support for the drone sector has largely remained secret. The declassified data reveals that the U.S. allocated funds for drone manufacturing and facilitated partnerships between U.S. tech companies and Ukrainian drone producers. These efforts intensified during preparations for Ukraine's 2023 counteroffensive, which struggled to achieve significant territorial gains, reportedly due to Russia's extensive drone use. In response, the U.S. accelerated aid to Ukraine's drone sector.Officials reportedly believe this investment has made Ukrainian drones more effective and deadly. Ukrainian maritime drones, credited with destroying 25% of Russia's Black Sea Fleet, and aerial drones deployed on the front lines have slowed Russian advances in eastern Ukraine.By the end of 2024, Ukraine had delivered over 200,000 domestically produced drones to frontline units, Defense Minister Rustem Umerov said in December.
