Inside Ukraine's Secret Sea Drone Arsenal: A Game-Changer in the Black Sea

Ukraine has granted CNN exclusive access to its secret military base where sea drones are tested. These naval drones, never before shown to journalists, are proving to be a vital tool for Ukraine in countering Russian forces in the Black Sea and Crimea. Weighing up to 1,000 kilograms with an explosive payload of up to 300 kilograms, these sea drones have been involved in recent attacks on Russian assets, including the Kerch Bridge. The drones' speed and difficulty in detection make them a formidable threat, and Ukraine claims that it will take Russia years to effectively counter this technology.
