UPDATE: Ukrainian intelligence used naval drone to launch a smaller attack drone, which then took out one of Russia’s S400 defense system. 🇺🇦🇷🇺 The S-400 is one of Russia’s most prized air defense systems, built to shoot down aircraft, drones, and missiles at long range. The cost gap is staggering. A single S-400 launcher and its support systems can cost billions of dollars. The drones used to destroy it likely cost only in thousands. What is genuinely new is the method. Ukraine used a naval drone, built for sea warfare, as a launch platform to carry smaller FPV drones against land targets.(Donald J Trump Posts TruthSocial)
