Russia’s highly-touted S-400 air defense system is under intense scrutiny after a massive Ukrainian drone strike reportedly destroyed critical assets, including Russian bombers. On June 1, 2025, over 117 low-flying drones bypassed radar detection and targeted key military sites. Despite its reputation, the S-400 struggled to intercept these cheap, agile UAVs. Ukraine’s coordinated swarm attacks, use of jammers, decoys, and anti-radar missiles highlight growing vulnerabilities in legacy defense systems like the S-400—designed for jets and missiles, not modern drone warfare. br br #Ukraine #Russia #S400 #DroneStrike #AirDefense #UAV #DroneWarfare #UkraineWar #S400Failure #MilitaryNews #Zelensky #DefenseNews #BreakingNews #RussiaUkraineWar #Drones #ATACMS #HIMARS #MissileDefense #MilitaryTech #Kremlin #RussiaMilitary #GeoPolitics #UkrainianDrones #DroneSwarm #WarUpdate #Putin #NATO #ModernWarfare #RussianBombers #BattlefieldInnovation #117Dronesbr br ~ED.102~HT.
