Russia upgrades drones for Ukraine attacks

Russia launched its largest drone attack on Ukraine, deploying 472 one-way attack drones on June 1, overwhelming Ukrainian defenses. This marks a significant escalation in the ongoing conflict. Moscow has enhanced its drones with SIM cards for data transmission and radar-absorbing coatings, alongside incendiary and fragmentation warheads. These upgrades, coupled with decoy drones, aim to increase the effectiveness and survivability of the attacks. The attacks highlight Russia's strategy of exhausting Ukrainian air defenses through mass drone deployments, while Ukraine also employs its own drone strikes. This ongoing drone war presents complex challenges for both sides.
