美国承认：伊朗无人机攻势比想象中难对付

Core Viewpoint - The U.S. military faces significant challenges in intercepting Iran's "Shahed" one-way attack drones, which are low-cost yet highly destructive, likened to an "aerial AK-47" [1][4] Group 1: Military Challenges - U.S. Defense Secretary and Joint Chiefs of Staff Chairman acknowledged that Iran's drones are harder to counter than expected due to their low flight altitude and slower speed, making them easier to evade interception compared to ballistic missiles [1] - Since the U.S. and Israel initiated military strikes against Iran on February 28, Iran has launched over 2,000 one-way attack drones, with some successfully hitting targets despite the U.S. and Israeli defense systems valued in the billions [1] Group 2: Cost Implications - Military experts highlight the unsustainable cost of intercepting drones, with estimates suggesting that the cost of intercepting a €30,000 drone could reach up to $1 million for a single missile, leading to a cost ratio of 10:1 to as high as 70:1 [4] - The continuous use of drones could rapidly deplete the stockpile of intercept missiles, increasing pressure on defense budgets and resources, especially as high-end systems are being used against drones instead of their intended targets [7] Group 3: Strategic Considerations - The conflict is characterized as a war of attrition, where the cheapest weapons, such as drones, may prove to be the most destructive, aiming to exhaust air defense systems and increase economic costs [7] - U.S. officials express concerns about the finite supply of ammunition, with questions raised about how to replenish air defense munitions in the face of ongoing drone attacks [7]
