Low-cost drones with reduced radar cross-sections are increasingly challenging advanced air defense systems, highlighting a major shift in modern warfare dynamics. Reports suggest such drones can evade conventional detection while imposing heavy financial strain due to the imbalance between inexpensive offensive platforms and costly defensive interceptors. In the ongoing Iran-Israel conflict, this trend is becoming more evident, with strategic targets like airports—critical for both civilian travel and military logistics—facing new vulnerabilities. This evolving threat landscape raises key questions about the future of air defense, cost efficiency, and battlefield strategy.
