Counter-Drone Layered Defense

Counter-drone layered defense is the use of multiple defensive methods, ranges, and cost tiers against drones rather than relying on one expensive interceptor or one electronic countermeasure. How low-cost drones are used in modern military strikes adds the concept through Stacey Pettijohn’s point that there is no stable endpoint where defenders can declare all drone threats solved.

The source describes a moving contest. Cheap commercial drones may be jammed by disrupting control links, but attackers can adapt with better antennas or fiber optic control. Armed one-way drones and decoys then require classification, short-range defense, and cost discipline so defenders do not waste high-end systems on low-end targets.

Key Claims

• Jamming can work against some commercial drones, but attackers can adapt the control link.
• Physical interception, electronic warfare, sensors, classification, and command decisions need to operate as layers.
• Short-range, lower-cost defenses are important because expensive strategic air-defense missiles are often mismatched against cheap drones.
• Layered defense must expect continuing attacker adaptation rather than a final solved state.
