Countermeasure Database

Emits powerful radio frequency signals to disrupt the communication link between a drone and its operator. Forces the drone into failsafe mode (hover, land, or return-to-home).

Broadcasts fake GPS signals to confuse drone navigation systems. Can redirect drones off course, force landing, or cause them to crash by feeding incorrect position data.

Using shotguns with specialized ammunition or concentrated small arms fire to physically destroy low-flying drones. The most accessible and lowest-cost kinetic countermeasure available to ground troops.

High-energy laser system that destroys drones by burning through their structure or disabling sensors/electronics. Offers unlimited 'magazine' as long as power is available.

Specialized radar systems designed to detect small, low-flying drones. Provides early warning and tracking data for other countermeasure systems. Essential first layer in any C-UAS defense.

Array of sensitive microphones that detect and localize drones by their propeller and motor noise signatures. Passive system with zero electromagnetic emissions.

Specialized drone designed to intercept and destroy other drones through collision, nets, or onboard weapons. The aerial equivalent of a fighter jet for the drone domain.

Launches a weighted net to entangle and capture a drone in flight. Non-destructive method that allows for intelligence gathering from captured intact drones.

Exploiting drone communication protocols to take control of the drone. The most sophisticated soft-kill method — can redirect, land, or capture enemy drones without destruction. Modern cyber-takeover systems cover both commercial protocols and, with FPV-capable protocol exploitation systems, open FPV link standards (ELRS, Crossfire, TBS) and reverse-engineered unknown protocols.

Handheld or shoulder-mounted directional jammer shaped like a rifle. Soldier points it at a drone and activates to jam its control and video links. The most accessible EW countermeasure for individual soldiers.

Man-Portable Air Defense Systems — shoulder-fired guided missiles originally designed for aircraft. Can engage larger drones at altitude. Expensive per engagement but highly effective against medium/large UAVs.

Radar-guided automatic cannon systems specifically designed or adapted for counter-UAS. Uses programmable airburst ammunition for high kill probability.

Emits a burst of high-power microwave energy that fries drone electronics instantly. Unlike lasers, can affect a wider area — potentially the most effective counter-swarm weapon.

Passive system that detects drones by their radio frequency emissions. Can identify drone type, direction, and sometimes operator location.

Layered set of physical methods to counter fiber-optic guided drones, which are immune to all RF/EW (jamming, spoofing, takeover). No single system is decisive — defense relies on stacking passive detection, overhead barriers, vision-guided interceptors, and short-range kinetic engagement along likely approach corridors.

Smoke grenades, vehicle-mounted smoke generators, or large-area obscurant systems that block visual and infrared sensors on drones. Prevents visually-guided drones from acquiring or tracking targets. A simple, cheap, and immediately available passive defense.

Low-to-medium power laser system designed to blind or degrade drone cameras and sensors without physically destroying the airframe. Cheaper and more portable than high-energy laser weapons. Can temporarily or permanently disable the drone's 'eyes.'

Traditional surface-to-air missile systems (short to long-range) adapted for counter-drone roles. Originally designed for aircraft and cruise missiles, now increasingly used against large UAVs and loitering munitions. Extremely effective but cost-per-engagement is a major concern.

Generates a short-range electromagnetic pulse that disables all electronics in the affected area. Can instantly neutralize any drone regardless of type — including fiber-optic and autonomous systems. The ultimate 'hard kill' electronic weapon.

Physical barriers including camouflage nets, overhead wire obstacles, cage armor, and improvised overhead covers designed to prevent drone-dropped munitions and FPV strikes from reaching targets. The simplest and most immediately available protection.

Using decoy targets, IR flares, radar reflectors, and thermal signature reduction to confuse drone targeting systems. Prevents drones from identifying real targets by presenting false ones or reducing the signature of actual assets.
