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.

Passive electro-optical / infrared sensors paired with computer-vision classifiers that detect, track and classify drones from imagery without emitting any signal. Increasingly the backbone of modern C-UAS sensor fusion.

Dismounted, soldier-carried jammer covering common drone control and GNSS bands. Provides a personal protective bubble against COTS quads, FPVs and commercial drones in dismounted patrols, raids and convoy halts.

Friendly interceptor UAV that hunts and entangles hostile drones using a deployable net. Provides an attritable, scalable kinetic option against fiber-optic and small autonomous threats that defeat traditional EW.

Multi-node passive sensor network that locates the drone AND its operator by triangulating their RF emissions (TDoA / AoA). Critical for finding pilots of fiber-optic-blind systems and for targeting EW or kinetic effects on the launch site.

Defensive position/navigation/timing protection for friendly platforms — controlled-reception-pattern (CRPA) antennas, multi-constellation GNSS receivers, and inertial backups that resist GPS jamming and spoofing of one's own assets. Indirectly counters adversary GNSS-attack drones and makes friendly drones resilient.

Rifle-mounted computerized optic that detects, tracks, and locks onto small UAVs, then only releases the trigger when the bullet will actually hit. Turns any infantryman with a standard service rifle into a viable last-line C-UAS shooter against quadcopters and FPVs at 50–250 m.

Wire mesh or fishing-net curtains strung over roads, trenches, ammunition dumps, command posts, and CASEVAC routes. Forms physical 'drone tunnels' kilometers long. The cheapest and most reliable area-denial measure against FPV strikes — defeats both RF-link and fiber-optic FPVs because the kill mechanism is purely mechanical.

Vehicle- or pedestal-mounted autocannon firing programmable airburst ammunition (Oerlikon AHEAD, Bushmaster 30×113, XM1211). Each round dispenses ~150 tungsten subprojectiles at a programmed range, forming a lethal cloud — no direct hit required. Solves the 'magazine depth' problem of missile-based C-UAS at one-tenth to one-hundredth the cost per engagement.

Long-range acoustic device aimed at small commercial drones to induce resonance in MEMS gyroscopes and IMUs, destabilizing flight. Honest assessment: largely a research curiosity and anti-personnel hailer — effective only against unprotected hobbyist quads at short range. Included for completeness; not a primary military C-UAS solution.

Detection system that exploits ambient RF signals (FM broadcast, DVB-T, cellular, Starlink) reflecting off airborne targets. Emits nothing itself — invisible to adversary SIGINT and immune to anti-radiation drones. Among the few sensors that reliably detect RF-silent fiber-optic and fully autonomous drones.

Software backbone that fuses radar, EO/IR, RF, and acoustic sensors into a single common operating picture, then auto-cues the cheapest effective effector against each track. Solves the swarm problem: every individual sensor and effector above fails when 20+ tracks appear simultaneously. This is the actual difference between systems that survive Shahed waves and systems that don't.
