Net Gun / Net Launcher
Physical BarrierOpen-Source Verified
Launches a weighted net to entangle and capture a drone in flight. Non-destructive method that allows for intelligence gathering from captured intact drones.
How It Works
A compressed air or pyrotechnic launcher fires a weighted net that expands in flight. When it contacts a drone, the net wraps around propellers and airframe, entangling them and causing the drone to fall.

Advantages
- + Non-destructive — captures drone intact
- + Intelligence value from captured drones
- + Low cost per engagement
- + No electronic signature
- + Simple to operate
- + Safe in urban/populated areas
Disadvantages
- − Very short range
- − Single shot — must reload
- − Ineffective against fast or high-altitude drones
- − Cannot engage large military drones
- − Limited to small/medium drones
Tactical Deployment Tips
- ▸ Position at likely low-altitude approach routes
- ▸ Best for defending specific entry points
- ▸ Use drone-deployed nets for greater range
- ▸ Combine with detection systems for early warning
Limitations & Vulnerabilities
- ⚠ Only effective against small, slow drones at very close range
- ⚠ Cannot engage fixed-wing or high-speed targets
- ⚠ Not a viable primary defense system
