Countering Small FPV
Kamikaze Drones
A Comparative Analysis of Military and Commercial Solutions
The Evolving Battlefield
The conflict in Ukraine has demonstrated the transformative impact of First-Person View (FPV) kamikaze drones on modern warfare, with drones responsible for 60-70% of equipment damage and both sides producing millions of units annually.
Executive Summary
The proliferation of FPV kamikaze drones has created an unprecedented challenge for modern militaries, characterized by extreme cost asymmetry and rapid technological evolution.
Key Findings
- • Directed energy weapons offer $1-5 per shot costs
- • Fiber-optic drones are immune to EW jamming
- • AI-guided systems reduce operator dependence
- • Layered defense is essential for effectiveness
Threat Overview
The conflict in Ukraine has served as a stark demonstration of the transformative impact of First-Person View (FPV) kamikaze drones on modern warfare. These relatively inexpensive and accessible unmanned aerial systems have become a ubiquitous and potent threat, fundamentally altering battlefield dynamics [44, 264].
The Cost Asymmetry Challenge
Defense Secretary Pete Hegseth noted the unsustainable pattern of using "exquisite multi-million-dollar weapons" to shoot down increasingly sophisticated drones that may cost only a few hundred dollars [9]. This economic imbalance puts a disproportionate burden on the defender.
Fiber-Optic Guidance
Fiber-optic guided FPVs are largely immune to conventional electronic warfare jamming, as control signals are transmitted through a physical cable [3, 22].
- • Operational radius: 5-20 km (up to 41 km reported)
- • Immune to RF jamming
- • Higher cost than RF drones
AI Integration
AI-enabled drones can operate with higher autonomy, potentially identifying and homing in on targets without continuous operator input [33, 65].
- • "Fire-and-forget" capability
- • Reduced vulnerability to jamming
- • 3D-printed components acceleration

- • Specialized interceptors like Khizhak Shooter
Challenge: NATO Innovation Challenge focused on countering fiber-optic drones through hackathon [153]

- • Advanced sensor fusion with AI processing
- • Adversarial attacks on computer vision
- • Physical destruction remains viable
