Fibre-optic drones: The phantom that flies
Practice PYQs on this topic
500+ questions on Science & Tech with explanations
📌 Summary:
-
Fibre-optic guided drones are proving to be a disruptive force in the Russia-Ukraine conflict and parts of the West Asia war
-
How they work: Drone is guided by a thin fibre-optic cable that unspools behind it during flight; communication happens via light signals through the cable — immune to all electronic/RF jamming; real-time video feed transmitted to operator; cable breaks automatically at target
-
Key characteristics: Low-cost, hard to track, harder to stop, capable of swarming; not constrained by electronic jamming or GPS denial; persistent low-altitude strike capability
-
Battlefield impact: In Ukraine and southern Lebanon, fibre-optic drones have "redefined the front line" — enabling strikes in heavily contested zones where RF-guided drones are easily jammed; battlefield control increasingly determined by ability to deploy and adapt such systems rather than scale of conventional weapons
-
Why they defeat countermeasures: Conventional C-UAV (counter-UAV) systems rely on jamming drone communication signals (RF/GPS) — fibre-optic drones use light signals through a physical cable, making signal jamming ineffective; only physical interception or kinetic kill works
-
Implications for India: Pakistan and China may induct fibre-optic drone capabilities; India needs to develop effective C-UAV systems that go beyond electronic jamming; border terrain in J&K and LAC makes this threat particularly relevant
-
Strategic significance: Marks an inflection point in modern warfare — cheap, expendable, scalable systems disrupting expensive conventional weapon platforms
