At a secret workshop in Ukraine’s north-east, where about 20 people assemble hundreds of FPV (first person view) drones, there is a new design. Under the frame of the familiar quadcopter is a cylinder, the size of a forearm. Coiled up inside is fibre optic cable, 10km (6 miles) or even 20km long, to create a wired kamikaze drone.
Capt Yuriy Fedorenko, the commander of a specialist drone unit, the Achilles regiment, says fibre optic drones were an experimental response to battlefield jamming and rapidly took off late last year. With no radio connection, they cannot be jammed, are difficult to detect and able to fly in ways conventional FPV drones cannot.
“If pilots are experienced, they can fly these drones very low and between the trees in a forest or tree line. If you are flying with a regular drone, the trees block the signal unless you have a re-transmitter close,” he observes. Where tree lined supply roads were thought safer, fibre optic drones have been able to get through.
You won’t be able to just follow the wire, it’s millimeter thin and extremely light. And drone operators need to constantly move anyway.
It’ll be hard to spot but easy to follow. But the drone and the wire don’t need to go in a straight line. Anything could be waiting on the route between the operator and the drone.
I don’t know about “easy to follow.” Have you ever followed 6 miles of transparent fishing line through an active warzone to see what was at the other end? That seems to approximate the difficulty.
It’s probably not required if not using RF.
