The Russians claim these are a new type of Ukrainian drone-dropped anti-personnel IED, with a pressure-induced electric detonation.
As with other new Ukrainian devices, battery life eliminates the long term persistence of landmines like the Russian PFM-1. 1/
A similar device was dismantled, yielding an explosive similar to German P8301 ( “Seismoplast-1, exploded in the video).
The fuze consists of two contact plates separated by foam.
When the plates are crushed together, current from the battery initiates an electric match. 2/
Another variant with the same design principles. 3/
Fiber optic cable for control and video of FPV drones could defeat their two great enemies, EW jamming and loss of line-of-sight (LOS).
Some estimate that up to 90% of FPV missions fail, most to jamming as the drone approaches a vehicle, trench or backpack jammer. 1/
Loss of LOS occurs as the FPV inevitably must go right to ground level to complete its mission.
This is why so many FPV videos become very staticky as it closes the target.
Fiber optic cable is immune to radio jamming, and doesn’t care about LOS. 2/
The FPV carries a spool from which the fiber flows out freely, so it cannot be tethered by a tangle.
The drone can fly in circles, through groves of trees, and even backwards.
The cable is apparently surprisingly hard to break. 3/
