Many Ukrainian groups have been raising funds to build large numbers of such drones, like internet provocateurs NAFO, who are collecting funds for 240 attack drones for $700 each, and activist Serhii Sternenko, who is funding 500 drones at $350 apiece. Russian forces have also been using such drones, but complain about the difficulties with bureaucracy and lack of official support.
While there are certainly hundreds or even thousands of FPV attack drones in play, 50,000 would mean attacks on an unprecedented scale. As Russian Engineer notes, the need for one operator per drone, and the fact that there are only so many control channels available, means that there would only be a few drones per kilometer of front at a time – but waves of them could keep coming until they destroyed every target.
“Our EW [Electronic Warfare] installations have many drawbacks - there are not many of them, they are large, and are in themselves interesting targets. You need a lot of small EW installations so that they are everywhere,” writes Russian Engineer, noting that this would take time and money, which the Russians do not have. He also mentions the shortage of portable anti-drone guns which also jam the drones’ control signals.
Something more basic might be necessary.
“According to the feedback from the fighters, a shotgun helps specifically against such FPV, specifically the Saiga-12,” writes Russian Engineer. “They fly at low altitudes, and a good shooter may well shoot down this drone.”
