FPV drones owning the battlefield.... the end of an era,
FPV drones owning the battlefield was always going to be a short-term situation. The reason is straightforward: armored vehicles moving forward now carry enough electrical power and mounting space to field automated, optically guided kinetic anti-drone systems directly on the vehicle. These systems can be cued by early warning, so vehicles and their automated defenses know where incoming FPV drones are before they arrive. The drones themselves can be tracked optically and acoustically, picked up by the sound of their engines and motors, and with enough of these systems fielded, Third Corps has effectively mastered how to clear the sky of FPV drones in the area it's operating in, specifically the ground north of Lyman.
The reason so few FPV drones are being encountered in that area comes down to a deliberate, layered air defense concept. A .50 caliber machine gun has an effective range of roughly a thousand meters, which means each air defense gun protects a radius of about two thousand meters around itself. These systems can be vehicle-mounted, trailer-mounted, or pallet-mounted, simply dropped off at the front and daisy-chained together. With four, six, or twelve of them working in concert, they move forward one piece at a time, like pieces on a chessboard, always keeping overlapping fire and mutual support between systems. Combined with electronic warfare vehicles and other anti-drone systems moving forward alongside them, this is exactly what has let Third Corps advance into a large area while encountering relatively few FPV drones, whether radio-guided or fiber-optic guided.
We always knew this was coming. When large formations move forward with heavy vehicle density, combining kinetic anti-drone systems with electronic warfare sweeps the FPVs from the sky, and that's exactly what's being seen now. We saw an earlier version of this at the Battle of Kursk, where wide-spectrum jamming alone worked well for the first couple of days, until fiber-optic drones showed up and jamming alone stopped being enough. What's happening now is the second phase of that same evolution: jammers combined with kinetic air defense actually sweeping the skies clear of FPVs, rather than jamming alone trying to hold the line.
FPV drones will always have a place on the battlefield going forward, but they've always been fragile, and as long as they can be seen, they can be dealt with. What's re-emerging now, as a direct result of clearing the skies, is conventional tube artillery, finally able to do what it does best at long range again, without nearly as much fear of the FPV threat hanging over it.
