No matter how many drone jammers a crew puts on their vehicle, it is no guarantee that any of them will succeed in stopping a drone attack. This is graphically illustrated here by this burned out Russian UAZ-452 series van. The crew had placed no less than four multi-channel drone jammers on each corner of the van's roof. That they were multi-channel can be told by each set having more than one antenna though the driver's side set has lost all of its antenna from the drone strike. We can see that the sets were at least 4-channel jammers, meaning, each antenna jammed a specific frequency (channel) that drones are known to operate on. The crew added a wire mesh cage which covered the front, a small portion of the sides of the van, and the portion of the roof over the front seats. Not that any of it prevented the Ukrainian drone (or drones) from successfully hitting the van.
In part, this strike could be due to the Ukrainian FPV drone being capable of operating on multiple frequencies. If the drone detects its control signal is being degraded by an active jammer, it automatically switches to a different frequency. This is one reason both Russian and Ukrainian deployment of drone jammers on vehicles almost always incorporates more than one jammer in the hopes that a wider frequency range can be jammed. Another possibility is that the drone's video feed was jammed but the operator had already put the drone into its terminal flight path and simply kept the controls locked so that the drone still flew into the van.
Speaking of the UAZ-452, it is a 4-wheel drive, off-road van which has been in production since 1965. Originally made for the Soviet military, the UAZ-452 can also be found in large numbers in civilian versions. The UAZ-452 is nicknamed the “Bukhanka” which means “Loaf” due to its shape that looks like a loaf of bread. Because the Russian logistical complex is unable to adequately provide units with military transport or even armored personnel carriers to replace losses, Russian troops have been using the UAZ-452 and its variants more and more as front-line transport and in some cases, as assault vehicles with disastrous consequences.
It is probable the burned out remains is a UAZ-39625, one of the more recent versions of the original UAZ-452. It can seat 8 and the van is powered by a 2.7-liter petrol engine that develops 112 horsepower. This is paired to a manual transmission with a 5-speed gearbox and a 2-speed transfer case. On roads, the UAZ-39625 can reach a maximum of 79 miles per hour and 55 miles per hour, the van consumes 3.6 gallons of fuel every 62 miles. Total fuel capacity is 20 gallons.
