The reason why Russia's `invisible assassins` struggled against Ukraine's cheap UAVs 0
(Dan Tri) – While Ukraine increases the production of cheap UAVs, causing damage to Russia, Moscow’s electronic warfare assets have not been able to effectively intercept Kiev’s simple weapons in recent times.

When Republicans in the US Congress began blocking the aid bill for Ukraine starting in October 2023, Kiev lost one of its main sources of artillery shells.
Ukrainians have sought to adapt to the situation, promoting the production of first-person unmanned aerial vehicles (UAV PFV).
With an attack range of more than 3km, these small UAVs can rush into Russian vehicles, and even chase and attack Moscow’s soldiers.
Currently, FPV UAVs are said to be the weapon that causes the most damage to Ukraine’s opponents.
It is not without reason that Russia installed a series of radio interference devices on vehicles.
However, Russia’s problem is that these electronic warfare systems have not worked effectively in recent times.
Russia is constantly improving electronic warfare equipment.
When FPV UAVs replaced artillery as the most serious threat to Russia’s ground forces late last year, the Russian military responded by attaching to its armored vehicles any number of disruptive devices.
First, Russia mounted on armored vehicles the RP-377 handheld jamming device, which was developed by the Kremlin to protect Moscow troops in Syria from explosive bombs using radio waves.
Ukrainian UAV expert Serhii Beskrestnov analyzed an RP-377 system that Kiev confiscated from Russia and concluded that this weapon has high-quality interception capabilities.
However, the disadvantage of this system is that the protection range is very short.
This is clearly a weakness in Russia’s jamming capabilities that Ukrainian soldiers operating UAVs exploited late last year and early this year.
Russia has recognized the problem on the RP-377, and launched a 2nd generation jammer version called Volnorez, with a protection range of about 800m.
However, the disadvantage of Volnorez is that the jamming ability of this system is far inferior to that of the RP-377, Forbes quoted several Russian military bloggers as saying when dissecting the new system.
Volnorez’s biggest weakness is that it radiates too much heat.
So now the Russians are replacing the Volnorez with Saniya jammers that have a range of nearly a mile.
However, one thing that cannot be denied is that Russia is a powerhouse in electronic warfare and Moscow has skills and experience in developing jamming systems.
