Drone Attack on Russian Facility
A series of 10 drones successfully penetrated Russia’s air defense network, flying 625 km into Russian territory to target a secret facility. The drones used a simple trick with their propellers to evade detection, creating a distinctive pulse in the radar return that made them nearly invisible to state-of-the-art radar systems.
Evasion Tactics and Countermeasures
The drones employed various tactics to evade detection and destruction, including cutting their engines to avoid missile strikes and deliberately sacrificing one of their own to save the others. However, the Russians utilized sophisticated electronic warfare assets, including a Borosogl 2 system and a Mosva 1 electronic intelligence system, to disrupt the drones’ navigation and locate them.
- The Borosogl 2 system emitted 100 watts of interference, overpowering the faint GPS signals and causing the lead drone’s GPS receiver to lose signal.
- The Mosva 1 electronic intelligence system used direction-finding math to accurately locate the drones, waiting for them to make a mistake and reveal their position.
Electronic Warfare and Jamming
A powerful electromagnetic jamming system was used to disrupt the drones’ navigation, causing their screens to go dark from 8 km away. The Russians also employed an acoustic reconnaissance system, called 1B75 Penicellin, which detected a drone by listening to the sound of its engine and calculating its location by analyzing the slight differences in arrival time of the sound at each microphone.
Missile Attacks and Evasive Maneuvers
The drones faced multiple missile attacks, but they were able to evade destruction through a combination of evasive maneuvers and software glitches. The lead drone was destroyed by a missile’s warhead, but its destruction saved the other drones, which then executed random throttle changes to destroy the missile system’s firing solution and evade the second missile.
GPS Spoofing and Final Attack
The facility’s defenders prepared a special defense against the drones, using a Pole 21 GPS spoofing system to broadcast fake GPS signals and confuse the drones’ navigation systems. However, the drones were able to navigate through the chaos and finally target the Poliana D4M1 assembly building, striking at a precise angle and velocity to penetrate the steel roof and rupture chemical storage tanks.

Grammar Focus: The Use of the Passive Voice in Technical Descriptions
The passive voice is often used in technical descriptions to focus on the action rather than the doer of the action. This is particularly common in scientific and technical writing, where the emphasis is on what is done rather than who does it. For example, in the text, 'a series of 10 drones was used to target a secret facility' or 'the drones were equipped with a simple trick to evade detection'. The passive voice is formed using the verb 'to be' in the correct tense and the past participle of the main verb.
