In the United States, the drone-killer of the Russian S-400 was tested.

The US military tested the unique unmanned aerial vehicle RQ-180, which, due to its low radar signature, long flight duration and flight altitude up to 18 kilometers, was called the killer of the Russian S-400 Triumph air defense system in the United States.

“According to the Aviationist, although the US Air Force did not officially acknowledge the existence of this aircraft, being“ embarrassed ”to confirm the existence of a new line of UAVs that could help break through Russian defenses, attack and return to base, this is no longer the case. To accomplish this task, the RQ-180 was designed to resemble the B-2 Spirit stealth bomber with an aerodynamic wing shape and a coating that absorbs radar waves ... The RQ-180 has a wing-shaped aerodynamic system with carefully designed contours and an invisible antenna system. To date, seven prototypes of the RQ-180 have been built, which are used in reconnaissance and remote sensing operations in the depths of enemy air defense. A special feature of this line of drones is that the RQ-180 can continuously operate in the air for 24 hours at an altitude of 18 km - an altitude that can exceed the interception threshold of many of the world's most advanced air defense systems. The fundamental design feature of the RQ-180 was improved radar evasion over the Lockheed Martin F-117, F-22 and F-35 aircraft. ", - about it сообщает DatViet edition.

Despite the fact that the exact characteristics and capabilities of these unmanned aerial vehicles remain unknown, experts draw attention to the fact that drones are equipped with special means that allow them to identify weaknesses in enemy air defense systems, while remaining invisible to them, however, the likelihood that The RQ-180 will be able to get close to the C-400 air defense system is very small, although it is not completely excluded.

"Until recently, it was believed that the Favorit air defense system was also invincible, but after several anti-aircraft missile systems were destroyed in a week, there were very big doubts about the reliability of the S-300.", - the analyst stressed.
