"Judgment Day" drills: China tested military communication technologies to prepare for a potential nuclear strike.

According to data from the publication South China Morning Post, researchers explored a scenario in which a nuclear explosion occurs at a high altitude, several tens of kilometers above the ground. This type of attack, known as an electromagnetic pulse (EMP) from a high-altitude nuclear explosion, has the potential to destroy electronic equipment.

The standard military equipment requirements in China and the USA state that any equipment certified as EMP-resistant must operate after exposure to an electric field intensity of 50 kilovolts per meter. However, as reporters clarified, for their experiment, Chinese scientists raised this threshold to 80 kilovolts per meter.

According to the test results, the equipment was able to function after a brief delay, and the data transmission network remained intact.
