Electromagnetic pulse weapons: It's not easy to take another step forward. Wu Qi, Gu Xiwen, Zhang Guoqiang, and Zhao Nan provide the effect picture of electromagnetic pulse weapons. Electromagnetic pulse (EMP) weapon is a new concept weapon that has gradually developed in recent years. Its killing principle is to use powerful electromagnetic pulses generated by nuclear explosions or high-energy microwave generators to destroy electronic components of enemy weapons and equipment, causing them to fail or be damaged. In future high-tech wars, this "bloodless weapon" may be one of the preferred offensive weapons to respond to information-based military forces. The birth of the concept of electromagnetic pulse weapons is quite dramatic. In 1961, the Soviet Union conducted a nuclear test near the Arctic Circle, and a severe nuclear explosion not only damaged the Soviet Air Force's ground to air radar, but also affected electronic systems thousands of kilometers away. Two years later, the United States conducted a nuclear test. After the nuclear explosion, the environment within a thousand kilometers of the explosion center was affected, and most of the lights on the streets went out. At that time, the residents of Honolulu, Hawaii were also unsure of the reason. After investigation, people finally know that the culprit of these two "mysterious events" is the instantaneous electromagnetic pulse generated by the nuclear test. Military experts have seen the military value of using the electromagnetic pulse effect to manufacture weapons, which is precisely in line with the modern concept of "non-contact, zero casualties" in warfare. Since then, various military powers around the world have successively conducted research on electromagnetic pulse weapons. After decades of development, electromagnetic pulse weapons have not yet been widely used in practical combat. As people gradually deepen their research on electromagnetic pulse weapons, their understanding of their shortcomings becomes more profound, and their applications are also subject to more constraints. For example, electromagnetic pulse weapons have a wide range of damage, making it difficult to accurately control the killing radius. A slight lack of attention can lead to the bitter fruit of "killing a thousand enemies and self damaging 800". The ability to break through development bottlenecks and overcome technological shortcomings determines the position and fate of this new concept weapon on the future battlefield. The development of electromagnetic pulse weapons in the United States was relatively early. At present, the US Navy has successfully developed an EMP warhead equipped with GPS/INS aviation guided bombs, and plans to transplant it to platforms such as satellite assisted guided ammunition, joint direct attack ammunition, agile gliding weapons, and joint standoff launch weapons. In 2016, it was equipped with the second generation EMP kit of the AGM-86C/D conventional air launched cruise missile, achieving multiple and multi target strike capabilities. The US Army began developing an EMP gun attack system using cannons as a throwing system in 2017, aiming to develop a low-power weapon that can accurately strike a small area and affect a specific part of the electromagnetic spectrum. In the "Cyberspace Exploration 2021" exercise conducted by the US Army, the focus was on testing the concept of electromagnetic integration in cyberspace and exploring the application and tactical research of integrating electronic warfare equipment such as electromagnetic pulse weapons into the entire military combat system. After decades of research, Russia has accumulated a lot of experience in electromagnetic pulse weapons. In the spring of 2020 testing, the latest electromagnetic pulse gun was able to destroy drones within the test range, exceeding researchers' expectations. The test object in Russia this time is only drones, but electromagnetic
