When Price launches a nuclear bomb and explodes in the atmosphere, it will produce EMP, that is, electromagnetic pulse electromagnetic pulse is a physical phenomenon, which has the following two meanings: (1) explosion (especially nuclear explosion), lightning, sunspot, electromagnetic radiation produced by conduit effect or electric spark, or alternating electromagnetic field which changes dramatically with photoelectrons due to Compton scattering or photon scattering, and acts on electronic materials, blasting equipment or surrounding media. Gamma rays generated by a nuclear explosion will radiate from the explosion point to the surroundings at the speed of light, collide with oxygen and nitrogen atoms in the air, and produce negatively charged electrons and extremely strong electromagnetic fields (commonly known as electromagnetic pulses). This electromagnetic field may couple electrical equipment or electronic equipment and generate destructive current and surge. See EMP for the damage effect on electrical appliances. Electromagnetic pulse can hardly be detected outside the impact range, unless the equipment is a nuclear weapon or a weapon specially used to generate electromagnetic shock waves; (2) A broad-band, high-intensity and short-lived electromagnetic energy burst. The frequency width of the electromagnetic pulse generated by a nuclear explosion or asteroid impact is 3 Hz to 30 kHz.

At that time, in Washington, the US military could no longer hold on. Without EMP to destroy the Russian helicopter, the American army lost. Uncle is not necessarily a camp, but both sides have common interests and use each other. Unfortunately for that satellite, the shock wave from the explosion destroyed it.
