Electronic warfare gained its development in the Great Patriotic War. In the postwar period, it was allocated to a separate EW service. In modern conditions, due to the broad saturation of troops with electronic equipment, the EW has received a new impetus for its development.
Today, electronic warfare, as one of the most important types of combat support, is of strategic importance. It performs the tasks of conducting electronic intelligence, defeat the enemy's electronic systems and protect its radio electronic forces and assets.
