Electronic Support (ES) within Electronic Warfare refers to which activity?

Gathering information about enemy electromagnetic activity to support EW operations

Electronic Support is the information-gathering part of the electromagnetic picture. It uses sensors and signals intelligence to detect, identify, and locate enemy emissions—radar, communications, or other RF signals—and to characterize the spectrum environment. This data on frequency, timing, power, and location feeds EW decisions, helping to shape when and how to apply electronic attacks or protections. It’s not about supplying power, encrypting transmissions, or conducting rescue missions, but about understanding what the enemy is emitting and where those emissions come from to support the overall EW plan.
