Electronic countermeasures suite controller

A device used in electronic warfare (EW) that emphasizes the older term of electronic countermeasures, but, in the modern classification, usually combines features of electronic support, electronic attack, and electronic protection. Practical implementations usually contain at least one basic electronic warfare function, such as a radar warning receiver or electronic warfare expendables dispenser.

Examples include the AN/ALE-47, of which the core feature is a countermeasures dispenser, and the AN/APR-39, based around a radar warning receiver.

As a controller, the device has multiple ways to interconnect with the devices it controls. Most commonly, in Western EW systems, this is the MIL-STD-1553B bus, but there is an increasing tendency to use commercial-off-the-shelf interconnection technology such as Ethernet-family devices, possibly ruggedized for the military environment.
