Someone on reddit claiming to be on a Burke DDG stated that the standard operating procedure is to always run with full SLQ-32 EW capability turned on outside of port. Is this really true? It sounds stupid to have such a sensitive system always online for every potential adversary to study, and wouldn't it be dangerous to jam radars around a ship in peace time?
Turned on with full capabilities does not necessarily mean it is emitting: it could be in auto mode, and starts jamming when it detects a threat. That's feasible if the false alarm rate is low.
