Turning off your anti-aircraft radar when it detects an aircraft doesn’t sound particularly effective.
It is when a first generation homing anti-radar missile is following the radar emission back to the source.
“Turning off your anti-aircraft radar when it detects an aircraft doesn’t sound particularly effective.”
It’s great from the point of view of a strike force, which may require only a couple minutes (or a mere 30 seconds) to get in, put ordnance on target, and get clear.
If the radar-attack birds of the strike force can intimidate the fire control radar into shutting down just long enough to get the rest of the strike force through, they’ve done their job - more cheaply and with less risk than if they’d fired an ARM.
