Interesting...sounds like it takes alot of equipment and processign power to ‘defeat’ stealth. No way the Iranians did this by themselves.

Perhaps our pals the Russians have been gently stabbing us in the back.

Ganged radar requires data connectivity to each radar, an appropriate data interface, then something to aggregate the inputs to resolve a target. The primary expense is the radar unit. Data facilities next (underground). The aggregating location is a common resource.

The Russians are the probably source of the technology. Pure speculation, but consistent with their demonstrated track record.
