Fancy. Looks like they are making the F-15 do what the F-14 did. Only better and more modern and networked.
My initial reading keyed on the words "radar-denied environment" which is significantly different. The F-14 had to illuminate its targets with its onboard AWG-9 radar, which would broadcast its presence, even though the Phoenix missiles had their own terminal guidance.
If I read correctly, this would allow the F-15s to see what is out there without revealing themselves by turning on their radar.
That would be pretty slick...
