B-2 'Spirit' Stealth Bomber

With enough radar stations listening it should be possible to triangulate the location of the target... especially a system like some of the Russian ones like NEBO that uses multiple radar in different frequencies that use the advantage of the different frequencies together to spot targets they couldn't detect on their own.

Think of it like using a thermal imagers view overlayed with a day time digital video view so warm targets are highlighted... so a man wearing camouflage will stand out in the IR range so he will glow, but in normal visible light he might be heavily camouflaged yet still stand out because of his temperature compared with the background temp.

Combinations of frequencies should allow detection and tracking with accuracies that an IIR missile with a datalink could be launched to the general location and with its own seeker find and take on the target.
