Not to sound like an F-22 cheerleader but I thought this was interesting. . .

Go back and take a look at '50s vintage fighters. Managing an intercept
on a
high-subsonic bomber using strictl GCI-only at night was a bitch and it
failed. Often. That's why the F-86D et al had on-board RADAR.

Fine,if you can get F-86D close enough to stealth bomber even its vintage
radar
could detect stealth aircraft.

Going to use the air data probe for FOX-4? Get a life. Stealth works
superbly against X-band RADARs. In case you didn't understand, even with
MagicTech multistatic RADARs, the interceptor is going to be effectively
blind, none of his guided weapons will work and he's reduced to being a
Hawker Hunter blindly poking around the night sky aided by hints from the
GCI site.
