How are you getting the firing solution? Radar? Put out many megawatts
of coherent microwaves and hope that a notional "low probability of
intercept" radar is actually a "zero PoI", because Typhoon has a rather
good RHAWS of its own?

This brings up something I've been wondering. I don't know if this is
urban legend or what. Supposedly workstations dealing with classified
materials have to have the monitors shielded so signals can't be
picked up out the back? I'm wondering, when it comes to your typical
fighter if these same signals are shielded. It seems to me there
would be other sources of electrical "noise" than just an actively
transmitting radar or radio.
