The Eurofighters IRST is much better than the Raptors,

AFAIK the F-22 doesn't have one *at all*. IF the Eurpfighter's has
to be cued by the radar then it's pretty much dead meat against the
F-22.

No, PIRATE's autonomous.


Unless the IRST out ranges AMRAAM it's pretty much in the same
boat.

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.



Untrue- the classified workstations that I deal with use the same
monitors as any other terminals- they do have to be separated (by
either 30 inches or 3 feet, IIRC, which obviously I don't) from
any unclassified system, however.

Some facilities are shielded against signals leaking out- TEMPEST
is the overall designation for the standards which are used to
determine adequate signal attenuation, IIRC. Not sure how many
facilities are using TEMPEST nowadays.
