Do you know what "semiactive" is/means?

I guess so.

Doesn't sound like it.

Command guidance? I'll bet a HARM would just LOVE that.

Sure,but you will need a HARM with at least 150+ miles range to start with.

Why? You damn sure aren't going to be able to hide a 150+ mile SAM.
We'd be taking those babies out with JASSM and Tomahawks before *any*
aircraft got near. That's if someone were to actually deploy such a
system of course. And if it actually worked. Besides, to use your
150 mile SAM you'd have to bring your command link online and that's
when the HARM would pop him. It could be 10 miles away, it doesn't
matter.





An active radar seeker on a AAM likely wouldn't work very well against
stealh. You'd be better off with an IIR seeker.

If you can come close enough to stealth (or stealth comes close enough to you
)everything works.

You're talking *maybe* a couple miles. An IIR would see it further
than that. No way, NO way will an active radar seeker in an AAM pick
up a stealth aircraft from fifteen or twenty miles. They don't even
do that for NON-stealth aircraft.




If you want to increase your chances you might even upgrade SAMs with multi
spectral seekers.

Multi-spectral? Do you just stick these terms in wherever you think
it might sound right? You essentially have various form of radar and
light. ALL forms of active radar in a missile are high frequency or
REALLY high frequency. Non of which are useful against a stealth
aircraft. There is laser beam-riding, but not on a 150 mile range
missile. Optical guidance for SAMS means optics on the ground and the
missile is command guided. They don't have cameras in the nose of
SAMs like a Maverick. Because of LOS limitatons (among MANY other
things) you aren't going to be able to use optical guidance for a 150
mile SAM. Using a laser designator won't work for many of the same
reasons. Nope, IIR is your best bet. Use your Magical Multistatic
Vaporware Radar (MMVR) to cue the missile and the IIR seeker for
terminal guidance.





A high frequency radar against a stealth aircraft?

But of course,during terminal phase everything works.We are talking about very
close ranges.

What, a mile?
