Need suggestion on implementing the HUMRAAM

[PlasmaKrab]

I've already started dealing with MANPADS as far as figures are concerned, but medium-range radar-guided SAMs are much more hazy in my mind (and my sources) for now.
From what I can tell, your accuracy value should be in the right range. You could probably go for 150/160 (after all the old S-300 gets 160 already), but given that the first ground-launched missiles (Norwegian NASAMS and early CLAWS) were certainly early AIM-120A/B variants, the choice is up to you regarding which you want to model.

Actually the official Norwegian OOB includes a NASAM (OOB 29, weapon 138), which could probably do with some upgrading, based on the AMRAAM data I could find.
Warhead of the early versions is quoted at 23kg, i.e. nearly twice that of a 9M33Mx aka SA-8B, which already gets a WHS of 10 and HEK of 18 in the Russian OOB.

Other than that, do you have any hard data on the actual range of the ground-launched missile? GlobalSec gives 20mi as range, which sounds ridiculously low for AtA (DesignationSystems.net gives 30-45mi for early versions and 65mi for second generation), so could that be the ground-to-air range?
And what about the minimum range? There's no first-stage booster AFAIK, but that also means low maneuverability at short ranges, and the launcher shouldn't be easily pivoted around (at least the Hummer-based version). Also the airframe itself isn't exactly meant for low-altitude engagements. In your opinion, how does all this works out?

Just my 2c, I've some interest in this one, but not much to offer alas...
