DAS is indeed modelled (and reasonable well), as well as the EOTS's IRST functionality.
I do have two problems with the CMANO F-35 however - the first is that its radar is seriously underpowered; the APG-81 should have about double the range as it does at the moment (a lot of AESAs in the database are rather messed up in relative performance; I've submitted recommendations).
The second is that if the database RCS values are in dBm, then they're about 10dBm (at least from the frontal aspect) too high. On the flipside, rear aspect RCS values are currently equal to frontal aspect RCS values - that shouldn't be the case. Side RCS values I have no idea about.
As mentioned, data links with the F-35 are currently fairly generic; using MADL for cooperative EW, passive IR / RF sensor fusion / triangulation, etc would be nice, but it doesn't sound like that'll be coming to the consumer version.
As for using the F-35 effectively:
1. Bring along some EW support; a pair of Growlers can seriously degrade enemy radar, allowing F-35s to get within and escape enemy missile engagement ranges without being detected.
2. When F-35's go or are about to go Winchester, you can let them stick around, but don't let them get close to the enemy.
3. If done right, flanking the enemy and harassing them can force enemies to divert forces to deal with an enemy of unknown (to them) size (just be sure to get those F-35s out of there as soon as the AMRAAMs launch; you want to be able to flank back around those enemies). This can tie up enemy assets while your main force overwhelms their other units.
4. If you're dealing with advanced threats (Su-35s, etc) then bring more than 4x AMRAAMs per target. If this means bringing 4th gens, then so be it, just be sure to make the 4th gens high-tail it after firing and let the F-35s provide target updates.
Yea, I did some tests on it, it can't detect a Nodong-2 launcher even from within the AESA range, only the launches, which tells me DAS isn't completely implemented yet, but it does detect any radar outputs from other systems, like SA-12s
