Yes, I fully agree with you.

It's not perfect, but it certainly greatly increases the probability of getting some range/geolocation data. The EOTS could also be slewed for an extra point of reference (as well as radar/ESM.)


I certainly agree with what you said above!

Useful? Certainly. But it’s not symmetric and the proximity of the sensors to each other makes the solution somewhat less accurate than a fused solution provided by sensors more widely spaced. If ownship data is all you have, that’s better than what anyone else is flying with. The other glory is that the jet tells the pilot which sensors are contributing and provides a confidence level in what it is providing.

“In the video you have a triangulation made by a 2 F-35s, that's correct. But then again, it should be possible to perform triangulation without a second F-35 (although and granted with a 2nd or better a 3rd and 4th F-35 would be better/preferable), this by resorting to another source. Again, using a second DAS sensor or better yet, the EOTS would provide a good source of ID and triangulation.“

Yep. That’s called fusion.

Spaz has a slide somewhere that provides a conceptual depiction of how the fusion engine works. Many think it is simply the aggregation — on one display — of what the jet knows about the world around it. That’s not the magic; the magic is how it tasks the sources it has available to keep track of, or learn more about what it sees and what it thinks it knows — and the pilot doesn’t need to tell it to do so.

What's the word on the DIRCM for the F-35??? Are they still developing the Northrop Grumman "The Threat Nullification Defensive Resource — ThNDR" for the aircraft and when is it suppose to be available??? (block 5/6?)

There's been no word on ThNDR for a few years and there's zero indication that it's being procured for Block 4. Stakeholders probably want to first see what happens with things like the USAF's SHiELD program - no point spending a bunch of money on DIRCM if the F-35 could instead get a laser that acts as both DIRCM and destructive HEL.

It's unlikely you could mount such lasers into all F-35s (like you presumably could with ThNDR), but if HELs work well enough against missiles then it might be more advantageous to just have a portion of the fleet flying with something like an LO-podded or weapon-bay-mounted laser.

Are those fingerprints or is it the way that the screen looks when turned off?
