Thanks, I always liked that Boeing Phantom Works design, it's nice to finally see the planform, as opposed to the usual isometric image they have shown repeatedly.

Funny, it's a classic swept wing come back. Almost a F-100 Super Sabre wing in plan view.
Ok , just a concept anyway I suppose...

I'm sure that's exactly what that is and not just generic artwork to fill a page. :-\ I'm sure swept wings will do wonders for landing speed and short field performance, especially given that there are no thrust reversers shown.

To me looks like the original ATF from Lockheed, but with intakes on dorsal. Not impressed, I don't like it (the Boeing 6th Gen). Just my $.02 cents.

Still think Lockheed Skunkworks has the best concept art so far. Just says "Penetrating Counter Air" to me.

The NGC 6th Generation Fighter (6GAFS) has several (eight?) sensors mounted directly on the canopy transparency.  Does anybody know their purpose and the reason for their unusual placement?

Sorry, I don't have moar: the top photo is a model on the desk of NGC's Chris Hernandez (published by the Los Angeles Times, if I remember correctly).  The bottom illustration came from NGC and was posted on this thread by Flateric about two years ago.

As you can imagine, I could use moar as well ...

Circle5, my guess is the elements in the canopy is a system for controlling the transmittance of electromagnetic energy. NGC conducted experiments with energizable liquid crystal panel structures in the late 1990's for a canopy that prevented electromagnetic energy transmittance through the canopy using multi-pane canopies with a liquid crystal structure in the middle. When the system is on the canopy becomes opaque, varying from partially transparent to fully opaque depending on its setting. Not sure if this is the same thing, just a guess.

Interesting facet of the NGC concept: the structure would allow informational displays to be projected in the canopy (e.g. target cueing information, artificial horizon, etc.). Again, just a thought. I don't know if this is the case for this design.

I was thinking that's a UCAV variant of an aircraft that is optionally manned and that is a a view of the "cockpit" on the unmanned version.

That patent information from the 1990s corroborates what Dynoman was explaining – thank you Flateric.

What is described here is basically an embedded liquid crystal film, that turns the canopy opaque or transparent when energized, like on the Maybach automobile glass roof.

The HUD and external video projection possibilities are interesting, although today's F-35 helmet visor is capable of doing most of that (except for the EMT and laser shielding of the cockpit and pilot).  If this NGC fighter does feature a canopy-opacifying system, I have my doubts that it would take the form of a bunch of 4-5 inch diameter discs stuck directly on the transparent canopy.

So for now, I’m going with Sundog’s suggestion of a temporary sensor suite placed inside the canopy for unmanned mission configurations (replacing the eyes of a pilot and probably more).

Northrop-Grumman engineers working on this program might laugh their heads off if they ever read our interpretation of these dots – assuming we’re way off-base, of course.  Which we're not.

Me too. They do seem optimally placed to replicate a pilot's PoV. Of course, it could also be combined with controlled transmittance to provide a pilot with a synthetic view when the cockpit is 'dark'.
