Raytheon AGM-181 Long Range Stand Off Weapon (LRSO)

Wow! The most detailed photos to date .... the body cross section does not look very trapezium-like ....
 
Probably a NACA duct masked by the folded wings, if I had to guess

Edit: welp, great minds think alike lol
If I had to guess (and I do) probably hidden under the folded wings like JASSM.
That is the only explanation for the inlet ....

The next interesting thing to find out is the design of the jet exhaust .....
 
Looks like this is for easy and clear separation of the exhaust covers. Apparently, the exhaust is rectangular perhaps with seration but we can't see that here.
Your comments reminded me of the JASSM, which needed 2 small panels near the exhaust jet pipe to aid in the store separation phase .... these 2 panels helped the JASSM to have a pitch down tendency to clear the carriage aircraft, and are jettisoned once the separation phase is completed .....

Ah, that explains the airfoil looking tab projecting downward…probably creates lift to angle the nose downward.
 
In that case it would appear to be a moderate sweep of about 25 degrees (The same wing-sweep as the AGM-86 ALCM).
I thought it looks closer to 40deg ....

Any guess what is the black diamond thingy nearer the nose? DSMAC camera?

I do not see radar altimeter antennas at the belly ... either there is none, or will only be exposed after the wings are deployed .....

IIRC the AGM-86A (The initial short-nosed version) had a 35-degree wing-sweep but the was reduced to 25-degrees in the AGM-86B.
 
Thank you for those new pictures. Looks an awful lot like the MBDA FCASW?

It does have some aspects of one of the FCASW concepts (the long range, subsonic one). But the most recent mockups of the, now named, Stratus LO, abandoned that design that they'd been using for years and went back to an almost Storm Shadow shape. Which was really odd. No-one seems to have actually asked MBDA why they changed it...to an untrained eye the original seemed to be a far more sophisticated LO design...
 

Meink: Long-Range Nuclear Cruise Missile ‘Going Well’ but Entering Critical Phase​

https://www.airandspaceforces.com/long-range-nuclear-cruise-missile-development-meink/
Air Force Secretary Troy Meink told lawmakers May 20 that the program to build a new long-range nuclear cruise missile is performing “very well” in both cost and schedule—but will require support as it enters a critical phase.
