In the latest German Bookazine "Fliegerrevue X"is an article about the Trommsdorff D-6000 ramjet cruise missile.

Hydrogen fuel for a tactical air-launched, expendable?
Supposedly they've taken to Methane of late, but your point largely stands.

Earlier in the thread, we had the GT2 90mm mounted on I think a 17 pdr carriage. It was apparently used for testing or development work, although I've seen it described as a "demonstrator" too.
See some additional pics below.
I wonder if this was an offshoot of that, after testing results, with a much lighter carriage suitable for airborne use?

Idle speculation on my part...

I also wonder if that carriage on the lighter parabat version is purpose built, or repurposed from a lighter weapon...anybody know?

I wonder if Reaction Engines might be in on the Lockheed bid. They have a US operation which is tied pretty tightly to LM, and they seem to have been pretty active of late. On the other hand, still seems like a lot of engine to put on an expendable weapon.

Very good reference providing relative merits of different configurations:
https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19930008694.pdf

starting p.104 there's a discussion of tiltrotors.

I discovered this report from long time ago.

Root t/c went up: 10-11%! So yes, 'Thin Wing' seems a misnomer.

Despite this, outer panel was 5%, so average was 7%; in effect thinner, but with the benefits of a lighter structure due to deeper root.

Original intent was 7% for the whole wing, but the chosen option was seen as better overall due to lower weight.

There was a 5% wing discussed for the ultimate P.376 that is in all the books, but this was rejected in favour of the projected fat/thin wing, and Mach 1.8ish was supposed to result.

Despite all the articles on F.155, it seems F.153 was of more interest in some ways (and one prototype was being built).

...always wondered why the so-called thin wing Javelin projects did not have thin wings at all.
