Hadn't seen this depiction of 3DELRR before. From GAO's April 2018 "Weapons Systems Annual Assessment."

The NACA report is possibly "Full-scale wind tunnel tests of the Vought-Sikorsky V-173, April 28 1942"

Its not available on NTRS though
Alternate roles for AHRLIC include surveillance, pipeline patrol and spotting for water-bombers. Several USAF-surplus Bronco 1s spot forest fires and lead larger tankers to drop sites.
Here is the often read discussion of FCS gun alternatives back in 1997 which could prompt discussion today. Binary liquid propellants that have been patented after 97 render LP much safer and deserve a look.
Early Aircraft Projects / Japanese jet flying wing study

Sounds pretty notional but maybe something more has survived?

"Captured documents indicate that, as far back as 1941, the Japanese were considering jet-propulsion as a means of powered flight, and that by early 1942 they had developed the theory of a turbo-jet power unit, had the basic design of such a unit already completed and had evolved the design of an aircraft— of the flying-wing type - powered by two turbo-jet units"

"In the fields of turbo-jet propulsion research, a captured document reports on the results of experiments during the period April 41 - March 42 as carried out at the Naval Air Technical Depot, presumably at Yokosuka. That document, stated to be the sixth report on the sub­ject, includes & theoretical treatment of pressure and temperature distribution in & turbo-jet unit together with an analysis of the thermodynamics of such a unit. The report concludes with a schematic diagram of a turbo-jet unit, together with a tailless aircraft powered by two such units."

During late 1944 and early 1945 Japanese representatives in Germany exhibited a keen interest in this aircraft , an improved version of the Fw-190. In November 1944, the Japanese in Berlin were preparing to forward material on the TA-152 to Tokyo. By January 45, the Japanese Army representatives in Berlin had acquired an outline of the construction, general plans, a list of materials used in construction, and a list of equipment to be used with the Ta-152.

The contract for purchase of manufacturing rights for this aircraft was not signed until 26 March 45, although release was granted in January. A captured German Air Ministry letter, dated 5 January 45, authorizes the fulfillment of a Japanese request for rights to copy the Ta-152 C and H. The necessary drawings were to be prepared without delay -- at least general drawings if time did not permit the preparation of full blueprints. Those drawings were to be handed over independently of the signing of the appropriate contract. The plans and blueprints were forwarded to Kiel for shipment, but did not arrive there before 15 March. Transportation to Japan, therefore, is very unlikely."

Which would be tantamount to scrapping and restarting the entire SR-72 effort.

So yeah, very much nudge-nudge-wink-wink-saynomore there.

Odd given that Aerojet already confirmed that it's Aerojet propulsion on the plane.

I imagine REL are angling to replace them.

I search the cutaway drawing of SAAB J-29 "Tunnan" for retoched....!

Thanks, Motocar
Paladin's developments are great for rapid sustained fire technology that Crusader started realizing  but a Strategic Strike Artillery appears needs Light Gas and tanks need an ETC as railguns are still very risky and were judged back in the 80s as impractical for tanks.

That page has some major misinformation on it.  The statement that the XM360 uses ETC is simply false -- it's just a lightweight 120mm firing the same ammunition as the current 120mm tank guns.
