An illustration of the proposed RF-4X from the early 1970s. This was to be a highly modified version of the F-4E Phantom II capable of attaining Mach 3 for short periods. This would be possible by used more advanced inlets with water injection for pre-compressor cooling. The water would be stored in conformal tanks above the fuselage. The RF-4X would be a recon platform for the Israelies, sort of a low-budget, less stealthy SR-71.
More on the RF-4X HERE.
A fighter design from ~1990 could take off in under 600 feet, land vertically, carry two AMRAAMs, two ASRAAMs and one 20mm gun and 500 rounds. Used a remote augmented lift system for VTOL thrust, weighed about 28,000 pounds.
Silent footage of the XF-88 modified as a turboprop aircraft, rather than the standard put turbojet. The prop at the nose could be disengaged and feathered, as is shown clearly here. The idea was that at the time turboprop aircraft had substantially greater range than turbojets, which drank their fuel with abandon; the blades of this propeller were designs so that the tips would actually break the sound barrier. The hope was that a fighter could be designed to be both fuel efficient and break the sound barrier, but the sound produced by the supersonic propeller was so horrifically loud and screechy that it caused physical injury to ground crew. The idea obviously was not adopted.

A potential followup to THIS POST seems to show a better view of what may be a new stealthy aircraft:
A tiny amount of processing gives this:
To me, this might be a B-2, The underside of the “nose” certainly looks like the complex contouring of the B-2. But the trailing edge *looks* unlike the B-2. Another sites’ attempt at processing gives an interesting trailing edge:
If this is accurate, the aircraft looks like nothing so much as the Boeing Model 988-122, one of a series of stealthy and semi-stealthy highly maneuverable multi-role aircraft designed around 1996:
Remarkably low stall speed as well.

Appears to be the mockup/radar test model of the British Aerospace “Replica” concept from the late 1990s, which in turns seems to have been based on the McDonnell-Douglas JAST (Joint Advanced Strike Technology) concept which competed and lost against the Boeing X-32 and Lockheed X-35.
Around 1990, the US Navy considered an F-14 replacement based on either the F-22 or F-23 designs, the Navy Advanced Tactical Fighter (see Aerospace Projects Review issue V3N2 for a whole lot on the Northrop NATF-23). The Lockheed NATF-22 designs seems to have never been fully nailed down, but instead was constantly in flux. But the basic idea was that it would be a navalized version of the F-22 with swing-wings akin to those of the F-14. However, the Navy gave up on the idea in 1992.

Side note: if anyone might happen to have good data on the NATF-22 (more than the stuff that showed up in magazines and such at the time), please contact me.
For the next few days blogging might be a bit sparse as I work on the next issues of Aerospace Projects Review and US Bomber Projects. Usually when I release one of these, I get a *few* emails, generally complementary, sometimes asking for clarification or pointing out editing/spelling errors, that sort of thing (and with APR, “make go more faster”). I very rarely get “why don’t you include this” or “why don’t you do that” messages. Well… discuss. What would you like to see new and/or different in APR and/or USBP?
Also: the perpetual problem I have with both of these is lack of public knowledge of these titles. Heck, when I did “The Space Show” interview two months ago, I expected a slight bump in business… but sales (and views of the APR blog) actually went *down* slightly in the week afterwards. Damned if I can figure that out. So if anyone has any suggestions on how to get some press for these little endeavors, I’d appreciate ’em. And of course, an increase in interest & sales will mean an increase on *my* part in producing these things faster, so if you want APR and USBP issues at a faster clip, here’s how to get it done.
A North American Aviation concept for a highly modified P-82, dating from 1949. The piston engines would be removed and replaced with Allison XT-38 turboprops. The engines would be located mid-fuselage, necessitating that the cockpit would have to be moved well forward of their normal position. The end result would be a plane that weighed the same, gave the pilots better views and went substantially faster.
This one may show up in a future issue of USBP, as the intended role was ground attack.
Possibly an ATF, more likely a pre-ATF concept. Looks high performance but with little effort at stealth.If the code scribbled on it means what I think it might, it may be dated 1971. In which case this would be a bit late for the F-15 program (McD was picked in 1969), and certainly doesn’t fit the F-16 profile.
Another from the stash of largely-Grumman concept art, a lift-fan equipped VTOL aircraft, probably a ground support plane. The terrain is clearly Viet Nam inspired, so I’d put this in the second half of the 1960’s.
Note the complete lack of markings. This may indicate that the painting was photographed while still in a “neutral” stage, where markings could be applied aimed at specific customers. The Marines would seem an obvious choice, but in the mid 1960’s it was still a believable possibility that the Army could be equipped with aircraft such as this.
