I was sent this photo of a large scale model of the North American SM-64 “Navajo” two-stage cruise missile. the model, largely made from clear plexiglas, was some years ago on display in a Quonset hut at the Planes of Fame Museum in Chino, California. Sometime after this photo was taken the museum was shut down, reworked and re-opened, and after that the museum was no longer in evidence. The photographer wishes to know what became of this model. Anyone know?
For some years I have been operating the “Aerospace Projects Review Patreon” which provides monthly rewards in the form of high resolution scans of vintage aerospace diagrams, art and documents. This has worked pretty well, but it seems that perhaps some people might prefer to sign on more directly. Fortunately, PayPal provides the option not only for one-time purchases but also monthly subscriptions. By subscribing using the drop-down menu below, you will receive the same benefits as APR Patrons, but without going through Patreon itself. The APR Patreon itself will continue; this is just an alternative for those who wish to go a different route.
The Shuttle-C of the late 80’s/early 90’s would have carried a whole lot more to orbit than the Shuttle Orbiter, but would not have been quite as capable of precise maneuvering as the Orbiter. Consequently, it might get close to a space station, but it would be unlikely to dock with it unless it was moved into position with secondary orbital maneuvering vehicles or grabbed with manipulator arms. This artwork depicts a Shuttle-C standing off some distance from a space station, with the cargo being shuttled over with an OMV.
The Shuttle-C was described and illustrated in US Launch Vehicle Projects #4.
A NASA model circa 1959 illustrating the general configuration of a nuclear-electric spacecraft for the exploration of Mars. While apparently not meant to represent a serious design proposal, the general configuration is much the same as those created decades later. It features a nuclear reactor at the nose, a long boom with a pair of radiators to get rid of the heat produced by the reactor, and payload at the tail. Payload includes crew areas and an indistinct lander. The ring at the rear is the “propellant accelerator,” which is not described; presumably it is a structural ring holding a bank of ion engines or the like.
Note that the radiators are tapered. This is common in such designs: the gamma ray and neutron shields behind the reactor only block a relatively small portion of the emitted radiation. The radiators fit within that shadowed cone; if the radiators projected out into the unshielded volume, not only could the radiation do some damage to the structural materials it would also heat them up… defeating the whole point of radiators.
This basic layout would still be applicable today, with the main difference being that the engines might well be located elsewhere, firing in a different direction. The reactor could well be at the tail; leaving the engines where they are would turn the long boom into a structure in tension, meaning that the reactor would be “hanging” down. This would be structurally more efficient… after all, the reactor could certainly hang from a string, but a ship could hardly push on a string. Or the engines could be located near the ships center of gravity, firing “sideways.” This would be trickier for the boom, but if the engines are indeed low-thrust ion engines, the forces involved would be almost negligible. Or with a similar arrangement the ship could be made to tumble end over end; with the engines at the CG they could continue to fire “sideways” while the crew enjoyed at least some measure of artificial gravity.
In the late 1960’s H.H. Koelle of the Technische University Institut Fuer Raumfahrttechnik in Berlin devoted considerable effort to studying a reusable heavy lift launch vehicle. A good, well-illustrated report was put out in 1968 covering the design:
Note that the Neptun was *gigantic.* It was a two-stage ballistically recovered design, unusual in that rather than being circular in cross-section it was hexagonal. The individual propellant tanks were each the size of or bigger than the S-IC first stage of the Saturn V.
A number of payloads were proposed. One was a sub-orbital intercontinental passenger transport, The passenger “capsule” would land separate from the Neptun itself.
One of the more interesting payloads contemplated was a large Orion nuclear pulse vehicle, transported in two pieces (propulsion module in one launch and payload/pulse units in the other). Presumably this would be a NASA Orion hitching a ride on a West German booster; I suspect politics would have negated the likelihood of the West Germans developing a mass production line for nuclear explosives.
This fusion-powered interplanetary spacecraft is also a NASA design, dating from the early 1960’s.

A 3D CAD model currently being constructed o the Rockwell “Star Raker.” This is being done in order to nail down diagrams and artwork for a future issue of US Launch Vehicle Projects… and also possibly to serve as the basis of a 1/288 scale model kit.
A magazine ad from 1963 showing the S-IV stage and the X-20 Dyna Soar. The Dyna Soar is shown without its adapter section and Transtage, indicating that it is approaching re-entry (note that it is shown with the canopy heat shield still in place). The Saturn S-IV stage, used on a few Saturn I launches, was smaller than the S-IVB that was used on later Saturn Ib and Saturn V launches, and used six RL-10 rocket engines instead of the S-IVB’s single J-2. Also note the three prominent “ullage rockets” sticking out from the base of the stage. These were small solid rocket motors that would impart a slight forward acceleration to the stage prior to the ignition of the RL-10’s. The acceleration would be high enough and last long enough to settle the propellants into the rears of the tanks. Otherwise the liquid propellants would float around in microgravity and might very well not feed properly into the plumbing system; if a turbopump swallowed a large bubble of gas rather than liquid, it could be destroyed.
The Saturn I/S-IV never launched an actual Apollo CSM, but only boilerplate test articles. Interestingly, the BP-16 test article, launched May 25, 1965, stayed in orbit until July 8, 1989.
A design circa 1970 for a Lockheed lifting body space shuttle concept. This design was derived from the earlier STAR Clipper stage-and-a-half design from the late 1960s… the whole story of the STAR Clipper and its many derivatives is given in Aerospace Projects Review issue V3N2, available HERE.
Note that this vehicle is equipped with sizable internal propellant tanks. As a result the cockpit is separated from the payload bay; in order to access the payload, the crew would need to pass through a long, narrow tunnel not unlike that within the B-36 bomber.
A Dow Corning magazine ad from late 1969 by famed and prolific space artist Robert McCall illustrating a nuclear-powered artificial gravity space station. It’s a nifty painting, the original of which was apparently given away in a contest; all entrants were apparently given a full color print of the artwork.
In 1972 Bell designed a STOL jet transport, a concept that competed for the Advanced Medium STOL Transport role that the McDonnell-Douglas YC-15 and the Boeing YC-14 were built for. The Bell aircraft appeared to be largely conventional in layout, but it was actually quite different from every other transport: the engine nacelles were not only fitted with Harrier-like thrust vectoring nozzles to redirect the core exhaust, the flow could be diverted from the fans to augmenters in the wings. These, it was hoped, would greatly increase static thrust, allowing the aircraft to lift off from unimproved runways in a short distance. As part of their proposal, Bell also designed a proof of concept demonstrator to be built from parts of a C-130. The demonstrator could itself be used as a fair cargo transport, though of course it would not be as well optimized as the all-new vehicles. Unfortunately, the augmenter-wing concept for vertical thrust turned out to be a major disappointment as it steadfastly refused to scale up well.
The demonstrator was recently diagrammed and described in detail in US Recon & Research Projects #03, and the operational version in US Transport Projects #08.
