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.

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.

The SST designs of the 1960’s are hardly unknown. But what’s generally not well understood is that designs such as the Boeing 2707 were *huge.* This was considered necessary because SSTs with fuselage lengths in line with existing jetliners – such as the Concorde – would have small passenger capacities due to the need for the fuselages to be *very* narrow compared to their lengths. This, as Concorde showed, was a great way to build an extremely cost-ineffective fuel hog.

So the 2707 would be terribly long and pointy, with a geometry quite a bit unlike regular jetliners. A practical concern is “how do we deal with these things at airports?” If nothing else, the long pointed nose of the SST would put the passenger door considerably further aft than for a conventional rounded-nose jetliners. So, like the 747 and the A380, it was assumed that the larger airports would have to make some infrastructure modifications in order to deal with these new beasts.

The illustration below, from a 1967 issue of Aviation Week, shows American Airlines thinking about the airports of the future. Note that the 2707 is pulled in far closer than the other craft, with the tip of t’s very pointed nose just a few feet away from the building while the others are notably further away. The SST is being serviced by two extendable jetways at maximum extension, while most of the other planes seem to be getting along with just one jetway… though one of the 747s is using four. Note that even though the 747 isn’t pulled in quite as far as the 2707, the SST nonetheless projects much further out into the airfield. For some airports this could well have meant that the taxiways would have been a cluttered mess.

A while back a 1987 press image was posted on ebay showing a McDonnell-Douglas full scale mockup of a Neutral Particle Beam weapon system. This would have been an experimental system, not an operational weapon; details on full-scale NPB weapons are *very* hard to come by, but the smallest NPB weapon system that I’ve seen anything remotely resembling hard data on would have required a non-trivial number of Shuttle-derived heavy lift launch vehicles to put into orbit a piece at a time. Some references – extremely vague ones – have even made mention of dimensions for the full-scale weapons being measured in kilometers.

The purpose of this system would likely have been to simply show that a neutral particle beam could be reliably generated and directed at an orbiting target some decent distance away. While it would likely be very unhealthy to be int he way of such a beam, it’s weapons potential would doubtless have been low… thus the need for vastly scaled-up operational versions.

The 1969 movie “Marooned” featured an Apollo crew stranded in orbit and eventually rescued by a lifting body spacecraft,the fictional “XRV.” It has been noted that the vehicle and the basic setup look a *lot* like an illustration from a 1965 issue of Aviation Week depicting a Martin Co. lifting body rescuing the crew of an Apollo spacecraft:

 

There is clearly something a little strange going on in this artwork: what may seem like an adapter section or a propulsion module behind the lifting body is actually a docked Gemini spacecraft. There is no explanation for this, but I can speculate. The lifting body is meant to serve as a rescue craft, so it would need to have as much internal space as possible. Not just for three rescued Apollo astronauts, but three astronauts potentially in medical distress. So they might need to be laid out on stretchers, not just sitting in seats. Consequently, while they would need a pilot to get them home and “ambulance staff” to get them squared away, there might not be enough room for everyone. So *perhaps* what’s going on here is that the spaceplane is launched empty or with just a pilot, and the Gemini/Adapter has two EMTs in it. They get the rescuees  dealt with and sent home, and they come home in the Gemini. This way, three rescuers go up, but only one comes down taking up space in the lifting body. This is non-optimal, of course; better would be to bring everyone home in one large vehicle. But perhaps this was the best that could be done with the intended launch system, presumably a Titan IIIc.

The lifting body is clearly related to the X-23/X-24 geometry that Martin was beginning to study at the time. A mockup that is very similar, though with the central vertical stabilizer that eventually appeared on the X-24, is shown HERE and HERE.

In June 1973 Rockwell put together a short course – presumably or employees new to the STS program – that described the Space Shuttle system as it was then designed. There were a number of clear differences between the STS of the time and the STS as actually built. Differences included a forward extension of the OMS pods, continuing well onto the cargo bay doors. Also, the forward RCS thrusters on the sides of the nose were contained behind sizable doors to protect them during re-entry, a protection that was found to be unnecessary. There were also important differences with the SRBs and ETs.

This is what a manned mission to Mars dating from the late Apollo era would have looked like: a cluster of hydrogen tanks with a small number of NERVA nuclear rockets. The spacecraft would have been relatively gigantic as it leaves Earth orbit; large enough that it would have been assembled in space from at least six Saturn V launches. When it returns to Earth it would have been little more than the mission module; this would blast past Earth and continue in solar orbit while the astronauts and a few trifling hundreds of pounds of Martian souvenirs  would have plowed into Earths atmosphere in a compact entry capsule. The mission module itself is described fully and heavily illustrated in US Spacecraft Projects #3.
