I’ve just uploaded a 1986 article on the “Midgetman” road-mobile Small ICBM developed but not deployed by the US at the end of the Cold War to Dropbox for above-$10 APR Patrons/Subscribers.
This is of course on top of the monthly rewards packages and the “Extras” posted rather irregularly. If you’d be interested, consider subscribing:
In 1992 NASA had a flurry of PR about the “First Lunar Outpost” concept which would see the US return to the moon using large lunar landers launched by a single Saturn V derived heavy lifter. A fair deal of concept art was released; much of it used the relatively new technology of computer generated imagery. Five of these images recently appeared on ebay as 16X20 prints; what the heck, I went ahead and bought them. They arrived today and I was pleasantly surprised at the production quality. They weren’t simply printouts glued to cheap foamcore, but instead are very glossy, hard plastic bonded to higher quality foamcore.
I believe I’ll have these professionally scanned and made available to APR Patrons/subscribers.
With all the little publications I’ve written and illustrated, and all the years of blogging ABSOLUTELY BRILLIANT political opinions and the like, it seems that at least *one* of my efforts will go down through the ages: my design for the Orion Battleship. We know to a fair certainty that such a craft was designed in the early 1960s, and that a mockup the size of a car was built; we know some of the components and features of that design. But other than that… we don’t know much. The overall size and configuration are unknown. So, fifteen years ago when I was working on an article for Aerospace Projects Review about large Orion vehicles, I went ahead and made a speculative reconstruction design. I did my best with what was available… and in the years since, nothing seems to have come out to refute the design. I do not contend that the design is an accurate reconstruction; I was never able to get in touch with anyone who knew the Battleship design first-hand to confirm my reconstruction. I could well be *badly* wrong, especially since the descriptions of the original design tend to be second-hand. One day we might find out for sure.
But in the years since I showed my design to the world, I’ve seen it recreated here and there. It seems to be the accepted Actual Design.
Huh.
Behold:
That second video uses a model based on my design, more renders of which are HERE.
A purchasable 3D printed, lower fidelity copy of my design on Etsy:
My renders – unimpressive even by 2009 standards – even made it into meme format:

There are several ways to accomplish the goal of extracting maximum performance from a solid rocket motor via the nozzle. The most common way – a convergent-divergent nozzle – is the standard for a reason: it’s the simplest, lightest most reliable way to do it. But there are alternatives that provide specific advantages. One of them is the “forced deflection nozzle.” Instead of a single circular throat, the nozzle has several; instead of directing the exhaust gas due aft, it forces it “sideways” to smack into the broader, shallower nozzle.
The advantages here:
1: The nozzle is sort of a hemispherical bowl, rather than a long, slim cone or paraboloid.
2: It provides some altitude compensation, similar to an aerospike.
There are also disadvantages, not least of which is that the throat is now under substantially greater thermal and dynamic forces. Few materials known to Man will be able to long withstand the high heat load and erosive forces. But in 1986, Aerojet proposed to develop such a nozzle for a singular purpose: to integrate into future ICBMs. The reasoning was… the bowl-like nozzle fits the bowl-like forward dome of the lower stage. Instead of a long interstage structure being required, the stages fit together neatly. in principle this would allow ballistic missiles to be more compact, shorter by useful distances. This is not very important for space launchers, but for missiles that need to fit into silos, submarines, bomb bays or Shuttle cargo bays, extra space means extra capacity.

You could have a much shorter vehicle with equivalent weight and payload, or same-length boosters with 28.4% greater range for the same payload, or 33% greater payload for the same range.

Here’s something you don’t see too often… someone firing *numerous* rounds from a Gyrojet. Each of these .45 caliber rounds are solid propellant rocket units, last manufactured in the 70’s or so. They apparently run about $200 *each,* which makes me wonder if there might be a market for newly manufactured ammo. As a practical home defense, police or military weapon… the Gyrojet basically wasn’t. It took something like 50 feet for the round to reach maximum velocity, which means at close range it might just bounce off an opponent. But as a range toy they might be fun, especially if the cost per round could be dropped substantially. And there’s no reason why it can’t… sure, each round is more complex than an equivalent conventional bullet, but they are just some basic parts with 1960’s rocket propellant. And that last could doubtless be improved; better propellant, better grain design and better manufacturing of the nozzle plate could *really* boost performance.
The claim is made here that the Gyrojet was designed to be used in space because they were uncertain if conventional gunpowder firearms would work in a vacuum. This is untrue; nobody with the least bit of understanding of the chemistry of gunpowder and how guns work thinks that guns *won’t* work in space. However, conventional firearms do have three major issues for space applications:
The Gyrojet has far lower recoil than conventional firearms. And the Gyrojet is a far simpler mechanism, made largely from stamped metal sheet to far lower specifications. This means it can heat up without jamming, with virtually no need for lubricants. So the Gyrojet seems like it’d make a dandy sidearm for the USSF. Bump it up to .75 caliber and you have yourself a light bolter. And perhaps best: home manufacture of Gyrojets would be *easy.* A 3D printed Gyrojet, with some *basic* metal parts, would not only be easy to make, but with vastly lower forces imparted on it than a conventional firearm, it’d be far less likely to explode.
So… where are the new-manufacture Gyrojet rounds? At $200 a round for the vintage stuff, you can start off *real* expensive and still undercut the current market.
Recently acquired at some cost, and finally fully scanned at some effort, is this 1965 “Master Plan” for Kennedy Space Center. It’s basically a book of maps of the region showing all aspect of the infrastructure. It’s in good shape and was scanned at 600 DPI rather than the usual 300, due to the fine quality of the maps. It will be in the next catalog for Patrons and Subscribers to vote on. It’s a little out of the usual for APR… it’s not about unbuilt aircraft or spacecraft; in fact, no aircraft or spacecraft designs are included. But it’s still an interesting historical artifact.
I also have a KSC Master Plan from the Shuttle era. Substantially larger format, with more conventional full-color maps. I haven’t scanned that due to the chore it would be to get done, but if this proves popular, I’ll get on it. I *also* have a large-format Master Plan for Ames Research Center.
If you are interested, check out the Historical Documents Program.
I put one copy of each of my current books on ebay. They’re all in brand-new condition, and will be signed/dated when sold. They also come with bonus 18X24-inch prints… the “SR-71” book has two prints of the SR-71, the “B-47/B-52” book has one B-47 diagram and two B-52 diagrams; “US Supersonic Bomber Projects Vol. 1” has two B-70 Valkyrie diagrams. Take a look…
My next book, released for pre-order and to be shipped in a few weeks:
“The threat posed by the Soviet Union throughout the postwar period coincided with an explosion of innovation and can-do attitude among America’s aircraft manufacturers. Challenging requirements and experimentation resulted in a huge variety of designs for aircraft powered by nuclear reaction, aircraft capable of flying faster than Mach 5, advanced bombers able to land and take-off from the surface of the ocean, VTOL fighters and bombers, and many others. Aerospace engineer Scott Lowther collects some of the most radical and beyond-the-state-of-the-art ‘secret projects’ in this – the second volume of his US projects series.”
