Rumored and discussed for years, in 1962 General Atomic reportedly built a “Corvette sized” display model of the 4,000 ton Orion spacecraft as a spacegoing battleship. This model was shown to President Kennedy, and the reported reaction was… not great. The model was described by a few who had seen it, but all evidence of the model vanished, with the presumption that the model itself was either destroyed or lost, probably shut in a crate next to the Ark.

Well over a decade ago I took those scraps of description, coupled with random bits of data, discussions with a few who knew things, and some imagination, and pieced together my own interpretation of what the Orion Battleship may have looked like.

Some printouts of my diagrams, years ago:

Somewhat to my surprise, my diagrams have been spread far and wide and have become the de facto canonical image of the Orion Battleship, with sketches, 3D CAD models, paintings, etc. being made based to greater or lesser degrees on my design. My one real contribution, I guess. I’ve never tried to claim that it was accurate, just that it was the best that I could do with what I had. I never expected to be able to do better.

But then author Brent D. Ziarnick published the book “To Rule the Skies” in 2021. In it was, at last, a photo of the model. While the book was published 3 years ago, I only stumbled across this image today:

There are *clear* differences between the model and my interpretation. Mostly they involve the means of projecting the pulse units: I based my design on the system used for the 1963 4,000 ton Orion: a cannon along the ships centerline that shot the pulse units directly aft through a central hole in the pusher plate. But the model depicted an older, more cumbersome approach: those “fins” on the side are actually rails. They’d lob the pulse units past the edge of the plate. I now this because circa 2009-12 I communicated with Jim Bryant, who was an artist at General Atomic and he created a sketch for me of Orion as he knew it at about the time the model was made. From his sketch I created CAD diagrams:

You put my two diagrams together… and you get pretty close to the configuration shown in the model.

I’ve got high hopes for getting an improved-rez version of the photo (maybe more!). I will use that to create a new set of diagram, probably also a 3D model, of the *official* “Orion Battleship.”

I don’t feel too bad about getting some things dead wrong. The Orion concept was in serious flux at the time; had the USAF proceeded with the battleship, it would *not* have used the pulse unit “fins.” Instead it would have evolved to something like what I drew up. It could well have evolved *past* what I drew up, but that’s a question that can only be answered in an alternate reality.

A scientific paper published more than 20 years ago was recently rediscovered by the internet:

Sugawara et al. 2003, “Destruction of Nuclear Bombs Using Ultra-High Energy Neutrino Beam”

https://arxiv.org/abs/hep-ph/0305062

A lot of this goes over my little post-Covid head, but the summary seems to be that, theoretically, an advanced high energy collider, similar to but larger and more powerful than the Large Hadron Collider could slam muons into each other and create a laser–like beam of neutrinos. OK, cool. But where I get fuzzy is the discussion of the “mean free path” of the neutrinos. By tinkering with the exact energy of the neutrinos, you can set the MFP to the exact distance from the collider to the target. The beam of neutrinos pass virtually unhindered through the Earth, then, at a fairly specific spot, they create a shower of hadrons. That’s where I’m lost: do the neutrinos suddenly decide “ok, let’s interact with the atoms in dirt right here,” or what, exactly? I’m puzzled.

But in any event, that shower of hadrons *is* perfectly capable of interacting with normal matter, such as the fissile material in a nuclear bomb. In a matter of seconds or minutes, the uranium or plutonium will heat up enough to cause the surrounding high explosives to catch fire or detonate, while messing with the nuclear properties of the warhead itself. They estimate that the bomb will “fizzle” with about 3% the yield it was designed for.

The anti-weapon weapon is hilariously impractical: even with advanced superconducting electromagnets the collider will be on the scale of kilometer in size, costing hundreds of billions. Each shot will require the power output of a nation, and will only target a single nuclear weapon, whose position must be known to just a few feet. And it kinda seems like this vast ring-like structure must be aimed physically. Good luck with *that.*

It seems like “physically possible, engineeringly impractical, financially impossible” project. Something nobody could pull off on Earth. On the other hand, the sci-fi possibilities are clear. Aliens, say, show up. Their scouts check out Earth, realize we’re loaded with troublesome nukes, so their von Neuman bots start carving up the moon. They dig a trench around the moons equator and fill that trench with a vast accelerator… with the reaction chamber pointed right at Earth. A relatively small jiggering of the chamber can aim the resulting neutrino beam to any desired spot on Earth; slight adjustments to the colliders power sets the precise range. Nukes in solos start melting down. Nukes on planes kept in constant motion, however, would likely be safe. Nukes on subs? If they can precisely track submerged boomers, they can probably target them.

Here’s the first nearly complete set of “sellable” 1/18 scale Skybolt ALBM parts. Only things missing are a stand(s) and a clear cover for the star tracker. There’ll be 2 variants… complete, and a simpler one without most of the innards (build with the stages/warhead joined). It takes about 2 *days* to print a complete set of parts. I’m still pondering the price. I will probably start on the low end and raise the price as I realize just what the frak I’m doing. Probably something along the lines of $80-$100, + postage. If interested, let me know.

I did my best to stitch together this two-page magazine ad. Dating from 1986, it shows missile programs then underway at Martin-Marietta; front and center is the Small ICBM (“Midgetman”) in its Hard Mobile Launcher. The HML would wander seemingly at random around the western US, being difficult to track and target by the Soviets. When the time came, the trailer would be dropped off and the suspension collapsed to lower the trailer to the ground; sloped shells would drop to the ground. In the event of a nearby nuclear detonation, it was hoped that the shockwave would roll over the shell without excessively damaging the trailer. Then the missile launch tube would be raised and the missile fired, sending a single warhead across the planet. The tractor for this version was designed and built by Caterpillar and used rubbed treads, unlike the wheeled Boeing competitors.

So after having the 3D printer for a while and running a *lot* of resin through it, I have achieved some good things. I’ve learned enough to know that there are some things that I plan on producing as full 3D-printed kits, some to be converted into metal castings. I have a few product lines that I want to do:

1: 1/285 (wargaming scale) “minis” of a range of appropriately sized unusual, rare, interesting and projected aircraft/spacecraft

2: “Mini”-sized, but of various scale, aircraft and spacecraft to go with each issue of US Aerospace Projects

3: 1/18 scale models of each American nuclear bomb/warhead/re-entry vehicle. This will range from the downright dinky to the “I’m not sure how to squeeze this out of the printer,” like the Mk 17 and the Flashback. I’ve successfully printed prototypes of the Fat Man and Little Boy A-bombs in 1/18, but they need to be revised.

4: Just whatever strikes my fancy by way of interesting aerospace/sci-fi concepts.

The eventual 3D printed kits will be pricier than if they were cast resin “garage” kits, but this will allow me to make them on demand. I hope there is interest in this sort of thing. To that end, and to help refill my depleted coffers, I’m making available a “crowdfunding” project with three levels. What you will receive are the actual 3D printed components. Each level builds on the prior… Level 2 gets you the Level 1 stuff, Level 3 gets you 1 and 2. No additional postage is required for continental US address… Hawaii, Alaska, Canada, the rest of the world, contact me and I’ll work out the additional postage cost.

Note: many of these are “prototype” kits, with revisions and improvements possible or even probable. And some of these are not planned to be released further. This will be your only chance to get them, at least in this format.

Level 1. You will receive:

1/285 X-20 Dyna Soar spaceplane
1/285 XF-103 Mach 3 interceptor
1/285 Project Pluto nuclear ramjet
1/285 X-15 set (X-15, X-15A2, X-15A3, X-15/SERJ)
1/18 Davy Crockett battlefield atomic warhead w/stand

Crowdfund level 1: $60 in the continental US:

——–


Level 2. You will receive:

1/18 US Atomic Artillery Shells w/stand
1/144 X-20 Dyna Soar
1/18 M61 Vulcan Gatling Gun w/stand
1/18 Mk 72 Nuclear Warhead/Re-Entry Vehicle

 

Crowdfund level 2: $100 in the continental US:

——–


Level 3. This part will not ship immediately, as some of it remains unfinished. You will receive:

1/285 XF-103 w/missiles
1/350 Orion Nuclear Pulse Vehicle (with stand… not yet finalized)
1/2000 Aldebaran Concept Vehicle
Cast Metal 1/285 X-20 + XF-103 + X-15 + Pluto: Depending on the success of the casting process. Not all are guaranteed.

 

Crowdfund level 3: $200 in the continental US:

1/350 War Rocket, 1/18 Pulse Units, 1/18 Atomic Artillery Shells.

 

 

The War Rocket was modified & printed from a file created for Fantastic Plastic. Their version – currently available – is in much larger 1/144 scale. I was impressed with the tiny details that this smaller print picked up, but the wings are mutated. Two have been printed, both with mucked-up wings. Another round of printing is planned with the models standing straight up to see if that fixes the issue; but since that’ll be a *16* *hour* print job, it’s a low priority.

 

 

Buttons horned in on the photography. He’s allowed. He’s old, he was unwell last night, he wanted attention, he gets it. He’s at this moment making typing a challenge for me.

 

The “pulse units” are actually failed Casaba Howitzers. The telescope components failed rather spectacularly. But with some minimal mods, they’ll make great pulse units for the 10-Meter Orion.

 

 

The 1/18 Atomic Artillery Shells have printed numerous times fantastically. They’re basically in production, but the rather simple stand I created for the set refuses to print right. Weird.

I’ve printed off two more Fat Man bombs in 1/18. I can see where improvements can be made to the CAD model, but as is they’ll build up into spiffy little pieces.

 

Right now I’ve got 2 Fat Man, 2 Little Boy hopefully to sell to help defray costs; if there is interest I can clearly print out more. If interested, let me know. I have two of each right now hopefully to sell to help defray costs; if there is interest I can clearly print out more. So… who wants ’em? $60 per Little Boy, $100 per Fat Man, plus postage.  If you want both Little Boy and Fat Man… $150 + postage.

 

If I refine these for a regular production run, there will be some changes for improved printing, some additional details and importantly stands. But “if” is doing a lot of heavy lifting, and the refined production kits will probably run 1.5 to 2 times as much. 3D printed kits provide options that cast resin kits can’t match, such as complete tail units, but they take many hours each to produce.

I’ve been running the 3D printer, with mixed results. Failures and disappointments are the fault of the CAD models; the printer itself (Anycubic Photon Mono X 6Ks) is working as advertised. Printing is not a fast process; some prints took 12 hours.

This is a little outside the usual for APR, as it is satire rather than actual aerospace design. But I thought it appropriate nonetheless; I remember dreaming up just about the exact same ideas when I was twelve. There was something about the design of those pens that just *screamed* for them to be envisioned as spaceships and missiles and whatnot.

The full-rez scan of the article, and a few more bits, been made available as a thank-you to APR Patreon and Historical Documents Program patrons at the $4 and above level, placed in the 2024-04 APR Extras Dropbox folder.

Here are some hypothetical subjects for metal casting as “minis.” I have three pages (standard 8.5X11) of diagrams, all depicting possible subjects at the size they would be at the stated scales. First page shows what I consider a number of interesting designs… not at a constant scale, but size.

 

 

 

Second page depicts a range of Project Orion vehicles again at a roughly constant size. Constant size means, hopefully, a consistent cost.

 

Third page shows two sets of 8. The US Bomber Projects #1 set has 8 bombers at roughly constant size; US Fighter Projects #1 set has the fighters all at the same scale. 1/285 at least used to be a kind of standard for wargaming, though I’m not sure how widespread it truly was.

 

Sets like USBP01 would probably all be at about the same price, but those like USFP01 might vary since some designs at quite a bit bigger. What I’m kinda hoping for is the individual minis being about $25 each, while the 8-sets be about $100 each. Thoughts?

 

These are of course not the full possible catalog, nor would all these here necessarily come to pass. And scales/sizes could vary substantially. A lot of it would depend on actually trying them and see what works, what fails spectacularly.
