So I backed off blogging so much because yapping on Twitter was so much easier. But then…

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.

The USSF wants to actually be able to do their job. Could we see the return of the heady days of the Star Wars program? Now that we have actual almost-affordable and mostly-reusable space launch, we just might. Get ready for the pages of Aviation Week to be filled with artists concepts of space based lasers, neutral particle beams, orbital and cisluanr assets of all kinds. Can we even dream of manned nuclear powered spacecraft patrolling the spacelanes?
Of course, a lot will depend on November.

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.

A reminder that at o-dark thirty tomorrow morning, SpaceX will, hopefully, launch the first all-private manned orbital mission. It’ll be the highest humans have orbited Earth (discounting Apollo astronauts who broke Earth orbit to head to the Moon), and will include a spacewalk with new spacesuits. Currently scheduling 2:38 AM central time.

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 miss having neat nature to take photos of. Utah was full of that. Illinois… well, it’s here, but usually obscured with buildings, power lines, light poles, etc. Still, every now and then something worth taking a photo of emerges.

Oh, Fᚪᛣᚳ…
Maybe it’s the Old Guy in me, but this set off every alarm bell I have. Maybe this sort of thing would be good for people with serious mental issues, but for regular people? I can’t foresee anything but Black Mirror horrors. Replacing jobs with AI is bad enough; replacing human interaction with AI gives me an uncomfortableness I cannot begin to explain.

The first metal minis – 1/144 X-20, 1/285 X-20, 1/285 XF-103, 1/285 XF-108 – have been cast, cleaned and assembled. I’ve got enough to take care of the existing crowdfunders; I plan on trying to make a go of the 1/285 X-15s as well. However, the main mold is already falling to bits, so there are still improvements to be made to the process.
For future versions… should I cast them with a “peg hole” in the underside to put on a standard stand, or just leave them as they are?
