Orion Battleship: found at last

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.

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.

First Metal Minis

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?

3D Printer “Crowdfund”

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:

Obviously not a lot of blogging of late. A lot of this is due to much of the function of blogging having been transferred over to my Twitter (@UnwantedBlog), but also a lot of it is due to my time having been consumed by the new 3D printer. After some weeks of tinkering with it, I’ve gotten it to reliably produce some things easily, unreliably produce some things with difficulty, and fail to produce some things whatsoever. However, I’ve gotten it to make a lot of a number of different things. So as previously mentioned on Twitter and in the Aerospace Projects Review/Unwanted Blog emails, I’m planning on doing a “crowd funding” project. I’m looking at three levels… $50, $100, $150. Each would come with a package of 3D printed projects, from 1/285 scale “minis” to 1/18 scale aircraft ordnance and nuclear weapons. The top level would also have cast-metal minis in the mix.

 

I’m working on getting it all together and hope to have it available in the next few days.

More 3D prints

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.

1/18 3D printed A-Bombs

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.

3D print results

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.

3D Printer incoming…

Apr 222024
 

I went ahead and ordered an Anycubic Photon Mono X 6Ks. The reviews are good and the price was ok; I have high hopes that it won’t be a monumental learning curve, but I guess I’ll find out. i expect I’ll be watching a fair number of YouTube tutorials.

 

The CAD models I’ve made in the past for the likes of Fantastic Plastic will in many cases not translate over directly… something made to be printed at 1/72 scale would have fabulously thin wings, say, at 1/285 scale. So few of the things I’ve already done will be directly usable. But some will. Going to have to go through my catalog-o-stuff for some first test objects. Expect to see some badly mangled Orions…

 

Financially this was probably not a great idea. So I will doubtless try to come up with something near-term as a way to “crowdfund”a  purchase I’ve already made. One thought: my plan was for “standard” metal minis in the area of $25, and a set of 8 slightly smaller minis in the range of $100-$125. So… how about for early funders, $60 gets you one “standard” and one “set,” once I get things dialed in? These items *may* be “mystery items,” or possibly a choice from a very limited preliminary catalog.

 

 

 

Something I *really* want to do: a modification set for the Tamiya 1/350 scale USS Enterprise, CVN-65. This would replace the radar on the island with the original “beehive…” and put the launch shelters/platforms at for and aft for the Pegasus troop transports. *THAT* is the CVN-65 I want next to me 1/350 NCC-1701.

Minis visualized

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.
