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.

1/18 scale Skybolt ALBM kit

Aug 192024

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’ve shut down production of cyanotype blueprints for the time being. What I’ve got is what there is; I’ll leave the catalog page up while I still have a supply, but I’ll shut it down when I run low and sell the rest on ebay. Get ’em while ya can.

Martin-Marietta HML Ad

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:

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.

Orion Space Battleship

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.

Forced deflection nozzles for ICBMs

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.

Diagram showing a conventional 3-stage solid rocket ICBM against three concepts making use of the forced deflection nozzle. 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.

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…
