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.

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.

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. If interested in this or if you are interested in helping to fund the preservation of aerospace histgory, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.

A late 1950’s project from Fairchild Aircraft for a STOL aircraft, the M-232. The propulsion system was fixed, but the wings were given large flaps that would direct the bulk of the propwash more or less downwards. Coupled with the extreme nose-up attitude on the landing gear, this would almost be enough for vertical takeoff and landing. An aircraft like this would be used in a role much like that of the OV-10 Bronco.

This came from a series of articles that have been scanned and made available as “Extras” to APR Patrons and subscribers at the $11 and up level.

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.

A sad percentage of my cyanotypes fail… faded, blurry or spotty. Sometimes these failure are due to bad craftsmanship; sometimes to material deficiencies, and surprisingly often, environmental factors (humidity has wreaked havoc, see the “spots”). Mostly these get simply tossed, meaning a lot of material, time and effort are wasted.

But it occurred to me that while they’d stink as proper blueprints, they might make dandy giftwrapping paper. So I’ll try that. I’m thinking of ebaying this lot of A-12 diagrams. These are all about 24X36 inches. Five sheets; if these were all successful, that’d be more than three hundred dollars worth of blueprints. Obviously not worth that, some fraction. And instead of being mailed rolled, they’ll be simply folded and sent in a padded envelope. If interested, send an email. If I get an offer that overcomes my depression at the failure these otherwise represent, that’d be great. Otherwise, ebay.
