I’ve just uploaded a 1986 article on the “Midgetman” road-mobile Small ICBM developed but not deployed by the US at the end of the Cold War to Dropbox for above-$10 APR Patrons/Subscribers.

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.

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.

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…

My next book, released for pre-order and to be shipped in a few weeks:

US Supersonic Bomber Projects 2

“The threat posed by the Soviet Union throughout the postwar period coincided with an explosion of innovation and can-do attitude among America’s aircraft manufacturers. Challenging requirements and experimentation resulted in a huge variety of designs for aircraft powered by nuclear reaction, aircraft capable of flying faster than Mach 5, advanced bombers able to land and take-off from the surface of the ocean, VTOL fighters and bombers, and many others. Aerospace engineer Scott Lowther collects some of the most radical and beyond-the-state-of-the-art ‘secret projects’ in this – the second volume of his US projects series.”

A 1950’s film describing the “Lobber” rocket from Convair. This was a small battlefield cargo delivery system… rations, medical supplies, ammo, that sort of thing. Kind of a neat idea, but obviously it didn’t go into service. The ability to launch 50 pounds of stuff eight miles just wasn’t that spectacular when cargo planes could para-drop tons of stuff hundreds of miles away, when choppers could zip in and out in the time it would take to pack stuff into the rocket. Today i imagine drones would take on the task… not as fast, but less harsh on the cargo and much more precise.

 

Note that it is also described as a system capable of delivering *nukes.* Well, any rocket that you can swap out the payload could be a nuclear delivery system if it’s got the capability. Fifty pounds just barely covers it. It would be safer for the launch crew than a Davy Crockett with a range of only a couple miles, but 8 miles is still pretty close. The W54 warhead weighed right about 50 pounds and could yield up to about one kiloton. Eight miles would be a safe distance… so long as the fallout didn’t rain down on your head.

The “Enzmann Starship” is named after Robert Enzmann, who “designed” it decades ago. Just exactly *when* has been an issue of some confusion in recent years.

It first came to light in the late 60’s or early 70’s, with claims that he thought it up around 1964 or so. The design is unique: a giant spherical ball of frozen deuterium fuel at the front, followed by a cylindrical ship, ending with a series of Orion-style nuclear pulse engines. It was an *ok* concept for a practical starship, though relatively recent analysis presented in the Journal of the British Interplanetary Society argued that it was not nearly as good as imagined. It became something of a sensation in the 70’s after appearing on the cover of “Analog” in 1973.

Nothing has ever been produced, so far as I’m aware, backing up the concept with any sort of detailed design of analysis until that JBIS paper. No reports, proposals, pages of math, from Enzmann seem to be available… just text descriptions of a few sentences and some art. And that’s fine. But in recent years the claims have become more and more expansive. Enzmann, near the end of his life, claimed that the design for a nuclear-pulse vehicle dated not from the time of the Orion program, but back to the *40’s*.

I spoke to Enzmann on the phone a few times over the years. He was enthusiastic, verbose… and baffling. He made lots and lots of claims about having worked on this or that amazing program, but when asked for verifiable details… it was classified. Those who have picked up his mantle and are trying to carry his torch seem to be following in his footsteps there, continuing his claims without much apparent criticism. I’ve recently engaged their twitter contact to get some sort of verification of his claims… but we have now reached the point where not only am I convinced that no such evidence will be produced, I feel no reason to assume anything remarkable is true at all. Behold:

Claiming that nuclear powered aircraft were actually built in the fifties and then buried in a mountain? Yeah… no. I’m out.

A bit short of a week ago I posted artwork of a “Boeing Advanced Fighter.” This led to the re-discovery of the actual model number 987-350 (I knew it some time back, but my brain is full I guess). And that led to the below CAD diagram, coming in just under the wire for a forthcoming book. The 987-350 was a tactical supercruiser; armament is unfortunately left a bit vague in the available documentation. The artwork depicts it with four folding-fin AGM-69 SRAM missiles; another diagram depicts it with two larger-diameter missiles of similar length. All were to be semi-submerged for low drag.
