In praise of SMART boondoggles.

From Griper Blade, a blog I wish I'd known of earlier.

Griper Blade: Shooting Down Missile Defense: "Since Obama's election, Bush loyalists have been quietly freaking out that he may not really be willing to waste money hand over fist on missile defense anymore. The military has never been very excited about missile defense (Pentagon officials refer to civilian MD advocates as 'missile defense moonies'), so it's not like they see any worth to the systems. But those Bush loyalists sure do. And they've made repeated attempts to get you to panic at the thought of abandoning it."

A commenter wryly observes that, while utterly unlikely to succeed in shooting down missiles that are unlikely to materialize in any case, is as worthy as any other make-work program in these troubled times.

However, the end result is a great deal of very expensive and useless stuff, when for far less, we could achieve far more. I'm speaking, by the way, to people in the Canadian Parliament and defense establishment. I recall reading earlier today - and my apologies, I forget where, - that in terms of defense technology, and specifically in terms of the F22 program - that due to the usual practice of selling air-superiority technology to allies, the US (and a rather significant number of Canadian subcontractors) are, in essence, competing with themselves.

My initial thought as I closed the article was "what a stupid boondoggle."

And then, in reading this, something clicked. You see, what we need is to concentrate on intelligent boondoggles. Useful and plausible boondoggles intended to generate useful side-benefits. It's nice to have something useful at the end, but if enough useful byproducts come along the way, it may not actually matter in the end.

One absolute priority is to keep very skilled people doing fairly much what they are doing. We really do not wish to see highly skilled weapons systems designers becoming available on the open market.

From several perspectives an ultimately pointless employment that, while unlikely to produce a useful weapons system nonetheless requires all kinds of amazing and useful technical spin offs is worth a certain level of support. And, of course, it doesn't end up producing some simple, easily deployed and cheap pain in the ass - as Gerald Bull (cite above) was casually able to achieve once he was forced to - erm - set his sights lower.

So, while it might seem obvious to cancel boondoggle missile defense programs - please. Think of the Children. We truly do not want to see that staff and technology wander off into unpredictable and horrifyingly effective "practical applications" in the "real world."

More to the point, think of all that lovely technology and all those systems that have come astonishingly close to actually achieving something. Indeed, what if the effort were intentionally expanded to explore practical applications using technology already developed? What if it were adapted to several fairly important long-term priorities - clearing space junk and producing some sort of asteroid defense?

Indeed, what about using the technology to create an anti-junk defense for the international space station - which could then be refined to be applied to communications and resource satellites?

Remember that these are inherently useful goals and which will absolutely have all kinds of high-tech industry spin-offs.

This, by the way, is the primary value of Big Science efforts, like a manned Mars mission - it's not the goal so much as what needs to be figured out in order to send a man to Mars that is the the compelling argument for doing it.

Weapons programs work much the same way. One of the beautiful things about any weapons system is that it's a fairly straightforward application of technology, the R&D is covered by military budgets, and there is a simple, defined development path. That's why cutting edge applications are first seen in military use. I'm quite certain that the initial development costs for the wheel were written off by some military or another. And it was retired soldiers who spread it into the civilian world, because even a former grunt won't grunt any harder than he has to.

So what we should be thinking, as part of the entire military procurement and supply planning process, is what technologies we'd like to advance and what sorts of systems and applications we would like to familiarize soldiers with, both in terms of application and in terms of a trained first generation pool of persons directly familiar with the basic technology. It's difficult to plan for spinoff applications that arise due to the solution of problems in unexpected ways, but you will have a rough idea of the general nature of those unexpected goodies.

It's not difficult to think of several technologies that absolutely must be developed - and soon. Robust and reliable high-density batteries and fuel cells, coupled with flexible, rugged electrical generation systems that can suck energy out of whatever is available - from sunlight to sugarcane. If you think that's a silly thing, ask any field commander how much any operation depends on maintaining a fuel train. Reducing that train by even a few percentage points is an extraordinary valuable thing, and it becomes worth doing LONG before it makes economic sense in civilian hands.

But we will need them as civilian ready units. Climate change is going to increasingly impact our ability to reliably keep energy running through wires and it's going to change what gets moved from where - even if no other unforeseen emergencies occur. Developing such capabilities must be seen as an urgent, national security priority throughout the Northern Hemisphere. We are going to have to solve all kinds of logistical problems and, as a matter of practical reality, the place logistics is most universally emphasized is within the military and various Coast Guards.

And then we must look at the certainty of some degree of rise in ocean level. We absolutely must develop amphibious technologies, because many of us are going to be living in amphibious communities.

And then there's an issue that Ottawa does not seem to be taking as seriously as it deserves - the emergence of the Northwest Passage as a practical reality. Realistically, this is not something Canada can offload on other powers. Aside from issues of sovereignty, take a look at the map.

The majority of potential North American deep water ports with shortest great-circle paths from Asia are Canadian. That means the shortest path between the two single largest economic powers - the United States and Japan - is right though Ontario.

We are about to become vital to international trade, as opposed to being perepheral. And we must, absolutely, as a matter of the most elemental self-preservation, control that crossroads. It must be secure, and if we do not secure it, I assure you, someone else will.

Current projections suggest that the Arctic Ocean may well be navigable, year round, by 2013. This absolutely mandates some sort of concentration of presence there, if only for the obvious necessity for an Air/Sea Rescue capability.

We need to learn how to feed, house and support large populations up there in ways that don't add fuel to the Climate Change fire, because those populations will develop as a matter of necessity. The shortening of trade-routes is so economically compelling that Canada's only real choice here is how to accommodate it. And, seriously, we must start now.

These are things that cannot become economically viable until you figure out how to make them work well enough to figure out how they should work. This is one of the great unspoken values of military applications. And in the case of Canada, we have more high arctic terrain than anyone else. I rather think it a good idea to be prepared to provide peace, order and good government.

Otherwise, we could be doing it unprepared, half underwater, while freezing in the dark.

Navy's Unspoken Reasons for ASAT Shot

clipped from news.yahoo.com

The size of the debris is smaller than the Pentagon had forecast and most of the satellite's intelligence value was likely destroyed, Cartwright said. Though the Pentagon has played down that aspect of the shootdown, analysts had said one of the reasons for the operation was that officials worried that without it, larger chunks of the satellite could fall and be recovered, opening the possibility of secret technology falling into the hands of the Chinese or others.


blog it
Maintaining secrets is a good reason for shooting down a surveillance satellite, even if the only secret is that the intelligence it provides is no better than commercially-sourced data. (Let's hope that's not true, but given the fierce drive for privatization under Regan and both Bushes, it may be closer to the truth than many expect.)

But surely the other point to the shot was the shot itself. It seems to me that the odds that a tank of hydrazine could survive re-entry is a remote risk indeed. But even chunks of satellites can give very useful insights to people who should have to work harder for them.

Nonetheless, there is a great deal going on here that remains unsaid, possibly with the hope that the taxpayers of various nations don't quite realize what's really going on.

But the facts on the table are this: The chinese have demonstrated an anti-satellite capability, using tiny maneuverable explosive satellites that must already be in orbit to attack.

The obvious unspoken message is to the Chinese - "We can do it from the ground, and we don't need no damned explosives to send out clouds of shrapnel. We can just hit it with a goddam brick."

And all of this is very compelling, so compelling that it might well cause us to forget the fact that was used to contrive the excuse for shooting down the satellite.... that it might fall down and (gasp) HARM people!

That inconvenient kinetic truth is something that was first underlined by the Soviets, as they orbited first sputnik, and then demonstrated a capability to launch and parachute land a manned capsule that, unless I'm very mistaken, was the shape and roughly the size of the Trinity device.

Speaking of unspoken messages - inasmuch as the technology of the day required parachutes to ensure detonation at the correct altitude.

The mercury program responded using ICBM technology of the day to demonstrate first suborbital and later fully orbital capability with a manned space-capsule that bore an uncanny resemblance to the aeroshells we used for our own atomic weapons - but on a scale that would have held a weapon large enough to pave metropolitan Moscow in kimberlite.

If you want to know why we used disintegrating telephone poles instead of the far more elegant drop-launch technique with X-15 technology to put a man in orbit - that's why. We were waving our big sticks at each other.

So, the fact that things can fall out of orbital space with a loud bang has been pretty much the point to the entire enterprise for the last fifty years. The hard part is NOT making a smoking hole. And of course, not making a smoking hole within a relative degree of precision is also a desirable point to be made. If you can AVOID making a hole in the steppes or the Pacific ocean and recover the payload intact - well, you can put it into the same target zone and achieve a disturbing energy release.

Even without an atomic payload.

The term "smart crowbar" has been around since the early eighties, nutshelling the idea that a crowbar in space equaled at least one tank on the ground. And while delivering that crowbar with precision to take out a tank might have been iffy at the time - putting it within the "strike zone" required to turn an aircraft carrier into something that had formally been an aircraft carrier probably was a reasonable objective.

Given our current capabilities, I have little reason to doubt that we could deliver a smart slug from orbit through any particular compartment within a destroyer. It might even be possible with off-the shelf systems.

This capability, while unstated, is unavoidably available in a crude way with any satellite that has a sufficiently dense component and which can be de-orbited on command. As dense as, say, a thermionic plutonium battery. At least, were I designing a satellite that might have to be de-orbited, and which required such a power source, I would certainly try design it so that if it did de-orbit, I could ensure that component landed within as small a radius as possible and survived the impact without dispersing radioactivity.

And that is pretty much the design requirement of a dense slug penetrator.

Oddly enough, such batteries are designed in exactly such a way; whether they could be so exactly targeted is an open question, but the physics of the matter are pretty obvious to those who think about it.

And so the unspoken message by those interested in controlling the High Frontier - the Air Force - has been that of all the targets on the face of the globe for such a device, the highest value target has to belong to the Navy. For, while other nations do operate carriers, the US is the only one that maintains significant numbers.

One of the obvious implications of Star Wars tech was that anyone with the technology to launch and precisely control orbital payloads - the Air Force, for example - could take out any aircraft carrier in the world, any time it liked.

And the Navy just demonstrated (for the first time) that they could actually protect a carrier battle fleet with a deployed asset, rather than a theoretical capability.

Now while it's never wise to ignore the geopolitics of such capabilities, all politics are local, and there is no more dense locality than the Pentagon. This launch had many messages, and no doubt many intended recipients, but I'd be absolutely stunned if the primary intended recipient of this unspoken message on Navy stationary didn't have an office in the same building, on the same floor, with a parking spot within pissing distance.

SecNav just saw SecAir's smart crowbar and raised him an intelligent tomato can. I'm wondering now what the Air Force has in the hole.
