Exoatmospheric Kill Vechicle Test Successful
angio wrote to us with the
report about the test of an interceptor missle, in the Marshall Islands, was a success. The system shot down a modified Minuteman missle - for more coverage, check out the original article on the Exoatmospheric Kill Vechicle.
there's no indication that the missile killer would be as successful in wartime conditions. The people operating the missile killer knew when and where the missile would be - hardly realisti. I'd like to se this thing tested with only a few minutes' warning. Then we'll see how good it _really_ is.
the only problem i see is if someone shot a nuke, blowing it up here or wherever is not a good idea, unless we could knock it off before it got about 10 miles away!
ive heard about the satellites, ive heard about the ones mounted on 747's, its all good. when will they be able to have the offensive ones...

the russians have a point in this article:
Mutual Assured Destruction has kept the world safe for the past 50 years. with anti-missile technology, one side COULD win. since we have it, i desperately hope no one is stupid enough on our side to destroy the world...
the really useful part of this is the fact that attacks from these smaller states like India, Pakistan, Iran, Iraq could be well detered. this assures that only the big guys: Russia, China, U.S (uk, france, north korea, etc.) could destroy the world. hmmm

This is cool, but what does it really mean for US missile deterrence? One missile took down another, which is a far better kill ratio than we had originally been thinking about, but does it mean we'd now be able to take out a volley of nukes, or would it still be too difficult to take out large numbers? If much of the calculations are done by the rocket itself, that's good, obviously, but is it still too difficult to intercept massive numbers? And wouldn't we be able to see missiles coming at us (we have a rather good radar system, I believe)?

It's great to have a way to protect ourselves, but is this going to cause us to do stupid things, secure in the knowledge that we are invulnerable?

I dont see how a device that deactives a weapon of mass destruction could be called a weapon. Given that it doesnt even have any explosives in it. I think we should mass produce this device and sell it to every country in the world.

I can't believe that this is the only use for this technology. Can this hit planes, too? Why not? And if not, why can't missles just get similar technology as planes (chaff, evasive maneuvers (sp?), etc) to avoid them?
I gotta say this is pretty cool technology, but I'm not sure that it is really going to be that effective. Remember it only takes one nuclear weapon to ruin your whole day, so if 30 are coming your way, they better be pretty effective.
-- Moondog
Since so few people read the original article, note also that North Korea has missle technology that can hit Chicago (as well as the entire West Coast).
Also note that this successful test was against a fairly sophisticated Minuteman II ICBM with several decoys around it. The combined velocity at impact was 15,000 mph, or about 6 or 7 kilometers per second.

System is halted
If I wanted to take out America now, I would first have soldiers infiltrate the US mainland and take out as many US radar installations as possible just about a half minute after launch. The US, thinking that it can simply blast the threat out of the sky, might not immediately launch retaliatory missiles. When their radar is knocked out, it will be too late to launch. Whee.
Finally, the worst thing about the damn interceptor is that we will keep wasting money on worthless military toys instead of something useful like laying new fiber to increase internet bandwidth.

I was at a party yesterday night and the test appeared to be visible in the northern sky right at sunset.
A long fat contrail (do minutemen use H2-02?) streaked through the sky brilliantly illuminated by the then setting sun. After about two minutes or so (I wasn't timing...) the contrail spread as if the second stage had separated and the first state was slowing down. (At least so I though at the time.)
After about another minute or so the contrail stoped and the projectile (missle/mirv/ufo) which was very slightly visible winked out of the twilight sky.
Sidenote: At first I thought it was a plane, but I have never seen a plane contrail that large. Then when the contrail fattened out, it looked as if the missle/projectile had turned and was aimed at me/party.
Request: If anyone happened to take any good pictures of that, it might be interesting to see them. I didn't have a camera with me so I can only post my observations...(sorry)

I was surprised to see so many posts about how we should not proceed with missile defense, because then we will do stupid things because we will feel invulnerable.
This makes no sense. I'll just make a few brief arguments:
1) Mutually assured destruction is a doctrine that only applies in a situation where
(sub-point a) there are a small number of superpowers with nuclear weapons
and (sub-point b) the two superpowers are rational enough not to want MAD
Now, this no longer applies. There are too many "superpowers" (if you insist on counting places like Russia). Worse, there are superpowers that are simply not rational. Take China for instance. Mao was once quoted as saying that he was not afraid of nuclear war. Why? Because China had so many people, nuclear war would only destroy the capitalist superstructure and ensure the victory of the proletariat. Not good.
2) The real threat is not from other "superpowers" but from rogue states and terrorists.
Think about it. Some fundamentalist jihad warrior out there decides that he wants to destroy NYC. Sure, we could threaten to retaliate against his home country or something like that, but in many cases terrorists are increasingly alienated from their westernizing homes. So, this nut case wants to take down NYC, and we are basically powerless to stop him. Think about what the destruction of NYC would mean to the US. Now, since there is simply no way to deterr this kind of behaviour, wouldn't you like at least some way to defend ourselves?
Last point, 3) you don't leave your house unlocked just because you have an alarm system. Further (call it 3a if you want), you don't go around antagonizing gang members just because you have police in your community.
Can your IM do this?
Cnn.com also has covered this story. Nice picture of a vapour cloud! If that had been a nuke, wouldn't that include weapons-grade uranium, plutonium and whatever they use for h-bombs (deuterium and tritium perhaps?). These are highly toxic... would they burn in the atmosphere? I don't think I want to find out.
Obviously this test was canned, with the Pentagon even preparing for failure. It had one decoy balloon - what about all the other types of defenses, including simple chaff? Defense mechanisms are easy and cheap, and will quickly proliferate to cancel the effectiveness of this weapon.
Need we remember Patriot missiles? These things cost an incredible amount of money to develop, and have yet to be proven. No, they did not shoot down any Scud missiles in 1991. Those missiles broke up anyway - Isreal was saved more by the incompetents of Iraq.
Each Exoatmospheric Kill Vehicle costs $120 million. Factor in development costs. Factor in how successful it will be. Factor in how quickly it will be out of date (as defensive mechanisms are developed to counter it). I recommend taking the money and spending it on diplomacy and education to counter such threats. Stop the missiles evening being deployed!
Ok, so they can't launch missiles. So what? That option isn't garruanteed anyway: a state like N. Korea can't produce reliable enough missiles.
Other solution... smuggle a nuclear/chemical/biological weapons in to the US in suitcases and hand pick the target. Better still, bribe people and build weapons in the US - that wouldn't be anymore difficult. More reliable, cheaper and easy to carry out than a missile strike.
It carries a computer that enables it to determine its location by the position of certain stars and then select the target and attack it.
Please correct me if I'm wrong, but this sounds very hard to do. Astronavigation requires at least two astronomical bodies (OK, they've got that), reasonably accurate timing (that's easy) and a horizon.
I just think that determining the location of the horizon from this vehicle would be very hard to do. Oh, you've got to know your altitude pretty accurately, too.
I'm not saying they didn't target it using astronav. It's just that GPS would be far easier, cheaper, and more accurate.
What's more likely is that it has star charts on board and looks for 'stars' that shouldn't be there. Then it attacks them. That could be a neat strategy.
It's going to have to be a lor more accurate than Patriot if it's going to be any use, anyway. Cool toy though.
As far as cold war nuclear theories such as NUT (nuclear utilization theory) and MAD (mutually assured destruction), they are no longer operable in today's climate of nuclear capable Rogue nations (e.g. Iran and North Korea). Hard to use reason with fundamentalist regimes...
From an economic standpoint a useful byproduct of a working national missile defense system would be the alleviation of our need to pay extortion to new and old nuclear powers. Specifically, the billions of dollars we send to Russia each year, and nuclear reactors & food to North Korea... Extorting money from the U.S. has become quite a cottage industry these days, all it takes is a breeder reactor and cheap North Korean Nodong missile parts.

This is exactly why this technology should not be implemented by any nation!! It just ups the ante and drives countries to develop even more lethal, disgusting, deadly weaponry. Why use puny nuclear weapons when a biological weapon will do 10x the damage? Of course, this is great news for the defense industry, who, ironically, is the biggest backer of this project.
We need to return democracy to the US and get rid of the corrupt fat cats!
the article says that it is only good for intercepting one incoming rocket, and that is only used normally by rogue governments or terrorists. Yeah, the terrorists often do more damage than forgeign governments, but *I* am more scared of say China launching multiple rockets at us and us not being able to block em.
not a counter-argument.
After all, we might get hit by a huge tidal wave generated by godzilla playing in the ocean.
While it is true that it may be easier to smuggle chemical weapons into the US than to launch a missile, that is no excuse for having no defense against a missile attack.
Can your IM do this?
But this particular article really caught my eye. Why? Because anything with the name Exoatmospheric Kill Vechicle must kick ass!
Taking out an ICBM under controlled circumstances, doesn't mean that we're unconditionally safe by any means.
In order to get around such a system more sophisticated decoys could be used.
Can an anti-missile missile be defeated by an anti-anti-missile missle? This doesn't impress me. What will impress me is rail gun technology. Ground mounted or in space rail guns are the ticket.

I remember hearing about plans of such intercept missiles in the 80's. So they finally did it.
However the problems are still the same. The launched rocket needs only a few minutes to its target (from Russia that would be 8 minutes I think), so the launch has to be detected early enough. The anti-missile also takes its time to reach the incoming rocket. And for each incoming nuke you need an anti-missile.
The real problems are multi warhead missiles which launch into space and then release up to 10 nukes with individual targets. You would have to hit the missile before it releases its nukes otherwise you would have to destroy ten targets, and as said above it may be hard to reach the missile before it separates its nukes.
So this is not very feasible against big nuclear weapon powers like Russia, it only might prove effective against attacks from the smaller nations which only have few, single warhead missiles.
It makes me want to cry when I read about a government spending such an astronomical amount of money on what is only a one-time tryout of a military toy of dubious need. And if the government does go ahead and build an entire defense system based on this technology, how many orders of magnitude will be the total cost?
All this in a country where hundreds of thousands of homeless people are living in the street and more than 20% of children are growing up in poverty. What benefit is this spending to them? The extremely low probability that some unknown enemy nation may launch a suicidal (and it would be since they clearly realize that the US would of course likely retaliate in kind) nuclear attack means little when you may not even survive the coming winter due to lack of food and shelter.
The cost / benefit ratio of this project is all out of whack. The people of the US do not need this technology to be protected from foreign missles.
The real benefit of such a system is not purely defensive, but stategic, since it would allow the US to launch a first strike nuclear attack against another nuclear country and not have to worry about retaliation from the target country. As a nation, is this the kind of benefit that Americans find it worthwile to spend their tax dollars on? And ultimately, what value is this kind of international power when the country may ultimately succumb to its own internal deterioration?
Ideology is for ideots.
Just a simple question, why? The United Nations is a powerless political body. They can pass 'resolutions' and anything else they want. But they can't enforce anything. The members of the UN enforce these 'resolutions' and 'policies'. The US being the major member of the UN (military wise) dose the brunt of the enforcing.
Not to mention, giving this to the UN would give it to China, Russia, and several other countries that you really don't want to have the technology!
Why would you want to do that?!

If you disperse U or Pu over a city, people just put on dust masks and walk around with brooms, sweeping it up. The stuff's not water-soluble (well, _everything_ is slightly water-soluble, but it's less so than _sand_).
The radiation from Pu is in the form of Alpha particles, which have a range of a couple _inches_ in air. The stuff can't even get through your outer dead skin cells to hurt you.
Beta particles can be stopped by heavy clothing or a sheet of tin foil.
Gamma radiation's the hard one to stop, but nuclear materials in bombs aren't strong gamma emitters, anyways (until they explode, of course, but that's not the scenario here). Gamma radiation is also the _least_ damaging type.
Folks, everything around you is radioactive to a greater or lesser extent; you're getting dosed right now from the chair you're sitting in; we won't even mention the rads you're picking up from space. Eat to many bananas, and you'll flunk a whole-body radiation dose test given to nuke plant workers, because of the radioactive Potassium-40 they contain.
And no, it's not because of nuclear tests or reactors, either.
Radiation is not some horrid bugaboo that will make you simultaneously burn, mutate, and implode if you get a shot of it. It's also not your friend; it _can_ hurt you, so respect it.
The same goes for fire, or electricity.

True.
But it is a case of the blind leading the blind. Who is it that is knowledgeable of threat and proposing these anti-missile systems? The military. Not exactly a source of intelligence and innovation. They always use the most direct/obvious approach (sledgehammer to crack a nut?). I would propose that our tax-payers dollars are better and more productively spent on alternative means for stopping missiles, such as diplomacy.
Why would anybody want to launch a nuclear attack against the US, who could in turn obliterate them? Spending money on investigating and solving this issue would seem wiser to me.
I can just imagine the song "I'm Afraid of Americans" recharting all over the world in the next few days.

If a tree falls on an anonymous coward yelling 'first post' in the forest, does anybody hear?
Who? Somebody who didn't care. Given that suicide bombers exist, obviously there are those that don't. The big question is how they get ahold of an ICBM.
Either a rail car or a missile boat would do; both are mobile, and the rail cars *might* be vulnerable to ambush.
Only the dead have seen the end of war.
All of the Anti-Missile projects I have seen actually are designed to hit the target extremely high in the atmosphere, over the ocean, or over the launching country. Part of the theory is that a country won't launch a nuke if we can shoot it down over their country and drop their own radiation back at them.

> With the Clinton Administration giving away our nuclear secrets wholesale, this is a bit of badly needed good news.
Yeah buddy, the Clinton Administration giving away nuclear secrets with the aid of their amazing Tom Swift time machine. You know, the one that allowed Clinton, elected in 1992, to give away the secret of the W-88 ICBM warhead in 1985.
No, if you bother to read the fine print in the newspaper articles, rather than the cartoons on the editorial pages, you'd be aware that the secret was out the door and down the road years before that loser Clinton ever set foot in the White House. It's a well-documented fact that the nuclear-secret leaks took place during the Reagan and Bush Administrations.
While we're mentioning China and the Bush Administration, maybe you recall President Bush's weak, gutless acquiescence to the Tiananmen Square massacre? Democracy be damned, there are big multinational corporations, big campaign contributors, who stood to face a loss if he had cut off their access to all those cheap and industrious one-dollar-a-day Chinese laborers!

Its completely naive to think this anti-missile system buys you any defense. An incredible waste of billions. THe US will reap what it sows.
This is probably off-topic, but:
secure in the knowledge that we are invulnerable?
We may think that we're invulnerable, but we're not. We're no more invulnerable than the next country. We have no real way of knowing what another country is doing, so long as they can keep a secret. I'm willing to think, therefore, that there are a lot of countries out there not half as loud-mouth and braggy as the United States, and thus I would think we have more to worry about than the rest of the free world.
However, in the lesser grand schema of U.S. political theories, I think this is a good thing, and I'm glad they can feel secure in their successful test. I, OTOH, think that this test doesn't say much. As I've heard it mentioned, and as I thought myself, they planned this thing, unarmed the missile, and knew where everything was supposed to go. Does real war play out like this? I'd like to think not. Nice job guys, but you've got work yet.
Insert mind here.
Deployment of this device would violate the 1972 Anti-Ballistic Missle Treaty. But it's toast, anyway. It was made with the USSR, which no longer exists. And they were violating it when they signed it, and continued to violate it, in spite of our weak wussy Carter-era protests. Finally, the Senate is likely to formally toss it when they get ready to deploy a missle defense.

There is a large qualitative difference between a security failure and an administration that was bought outright by the Chinese. Clinton can be charitably described as our Willy Brandt.
Besides which, if a close examination would reveal that most of the espionage took place under previous administrations, why is Clinton stonewalling to the point that four career FBI agents (that would be four times as many as blew the whistle on Nixon) have testified to the effect that the US Department of Justice obstructed justice in the China spying case? There is every reason to think the U.S. is presently the victim of an espionage project that successfully corrupted an administration at the highest levels.
Ah, but we can count on our fabulous press to bring us the truth and set us free. Maybe not: "Journalistic integrity must prevail in the final analysis. But that doesn't mean that journalistic integrity should be exercised in a way that is unnecessarily offensive to the countries in which you operate..." said Sumner Redstone, new owner of CBS, in Shanghai, on September 28. Gives you a deep feeling of confidence, no?
I wrote parts of this stuff
The U.S. military has, of late, shown consistent kill - to - casualty ratios of more than 1000:1. If allowed to go all-out, that ratio would probably increase.
Yes, China has numbers, and nukes. But they're quite overmatched against the U.S. -- which is one reason they're so interested in exporting military technology: the U.S. can be kept busy better this way than China could manage alone.
Really, though, it's a much better idea to not get into a military situation with them in the first place. We could do without another Cold War. And if it came down to it, they COULD inflict considerable damage to us, even though we'd "win".

1. What good does an anti-missile system do if the most likely way for a terrorist to deliver a bomb is a boat? Missiles are expensive and unreliable, and hard to test without alerting the satelites. Boats are cheap, extremely reliable, and are let into harbors with a minimum of inspection.
2. A working anti-missile defense system is an offensive weapon. I.e. that which is used as a way to defeat an enemy. Without giving out this technology to everyone, whoever has it is instantly a target for foreign governments because they know that they will lose a full-scale nucelar war. It's actually worse than that. Since we're developing this technology out in the open, the foreign governments know that they only have a few years until we cannot be beaten (if the system works). They therefore can assume that we intend to use the system as part of a first strike and preemptively retaliate.
So, let's assume that the USA is not suicidal. The only thing we can do at this stage is declare that we are going to protect the entire world from anyone shooting balisitc missiles at anyone else. Any other course of action will result in some foreign paranoid government nuking us first while they still have a chance to hit us.
A while back someone was talking about developing a stealth cruise missile. The idea was hopefully scrapped. The last thing we need in a paranoid world is for any random explosion to be blamed on the USA because of our unique ability to blow things up without being able to trace who did it. Anytime anything blew up, we'd get blamed.
This anti-missile system is exactly the same thing, a way for the whole world to justifiably get mad at the USA. I wish our president wasn't chasing skirts and would pull his head out of his arse. Maybe he would see the suicidal futility of such a project.
Back in the 50's general LeMay (sp?) was advocating a nuclear first strike against the USSR (haven't typed that in a while..) because of the results of the single game prisoner's dilemma research. Basically, if you expect to play only once, you should cheat. We expect to keep playing the politics game for a long time, over and over. We therefore have to mutually cooperate, that is the best possible solution. Building an anti-missile system is cheating. Saying that you are going to build such a system should prompt the other nations to cheat first.

I saw it too. I live about 50miles east of LA, near San Bernardino. I just got out of the movie theatre (saw American Beauty - excellent), and saw the people near us pointing in the sky. I actually saw the rocket going up. I'd never seen an actual launch before, but have seen the contrails left over.

The big wispy luminescent cloud at the top was probably where the missile reached true space, about 50 miles up. The exhaust gases will behave differently there versus lower down in the atmosphere, so much so that they were actually diffracting the sunlight, giving it that rainbow effect. To see what it looked like, check out this article on CNN:
http://www.cnn.com/US/9910/02/missile.defense.tes
I have to say the contrail was one of the most amazing things I've ever scene in the sky, seconded only by good aurora borealis shows. (I'm from Canada, so have seen quite a few). Got me to thinking about how ironic it would be if there ever were a full-scale ICBM launch. Quite a specatacular sight to see tens or hundreds of these contrails going up. At least it would be until your eyes were burned out by the flash of the first retaliatory burst...

Not true. Until this past May, it was believed by professional rocket scientists that a rocket has too much acceleration to re-acquire GPS satellites while in flight. At least that's what they were saying in public.
It was amateur rocket experimenters (from JP Aerospace of Sacramento, California) who proved that GPS in-flight re-acquisition could be done, during a high-altitude test launch at the Black Rock Desert in northern Nevada on May 23, 1999. They were attempting to get the first amateur rocket to an altitude considered space, 50 miles or 264,000 feet. Though that wasn't achieved, they did make these accomplishments:
I was there to help with the launch and recovery operation. I'm not officially a member of the JPA organization but was there representing another amateur rocketry organization. We usually encourage each other to push the envelope.
See also CNN's coverage of the JPA launch, though they didn't mention the GPS accomplishment because it's probably too obscure a fact for their audience.
I was driving up to the local coffee shop when I saw it. I have to say, it was an oddly beautiful site as the trail blossomed and then faded, and as the sun light refracted through the smoke to create a range of colors.
Of course, I had no idea what it was -- we thought it was just another rocket blowing up due probably to some metric to english conversion error...

I have been wondering why the ABM approach these days is to ram the incoming target with an interceptor, destroying that target by the high kinetic energy of a multiple km/sec collision.
It would seem that this would make aiming harder than the older method used by the Patriot and other anti-aircraft/anti-missile systems. Those systems use an explosive, detonated at closest approach, to throw a spray of high velocity projectiles at the incoming target. This "shotgun" approach would seem to me to have a higher kill probability. In the past, we had thousands of nuclear armed interceptors, so the same issue applies to that technology. For example, fleet defense doctrine against massed aircraft attack was to use nuclear missiles to destroy the aircraft... and almost every US combatant, in the past, carried these missiles!
So, does anyone know why they now use kinetic kill with a single maneuverable projectile?
The only good weather is bad weather.

If we can afford to lay that out for a test firing, I guess it puts that NASA Mars orbiter loss into perspective.
by Mike Buddha -- Someday the mountain might get him, but the law never will.
Ok, so if they shoot a slug at a reentry vehicle containing a warhead and atomize it in space, has there been any discussion about using this device to ward off a stray comet, meteor, or asteroid that could cause significant damage to the Earth?
:)
It seems that this system may serve a dual purpose, at least over North America.
That is if the spacebound oil drillers don't blow up the asteroid first.
1) When a missile is launched, the errors in the initialization of the inertial navigation system are quantifiable in a statistical sense.
2) The onboard computer can propagate the error covariance of the navigation states to the point in space where the star fixes are taken.
3) At this point, an error between the expected line of sight to a star (each measurement is composed of two angles perpendicular to the centerline of the sensor taking the measurement) has strong statistical correlation to the attitude errors.
4) The attitude errors at that time can be VERY strongly correlated to position error. The azimuth error (error in the estimate of which way north is) is commonly one of the larger contributions to position error.
5) In this way, measurement of the attitude errors of a missile can effectively be converted into correction of the navigation estimate of position.
6) As an aside, there is a reason you care which way north is. The reason is this: missiles normally use measureable characteristics of the earth to initialize their navigation. Measured gravity tells it which way down is. Earth rotation tells it which way north is. In a relative sense, accelerometers (in a given price range) are more accurate in locating the direction of down than gyroscopes are at locating north (the axis of earth rotation). It's irrelevant what frame of reference you choose to navigate in; you are still stuck with your initialization errors about north and down. Given two non parallel directions, you can build a 3-axis coordinate system using vector cross products and orthonormalization techniques.
Hope this helps. I have been working on these sorts of systems for about 16 years now, so I have a good idea how things are done.
Unfortunately, yes you're wrong. US allies on the Pacific Rim would gain zero benefit from an "Exoatmospheric Kill Vehicle". Well, maybe epsilon benefit.
At close range (under a hundred miles) ballistic missiles are unnessary. China or North Korea could easily use more standard missiles (including ship/aircraft based) or even large artillery shells. Star Wars defenses won't help against that.
If any of you guys are interested, this is a pretty cool picture I scanned in from the Santa Maria Times of the minuteman rocket that was the target.

If you are old enough to remember the Desert Shield, Patriot missiles should ring the bell.
...
If not, let me remind you. There was much ado
about those missiles, and how they destroy the
Iraque's Scuds. After the war, however, we've
finally were able to read the true story: there
was not a single instance where Patrior missile
actually homed on Scud and killed it. It was mostly a propaganda, pure and simple.
There were several instances of fake or 'well controlled' tests with other anti-missile missiles.
I am for strong defense, and that's why I'm concerned with sometime too cozy relationships between the military and companies like Ratheon et al. This is what is called a 'military-industrial complex'. Lots of moneys are getting wasted, thanks to this complex. I hope this won't undermined our defense capabilities too much. Oh well
Grunt. Oink, oink.
It went up about 10 minutes after sunset, so the flare of the engine was easily visible as it cleared the hills, and as it climbed, the smoke trail went from a dark purple to orange, to yellow to white. As the rocket gained altitude, there were some very beautiful shimmering effects against the deep blue sky, and when it was way up there, the ice crystals in the upper atmosphere made a scintillating ring, with radiating white lines. Again, I've got several size 11 footprints in my ass for forgetting to bring the camcorder.
Ironic that this goes down as one of the most incredibly beautiful sights I've ever seen in my life - and not only was it not natural, it was probably one of the most evil devices ever constructed by mankind.
I hope that I never someday see dozens of these things climbing from the low hills into the sky, headed towards the Evil Despot (TM) of the day. I may have to gouge my eyes out after witnessing that beauty.
