Good work, team USA. Another decade or two of testing and refinement, then a decade or two of production and we'll finally be able to fend off a ballistic missile attack from the USSR.

In the meantime, can it do anything practical, like stop people from flying planes into buildings or setting off car bombs? Because that would be a lot more helpful these days.

Did the DoD cheat on this test? In a lot of prior tests they cheated by telling the anti-missile system the launch location, launch time, trajectory, etc ahead of time. I believe in some cases they even had the missile actively broadcasting a signal to make it easier to target.

I'll be impressed when everything about the launch: the source, the timing, the location, the trajectory, the type of missile, etc is unknown to the anti-missile system.

Of course I'll only be impressed by the technical achievement. I'll be extremely depressed by the massive waste of money and effort.

The airborne laser is a theater defense weapon against ballistic missiles (think: Saddam Hussein firing SCUDs during the First Gulf War), not a ballistic defense weapon intended to protect the United States against a mass launch of nuclear weapons, an exercise which many people believe is impossible. (If you have a 97% success rate and only 3% of the warheads make it by, that is still failure.)

Of course, what is a theater defense weapon for the USA may be a national defense system for a small country like say, Taiwan.

$2 billion dollar US Laser Plane? Meet the mirror.

Yeah, I had this idea when I was like six. I asked my brother, my brother asked Edward Teller who said that mirrors are an imperfect defense against lasers because they are not 100% efficient -- they start to degrade as they are exposed to lasers and eventually they fail and you can zap the missile underneath.

Oh, Dr. Teller is quite correct that mirrors don't reflect all the light. However, suppose you coated the rocket with reflective material that reflects a modest 95% of the laser light. That means you'd have to hold the laser on the target for 20 times longer than normal in order to detonate it! I doubt the missile stays in range that long. Now suppose the missile rotates a bit. Now you have to hold it in place for something like 100 times as long. It's a totally infeasible method of anti-ballistic missile defense. It's the equivalent of saying "please stand very still while I drop this piano on you". It'll work great in a test, but when faced with an enemy of any technical sophistication, is virtually guaranteed to fail miserably. Oh, and as for "zapping it from underneath", I think that would be unlikely to work during the ascent phase, which is the only chance this boneheaded military boondoggle has a chance to be effective, because the underside of the rocket would most likely be shrouded in an optically opaque incandescent plasma; the rocket exhaust.

Not to mention, all of America's "enemies" right now are only armed with the weapons we sold them 20 years ago, and that usually doesn't include stuff bigger than a Stinger missile.

God I would love to be in the same room as the DoD budget with a pair of scissors.

I'm no rocket scientist but I thought ballistic missile meant a missile that took a sub-orbital path to get to its destination. That means it touches space but doesn't make a full orbit. To my mind that means that a ballistic missile is by definition not a local theater weapon and SCUD missiles don't qualify as ballistic. Am I mistaken in my impression of what these things mean?

I once read this described as shooting a bullet out of the air with another bullet.

I'm going to try to figure out how to not be around them or how to get them away from the bad guys in the first place.

I'd see this as a waste of dollars, but then some weird scientific discoveries are made whenever we pump dollars into this sort of thing. Even if we find no practical applications for this tech, I am sure there will be some side technologies that Boeing will patent and make a mint from!

Oh, that was 'zap the missile underneath the reflective coating', not 'zap the missile from underneath'. Sorry for the confusion. As above, I think it'd be very difficult, if not impossible to defend against a mass ballistic missile launch, not just because of mirrors, but because it's really much cheaper to dump out a couple hundred more missiles than it is to make verrry sophisticated things to kill those missiles.

I'm also not sure where the idea that ballistic missiles have to be very long-ranged (which is what Babblesort seems to be implying) comes from -- the V-2 is commonly considered the first ballistic missile.

Wikipedia, but:

Tactical Ballistic Missile
Theatre Ballistic Missile
Scud is a series of tactical ballistic missiles developed by the Soviet Union during the Cold War and exported widely to other countries
Theater missile defense: Targets medium-range Theatre ballistic missile, which travel at about 3 km/s (6,700 mph) or less. In this context the term "theater" means the entire localized region for military operations, typically a radius of several hundred kilometers. Defense range of theater defensive systems is usually on this order. Examples of deployed or soon-to-be deployed theater missile defenses: THAAD, Airborne laser and Russian S-400 Triumf.

Used to work at the company that made the steering mirrors. Everything was either transparent, or covered in 24k gold (which is highly reflective in the desired bandwidth). The steering mechanism is perhaps the most beautiful technical device I've ever seen.

from http://yarchive.net/mil/laser_weapons.html

"Reflective coatings are a: imperfect and b: *fragile*. The reflectivity is entirely a function of a micron-thick layer at the reflecting surface; it doesn't take much energy to turn it into something else. And what you get when you burn, melt, ablate, or shatter a reflective surface, isn't likely to be very reflective on its own.

The difficulty in ensuring that the laser's own necessary internal mirrors can stand up to the beam, is one major limiting factor in laser weapon development. And the laser designer has all the advantages here; he only needs to mirror a few specific surfaces, those surfaces can be in the protected interior of the vehicle, and he can devote massive cooling systems to those specific surfaces. The relective-armor designer has none of these working in his favor, and so his armor will not survive as intense a beam as the laser designer's mirror can deliver."

I'm curious about the effect that this type of missile defense would have on nuclear deterrence--if you have a missile defense system that works, you're more or less removing the deterrent threat that simply having nuclear missiles poses, right? Aren't you messing with the whole equilibrium now? Wouldn't our "nuclear enemies" actually need to fire the missiles rather than just have them now? I'm confused.

A high powered laser like this one would just melt most mirrors. It would take something quite exotic to handle the energy without up and melting.

That's not to say it's not fighting the last war, but honestly it makes far more sense than putting a laser on a satellite. This could be very useful for theater missile defense if we were forced into a war with Iran or North Korea, for example.

Why would this anti-missile system be necessary?

In the 1991 Persian Gulf War, Saddam fired missiles at his neighbors and Israel, in an attempt to terrorize the populations and draw Israel into the war. Some of these missiles were rumored to be carrying chemical weapons. If the Israelis had jumped into the fight, it was widely thought that it would shatter the alliance built by the U.S. and Britain.

Thus started the Great Scud Hunt and the media's fascination with Patriot missiles.

Now, imagine that the same thing happens with another nation. Say, North Korea. They start to rattle sabers with the threat of lobbing missiles at Japan, some of which could be rumored to contain chemical or nuclear weapons.

You could nuke North Korea, sure. But do you want to be lobbing nukes so close to China? And South Korea? Seoul is only a few dozen miles from the DMZ.

In theory, an airborne defense gives you more strategic, tactical and diplomatic options than just "Nuke 'em all and let God sort 'em out."

Well,

Since the airborne laser is intended to defend against theater level ballistic missile attacks, it doesn't really have any bearing on say, Soviet-scale Armageddon. Like, a few years ago there was some diplomatic fuss about deploying anti ballistic missiles, and the United States was trying to emphasize that it was going to be like 50 interceptors (and Russia was still against it). I thought (and this is pure conjecture) that emphasizing this was basically saying "Look, Russia, this isn't about you, this is about North Korea or Iran possibly doing something. You can still MAD us."

stbalbach : I wonder though, why not ground-mounted surface to air lasers?

There are a bunch of reasons actually; a ground based is going to be far more limited in it's ability to "see" the target early, giving it less time to engage, and more importantly, because the ground might offer limited strategic locations for batteries, it might be possible to map them and launch missiles in their blind spots. Also, they are, as always, subject to airstrikes and other forms of nastiness that any ground based weapon has to worry about.

Once you put something in the air, while vastly more fragile, it becomes much, much harder to plan for.

I hate how much money crap like this costs, but I like the idea that as a weapon, it has pretty limited uses. Assuming it could be perfected (big, giant "if" here) it is really primarily useful in defense. As an offensive weapon, it would actually kind of suck. And I'm ok with the world spending more time figuring out how to protect itself rather than how to attack others.

Still, this whole thing reminds me of the immortal words of Socrates who said, "I drank what?"

What I'm saying is that using the conventional wisdom on nuclear weapons, developing a missile defense system almost looks like provocation to me and significantly ups the proverbial ante. With the stakes involved, you'd better hope the system works 100% of the time.

Again, it's by no means foolproof, but that no one's attempted a first nuclear strike since the US bombed Japan in WWII must lend some credibility to deterrence as a defense tactic. And it's no less crazy than thinking anyone's going to completely disarm.

But then the non-diplomatic options you're left with (and you have to have some in order to even be in the sovereign-nation game at all) are along the lines of pre-emptive strikes or massive retaliation. Neither of which is great, and neither are they foolproof, just like missile defense isn't foolproof. And at the end of the day, they're actually just as expensive, either in terms of lives, dollars or both.

I would guess that among MeFites, I'm old enough to recall honestly being concerned about a selective service draft for the 1991 war, because of some predicted casualty figures.

Terminal phase interception is much harder than boost phase interception, as the missile is traveling much faster, and even if you manage to break it up, it's still going to come down on the target area unless you manage to get a perfect kill that sets off the warhead.

There's pretty good evidence that Patriot got close enough to break up several Scuds, although they were a massive failure at actually stopping the Scuds because they weren't accurate enough to detonate the warhead prematurely.

Details aside, the point is that the project at hand has a much easier time doing what it's supposed to do. The hard part was getting a big enough laser to fit on a plane.

The aircraft has to be in the air prior to the missile launch, so it's not particularly useful as a defense against an attack out of the blue unless you go all 1960s SAC and keep some in the air around North Korea and Iran at all times.

I think it's more targeted at situations like the 1991 Gulf War where you know tensions are high and missiles may well be launched. It's like Patriot, only airborne and more likely to work. Terminal phase intercept is very hard. Boost phase not so much. You poke a hole in the fuel tank and the missile will likely veer off course and blow itself to smithereens. Plus the missile is traveling significantly more slowly.
