Anti-Missile Technology To Be Tested on Commercial Jets
Hugh Pickens writes "As many as three American Airlines passenger jets will be outfitted this spring with laser technology intended to protect planes from missile attacks. The tests, which could involve more than 1,000 flights, will determine how the technology holds up under the rigors of flight. The technology is intended to stop attacks by detecting heat from missiles, then responding in a fraction of a second by firing laser beams to jam the missiles' guidance systems. A Rand study in 2005 estimated it would cost about $11 billion to protect every US airliner from shoulder-fired missiles. Over 20 years, the cost to develop, procure and operate anti-missile systems could hit $40 billion."
A german police chief was asked on TV the day of the London bombings what extra measures should be taken. He said: "None. The measures are effective as they can be; we cannot avoid all terrorist attacks just as we cannot avoid all crime." I was impressed, He was a really intelligent man. A shame nobody bothered to inform the manufacturers and proponents of this system about this particular wisdom.
Number of passenger planes shot down by heat seeking missiles: 0
Number of passenger planes used as missiles: 3
So, err, don't you want the ability to shoot down passenger planes? Or is the next step to install "special" missiles on buildings that might have passenger planes flown into them in the future which can bypass the anti-missile system? And if that's the plan, what's to stop them bad guys (who are under every bed) from using those missiles to shoot down the planes?
How we know is more important than what we know.
no. AA missiles have a perfectly fine time manoeuvering. Something about not having to worry about a 9G turn limit. Not only that, commercial airplanes aren't exactly manoeuverable to begin with. They don't have to be, it's nearly impossible to make them so, so they aren't. Intercepting will be no problem. Especially if they use a radar guided missile. The point of putting in the IR spoofing mechanism is to protect planes from manportable systems (which are pretty much all IR guided) during take off/landing (because manportable systems cannot reach up to cruising height, and presumably any larger threats would be picked up because they're BIG and hard to smuggle).
Since the airplane laser is there to "jam" the missiles' optical/IR tracking instead of destroying them, it should certainly be possible to redesign the missiles' guidance system to use the airplane's anti-missile jamming laser as a homing beacon, turning the defense mechanism into a practical bull's eye target.
Since laser light is directional, a simple pin-hole shadow mask in front of a CCD would be enough to compute a satisfactory approach vector to keep the target within re-capture range.
Like many DHS and other agencies' schemes, they may initially look good on paper (particularly to the uninformed public) but are likely to be proven worthless money sinkholes practice since they rely on the premise that terrorists will be unable to adapt... much like the MPAA was banking on AACS, HDCP and BD+ never being broken. At best, I think this is a $40B money scheme to make the promoters' friends richer.
Not a single passenger jet has been downed from the type of missiles these "high power lasers" are supposed to be able to prevent. Not a single one.
Only through dumb luck.
Example 1.
Example 2. (Be sure to scroll down and read about the Israeli 757 that was fired upon in Kenya.)
Example 3. (Ok, not a passenger plane, but the terrorists apparently thought it was... and it is a common airliner.)
It's only a matter of time, and everybody knows it.
You know what the FAA does when it has a situation that it knows will eventually result in a disaster costing hundreds of lives? They try to fix it. That's part of their job.
Friends like the United States. Remember that it was the United States that gave the Taliban the high teck wepons used against the Soviets in Afganistan.
Undetectable Steganography? Yep, there's an app fo
Well the pilots survived that crash landing... so that's something?
Actually this crash landing was pretty exceptional in that 50 people survived the 200mph crash landing. Many of those that died died after the crash from drowning[1], as they prematurely inflated their life jackets which made it impossible to get out of the plane as soon as the water level had risen above the level of the doors.
Your chances aren't great, since the year 2000, of 652 people involved in commercial jet emergency water landings, only 10 have survived[2].
I'd probably prefer to be blown up by a missile, but I couldn't say for sure until I've tried both.

I work for the company that builds it. I'll even go so far as to say that I had a hand in the design of several key systems and leave it at that. Point 1: The system proposed here is a variant of a system that is mounted on many military aircraft. It uses a laser to inject false tracking information into IR guided missiles. These missiles do not, for the most part, use focal plane arrays or any other similar technology. They have one pixel, and they use spatial modulation to generate corrective track and guidance information. The jamming laser cannot blind other pilots, shoot down other aircraft, or be used by the missile to generate valid track information (a concept we call home on jam). These systems are tested through many progressive levels using pieces of and then finally entire shoulder fired missile systems - real missiles, right out of the tube, with mass equivalents inserted in place of the warhead package. We shot real missiles at these systems dozens of times, and they work really, really well. Point 2: The shoulder fired threat is real. There have been attempts to smuggle missiles into this country, as well as shoot down commercial aircraft (in Kenya, not in the US). They are cheap, readily available on the black market, and any yahoo with five minutes training can use one. Point 3: Given both of the above, and with my paycheck riding on it, I still think it's a poor use of money. If you want to dollar cost average lives, I think there are other targets which have a greater possiblity for loss of life that can be protected for less money. What about using a SAR to try and keep pipe bombs out of malls or schools? What about a tracking system to keep an eye on LNG tanker trucks, a big mobile explodely temptation to terrorists if I ever saw one. 9-11 involved aircraft, but beyond that I think we're fixating a little too much.
Jealously hoarding mod points since 2007.
