Anti-Missile Technology To Be Tested on Commercial Jets 490

Posted by Zonk from the because-our-airline-tickets-were-too-cheap dept.
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."

        The article says that the system being tested was developed by BAE which is a British company.

        Hard to see how BAE could be very close to an Israeli defense company given that 1) the largest single contract BAE has outside NATO is to supply aircraft to Saudi Arabia and 2) the UK government imposed a partial embargo on sales of military equipment to Israel after Israel broke a previous undertaking not to use UK supplied arms in the occupied territories.

        Why spend $11 billion to stop a threat that is basically non-existent? Those incidents you pointed out happened in insecure areas, and even then they didn't succeed. The threat to American passenger planes in the US (and really 99% of everywhere else) is so small you probably can't even measure it. This is a boondoggle that will do nothing other than take tax money and put it into the hands of defense contractors. That money could be put towards something far more productive than this, and something that could save far more lives.

        Ultimate safety is not possible, and it's not even desirable (IMHO of course). If we spent this much money on protecting every conceivable way for terrorists to attack us, we would go bankrupt. Preventative action is only possible to a certain extent. Take care of the low-hanging fruit, then let the rest of it be handled by law enforcement.

        This strikes me much like many other proposals: There are many other fields that a $40 billion investment would save many more lives. Improving car crash standards a bit, for example.

        It's like banning the .50BMG in California because of it's usefulness to terrorists. Never mind that there haven't been many incidents worldwide of terrorists using it, much less in the USA/Europe. The only case I know of where it was used in a crime caused no fatalities - oh yeah, and it was the guy who built a tank out of his bulldozer. Not exactly a guy concerned with practicality. For the cost of a .50BMG rifle you can get a lot of explosives - which terrorists do have a history of using.

        Yes, I'm performing risk analysis - I'm not saying that terrorists won't manage to shoot down a commercial aircraft with a manpad, but is it worth $40 BILLION to try to stop it? A full plane would average what, 300 people? Even if it saves a plane - that's $133 million per life saved. Makes health care look cheap.

        Right now, going by history - 300 people X zero average incidents per year = 0 average dead per year.

        I mean - this system isn't guaranteed to work, even if they do shoot a IR missile at the plane(and the odds are currently low that they will).

        I think we need to step back and stop concentrating on air travel so much. I mean, the terrorists attack plenty of places other than airlines. That was, relatively speaking, a one time deal. We'd be better off spending the money protecting malls and schools.

        Hmm, despite being modded informative, the parent is quite badly informed in spots:

        - The US warship, the USS Vincennes, which shot down the Iranian Airbus was *NOT* under attack by boats and the aircraft was not on final approach. Crew believed the Airbus was an Iranian F-14 and deliberately shot it down.

        The straits of Hormuz are so narrow, it's impossible to *not* be near the Iranian shore. The same holds true, to a lesser degree, for the entire gulf.

        - "In 1987, Islamic terrorists working with Libya blew up a British Airways 747 over Scotland."

        Several problems with this statement: Firstly, The plane was not "shot down", as per the lead-in to your comment. Secondly, they were not Islamic terrorists - they were believed to be agents of the intelligence service(s) of Libyan (exactly who is unknown, the man convicted for the bombing may well end-up being found to have been wrongfully convicted, and may be released).

        - "In 2000, the Islamic terrorist group, al-Qaida, attempted to blow up between six and twelve commercial airliners flying across the Pacific at the same time. This plot was discovered at the last minute."

        This sounds a bit speculative, and you've provided little information. Can you provide more details and/or references?

        - "A few years after that, Islamic terrorists based in the UK attempted to cause explosions on several airliners by mixing ordinary household liquids into explosive combinations while the plane's were in flight. This plot was foiled by inspectors who noticed several passengers attempting to board the aircraft while carrying unusually large amounts of legal but curious household chemicals."

        This is utter rubbish.

        Those charged had not bought tickets, so there's no way this plot could have been foiled just prior to boarding. Some didn't even have passports. Most of those arrested were not charged. The rest have not yet been tried. Even if those charged were plotting to blow up planes (and there is doubt), there is a shadow, nay a huge pall, over the viability of liquid, binary explosives being used by passengers to blow up aircraft.

Once the public has swallowed the innocuous cover story, they can install much more capable systems on commercial aircraft. Any aircraft with weapons installed by the 'Defense" Department is military by nature, regardless of whether it carries civilian passengers. Those passengers will serve as human shields to cow others from shooting down these planes.

    Any nation that allows US commercial aircraft into their airspace has suddenly agreed to letting the US military overfly their countries. Aircraft can be flown by remote control, including commercial aircraft with weapons. This is an extremely dangerous precedent. If another nation tried this, the US government would refuse them entry.

  • Airliners are HUGE aircraft. Plus, they have redundant engines. Plus, the types of SAM systems we're probably worried about are shoulder launched since terrorists aren't going to be able to acquire or move larger systems. These smaller warheads probably can't take down an airliner under reasonable conditions. That all adds up to a waste of money to me.
  • Perhaps they're competing with Boeing [slashdot.org]....
  • But can they be attached to sharks?
  • Neither of the systems mentioned in subsequent research has ever been fielded in a combat environment.

    Long and short of it: it is unproven.

    Never mind the fact that there has never been an airliner downed by a MANPAD in the US.

    Regardless, consumers will refuse to fund AA in this venture. If AA's costs rise, they will just fly on another airline.

    A perfect opportunity to build a laser-jammer tracking missile.

    Why, as soon as the laser-jammer starts up, instead of tracking the now-lost IR signature, instead switch to a tracking system that uses that nice strong clear laser signal instead!

  • So..they make Antiaircraft laser technology avalilable and cheap so that expensive antiaircraft missiles are rendered obsolete.

    And later on when terrorists build technology based on these lasers thenselves to hit aircraft, they will come out with what? A tachion-laser detector coupled to anti-light lasers in each commercial airplane?
    • One way of attack is still far from bein obsolete: (ab)using the low paid airport workers to manually place the explosive inside the plane while it is still on the ground.

    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.
