A Skeptical View of Israel's Iron Dome Rocket Defense System

Lasrick (2629253) writes It isn't as if real analysis of Israel's "Iron Dome" isn't available, but invariably, whenever Israel has a skirmish the media is filled with glowing reports of how well the system works, and we always find out months later that the numbers were exaggerated. John Mecklin at the Bulletin of the Atomic Scientists looks at the coverage of Iron Dome in the recent exchanges between Israel and Hamas and finds the pattern is repeating itself. However, 'Ted Postol, an MIT-based missile defense expert and frequent Bulletin contributor, provided a dose of context to the Iron Dome coverage in a National Public Radio interview Wednesday. "We can tell, for sure, from video images and even photographs that the Iron Dome system is not working very well at all,"' Includes a good explanation of the differences between Iron Dome (a 'rocket defense system') and missile defense systems pushed by the U.S.

    This post (like the one with the Brazuca for the World Cup) is certainly subject bait. It works because it attracts lots of tangentially on topic comments but that doesn't have anything to do with the subject matter of the article.

    So please, don't fall for it. Don't spend the whole comment section arguing about causes and consequences of the conflict, who started it, who deserves is, etc.

    Stay on topic and discuss the technical aspects of the missile system, at least that is what should be discussed here.

      In the case of SDI the PR might actually be worse than useless (playing mutually-assured-destruction isn't much fun to begin with; but if one or both sides come to believe the hype about a missile defense system things could really go downhill). In the case of 'iron dome', though, it might actually be helpful. Barring fairly substantial increases in rocket construction expertise, or acquisition of something particularly nasty to fill them with, the attacks it is supposed to defeat are only modestly dangerous; but extremely inflammatory.

      Given how lousy the alternatives for appearing to be taking action against the rocket menace are (grovelling through every last hidy-hole in Gaza is militarily doable but a PR debacle and unlikely to turn up more than a few bits and pieces of impoverished machine tools, because low-end rockets just aren't that hard to build. Paying Hezbollah a visit might turn up somewhat more interesting stuff; but that hasn't turned out well in the past) a system that postpones or prevents somebody taking the bait and trying them might be quite helpful.

      No, in the case of Iron Dome, that's only PR too. They're shooting $50k+ missiles at $800 rockets. Even after factoring in that Israel's per-capita GDP is 20 times that of Palestine's, that's still a losing proposition, even *if* they had a 100% hit rate (which this article is suggesting it's anything-but) and assuming that you get the launcher, radar, etc for free instead of the actual $55 million per unit. It's in Palestine's best interests that Israel deploy as many of them as possible and try to shoot down every last rocket, because every shekel they spend on Iron Domes and missiles is a shekel they don't spend on jets, tanks, and bombs.

      B. Not living in Israel is not really an option.
      Obviously, for some, it is. Long term, however, history showed that Jews don't fare well when not under self government. Thankfully, antisemitism suffered a major blow back after the Nazies lost WWII, and so people who grew up in western countries don't think of it as something real. It is illegitimate, and still fairly rare. That is a good thing. Sadly, it is also very far from non-existing. Jews in many western European countries don't wear external religious signs, and if they do, experience daily harassement. What's more, the current trends are not promising.

      Maintaining Israel is a survival need. The fact that Israel's current strength pushes the danger back quite a bit is proof that the need is real, not vice versa.

    You don't expect a critical appraisal from the vendor, do you? Take his, and everyone else's reporting with some degree of skepticism.

    One notable fact that was tangentially mentioned is that one doesn't see any 'hits' in the media. I would think one would be able to see the effect of the missile intercepting the targets at least some of the time. Given the intense media coverage, one wonders. It's certainly possible that by the time the interceptor hits the target it's too small to visual, but there is one hell of a lot of energy involved. Kinetic energy often creates sparkly bits that can be seen.

    It is also hard to argue that this ISN'T just one more aspect of the public relations game that is endemic to this conflict. Both sides (as is pointed out in TFA) engage in trying to get the other side to look mean and nasty. It's way more complicated than that.

If they do fire back, and go as far as to warn the targets, Hamas gathers their children and brings them to the target creating mini-martyr's and generating huge sympathy, especially from the west.

    As a general on the discussion so far, I find it informative that the most vitriolic comments directed against Israel and Jews were posted anonymously; the posters are well aware that their remarks are defamatory and have no appropriate place in civil discourse.

    Per the preceding discussion, the staggeringly different perspectives on life, the afterlife, martydom, etc. add a dimension to the conflict that is not easily resolved. As the product of a "modern", western civilation and education, I personally find it impossible to subscribe to any sort of notion of the promise of heaven, nor do I have any willingness to sacrifice myself for a religious cause. The asymmetric philosophy that enables suicide bombings, among other atrocities, has had an outsized influence on the conflict and global perception thereof.

They might as well just omit the warheads to save money and increase range. Every $50k shot Israel fires with those systems costs 25 Israelis' annual tax contribution to the IDF. Every $55m system they deploy costs 27.500 Israelis' IDF tax contributions.
