Behind the success of Iron Dome

We have all seen and read much lately about the great success the Iron Dome system has proved to be in protecting Israel from HAMAS rocketry.  The folks at the military blog Strategy Page put up an article last week that goes into quite a bit of detail about the system, it’s effectiveness, it’s costs, and the frantic efforts of the Israelis to get more batteries up and running when they first learned of the impending attacks.

An excerpt:

The latest war with Hamas began on July 7th as Hamas ceased even pretending to halt the rocket attacks (by non-Hamas Islamic terrorists) on Israel coming out of Gaza.  Hamas began firing a lot more rockets and the seven Iron Dome batteries in service were the primary defense against a rocket hitting an inhabited area.  One additional battery had already been delivered but was not activated yet.  [The] Israelis wanted more Iron Dome batteries, so the air force and the manufacturers went to work.  Inventory was checked and it was found that there was enough equipment in stock (newly manufactured, used for development work or almost completed) to quickly equip two more batteries.  Because there were already seven batteries active and personnel had been selected, trained, and assembled for the new eighth battery, it was calculated that by prying away a few key people from each of the eight existing batteries, activating reservists with Iron Dome experience, using some contractor personnel (civilians who had worked on Iron Dome even if they had not done so while in the military), and calling in some military personnel with similar skills (maintenance, operations) to those used by Iran Dome crews … [more could be put online].  By speeding up the training and certification of the eighth battery as well as the newly formed two batteries, all could be in action soon (as in a week or less).  The eighth and ninth batteries went online by the 11th and the tenth battery was active by the 15th.  Military and contractor personnel, instructors, and the new crews had to work round the clock for over a week to make it happen.


So far Iron Dome has shot down 85 percent of the rockets it calculated were headed for a populated area. The Tamir missiles used by Iron Dome weigh 90 kg and have a range of 70 kilometers against rockets, mortar shells, and artillery shells up to 155mm.  Iron Dome can also shoot down aircraft and helicopters (up to 10 kilometers/32,000 feet altitude).  Iron Dome is the principal defense against short range rockets fired from Gaza or Lebanon.  Work is underway to increase Iron Dome range from 70 to over 200 kilometers.

Hamas has already (in 2012 and 2014) tried to defeat Iron Dome by firing a lot of long range missiles simultaneously at a few cities.  In theory this could overwhelm one or two Iron Dome batteries.  But Israel is able to keep 24/7 UAV watch on Gaza and spot attempts at large scale simultaneous launchers.  This enables Israel to bomb or shell many of the launch sites.  This results in many rockets [being] destroyed on the ground or launching erratically, and [then] landing within Gaza or nowhere near where they were aimed.  Because Iron Dome can track hundreds of incoming missiles, quickly plot their trajectory and likely landing spot, and ignore the majority that will not land near people, Hamas needs to put hundreds of larger (long range) missiles into the air at the same time to be sure of causing lots of Israeli casualties.  So far Hamas has … been unable to get enough rockets into the air at the same time to make this work.
