Hamas' attack on Israel: why Iron Dome lets rockets through

This is reported by Defense Express. 

The first hours of Hamas' huge attack on Israel allow us to draw the first conclusions from the battlefield, which for years was thought to be incredibly specific and predicated on the IDF's absolute superiority over all imaginable opponents, particularly terrorists from Gaza.

Overloaded Iron Dome

Despite Israel's sophisticated missile defense system and the Iron Dome, a missile interceptor specialized in intercepting rockets with an 80-90% proven efficiency, Hamas was able to launch rocket attacks on cities and critical infrastructure, such as the Rutenberg power plant, which accounts for 20% of the country's generation.

The causes for this are numerous. By concentrating the attack, any anti-aircraft system can be overwhelmed. And that is exactly what Hamas did, claiming to have launched 5000 rockets. At the same time, the IDF's figures of 2200 missiles fired are far from accurate. 

Even if 90% of the 2,200 missiles were intercepted, 220 of them managed to penetrate the missile shield. Simultaneously, with such a big launch, it is not only the systems' ability to intercept part of the targets, but also the presence of the missiles themselves, after which the launchers must be reloaded and become powerless.
