A month into the U.S. military campaign against Iran, Israel’s vaunted air defense system is showing its limits. Just in the past 10 days, major cities including Tel Aviv, Dimona, and Arad sustained significant damage when Iranian missiles successfully evaded Israel’s network of interceptors.
The most obvious explanation for the apparent failures is that depletion of Israel’s interceptor stockpiles is forcing the Israel Defense Forces to ration munitions or prioritize targets. But the faults in Israel’s air defenses almost certainly have deeper roots. After all, even if forced to defend only the most important locations, Israel would almost certainly place Dimona — a city located near several of Israel’s key nuclear facilities — at the top of the list.
The more worrisome reality is that gaps in Israel’s air defenses may be detection (rather than interception) failures resulting from damage to the radars and sensors that underlie the integrated air defense network shared by the United States, Israel, and Gulf partners. If true, the implications would be dire. Operating without the “eyes” that the American military relies on to identify and mitigate threats, U.S. forces and assets would be much more vulnerable than previously understood.
I don’t believe that’s accurate. The radar systems act as a mesh network, and if it’s patchy en route, it becomes harder to acquire a possible interception solution. This is especially the case when some of the longest range systems (such as THAAD) are out of commission. Then you need to rely on shorter range systems, such as Patriot missiles, with a shorter and lower intercept range. The article goes over this, and explains how the different systems act as multiple layers of air defense.
A loss of long-range radar and interception ability won’t look like a gaping hole with missiles flowing through. Instead, there will be more last-second attempts to shoot incoming missiles down, with a lower success rate than the long-range alternatives.
