Understanding the Recent Dynamics of Israel’s Iron Dome and Iranian Missile Strategy
The Iron Dome was widely celebrated as a central pillar of Israel’s air-defence architecture, with the stated ability to track, identify and destroy incoming bombs. But recent events raised doubts about its capabilities, particularly in light of a massive missile bombardment from Iran. The blog post discusses the intricacies, in particular how the logic of missile warfare has changed and what it means for Israeli defence capabilities.

The Iron Dome: An Overview
The Iron Dome forms the first (lowest) layer of Israel’s multilayer air defence system, designed to respond to aerial threats, namely short-range airborne projectiles. Iron Dome is complemented by other layers of this complex defensive system including David’s Sling and the aerial defence system known as Arrow. Its designed intercept range is intended to target rockets and other smaller airborne projectiles at a distance of 4 to 70 kilometres. The next layer, David’s Sling, extends that range to around 300 kilometres, possibly more, to target longer-range rockets and cruise missiles. The Arrow system, forming the highest layer of Israel’s air defence system, is designed to intercept medium to long-range ballistic missile threats at a distance of 2,400 kilometres.
Recent Attacks: A Shift in Strategy
The results after a major attack in April earned wide praise for the Iron Dome’s performance. This new assault, from Iran, paints a different picture. The reports from the field suggest that many Iranian missiles penetrated Israel’s complex air defences, prompting a more critical assessment of the system’s capabilities this time around.
Intensity of the Attack
The latest barrage was reportedly roughly twice as ‘large’ as previous ones. And this makes sense. If you shoot three times as many missiles, you’re going to have three times as good chance that at least one will get through.
Type of Projectiles Used
Also important is the category of missiles that Iran uses. In the previous attack, Iran launched mostly drones and rockets at Israel. Those missiles took hours to travel from Iran to Israel. A drone from the previous attack took about nine hours on its way to Israel where it encountered the Iron Dome, giving the system plenty of time to intercept the missile. On this occasion, Iran launched 180 ballistic missiles. Ballistic missiles travel much faster than drones and rockets. These and other reasons make them much harder to intercept.
Missiles in the arsenal include the medium-range Shahab-3 as well as the hypersonic Fateh-1, which is capable of flying five times faster than the speed of sound, thus reaching Israeli territory in just 12 minutes. This sharp reduction in flight time means that Iron Dome’s interception time is significantly more challenging.
Lack of Warnings
Second, surprise was a factor. Iran had warned in advance of the previous missile attacks, giving Israel time to prepare defences. This time there were no warnings.
Because there was no warning, the air defence systems could not be fully engaged and more Israeli targets were successfully struck by the missiles, the harder target The element of surprise was tactically effective for Iran in its latest attack.
The Cost of Defense
A third issue concerns cost. The price of intercepts can be extremely high. One Arrow costs $3.5 million, and a David’s Sling about $1 million; by contrast, Iranian missiles cost only around $100,000 apiece. This economic differential is a factor in the strategic calculus on both sides: the harder an Israeli defence becomes, the more cost-efficient are Iranian missiles for overwhelming Israeli defences.
Implications for Future Conflict
The results of this recent attack drive home a key point: Israel’s defences, even with its sophisticated array of technologies, are not impermeable. When the opposing side has the right weaponry and the right modelling on how to strike from the air, it can break into Israeli airspace. Iran’s military has demonstrated its determination to learn from past events. It has shifted the battleground from the slower drones of the past to faster ballistic missiles.
Estimates of the sort put Iran’s arsenal at around 3,000 ballistic missiles, so they’re certainly not lacking for options if they decide they need more. This might be enough to offer a form of deterrence, but escalation dynamics loom large.
Conclusion
The recent missile strikes on Israel have highlighted the kind of complex and constantly shifting military environment that Israeli forces are likely to face in the years to come as their enemies adjust their tactics and technologies. Israel’s use of the Iron Dome system and its associated military strategies and policies will serve as an indicator of how military strategy and defence policies elsewhere in the region will be affected.
