Haaretz Investigation: Iran's Cluster Missiles Penetrated 27% of Israeli Air Defenses in Final War Days

A Haaretz investigation documents a sharp degradation in Israeli missile defense effectiveness as the Iran war progressed. While only 5% of Iranian missiles hit Israel early in the conflict, that figure rose to 27% in the final five days, with four of five successful strikes being cluster missiles. Half of all Iranian missiles fired contained cluster munitions designed to release bomblets at high altitude to overwhelm defensive systems. One cluster missile alone dropped 70 submunitions across central Israel. The data challenges pre-war Israeli intelligence assessments of Iranian missile capabilities and suggests Iron Dome and Arrow systems cannot sustain effectiveness under extended bombardment.

Analysis
This data answers the question posed in prior cycles: Israeli intelligence did miscalculate Iranian missile capabilities, and the miscalculation widened as the conflict progressed. The 5%-to-27% penetration rate implies Iran was adapting faster than Israeli defenses could counter. Cluster munitions releasing bomblets above the engagement ceiling of point-defense systems like Iron Dome represent a tactical innovation that US CENTCOM should assume will proliferate. The single-source Haaretz investigation draws on IDF data that may itself be selectively released; the actual penetration rate could be higher than officially acknowledged, particularly if classified intercepts failed silently rather than visibly.
