Haaretz Analysis Reveals Increasing Penetration of Iranian Missiles in 40-Day Israel-Iran War

A Haaretz investigation found that one in four Iranian missiles fired at Israel during the last week of the 40-day war penetrated air defenses. Penetration rates rose from 5 percent at the war's start to 27 percent in the final five days. Four out of five missiles that struck sites in Israel were cluster missiles.

Missile Penetration Rates Rose During Conflict Haaretz reported that one in every four Iranian missiles fired at Israel in the last week of the 40-day war penetrated Israel's air-defense systems.

As the war progressed, the number of missiles that penetrated Israel's air defenses and caused damage increased. The war between Israel and Iran lasted 40 days. At the beginning of the war, 5 percent of missiles launched from Iran hit sites in Israel, according to a Haaretz investigation.

In the last five days of the war, 27 percent of missiles launched from Iran hit sites in Israel. Four out of five missiles that struck sites in Israel were cluster missiles.

Early War Phases Showed Lower Impact The initial phase of the conflict saw limited success for Iranian missile strikes, with only 5 percent penetration.

This rate reflects the effectiveness of Israel's air defenses at the outset. Haaretz's analysis highlights how these defenses held against the majority of launches early on.

Escalation in Final Stages By the war's conclusion, penetration reached 27 percent in the last five days, indicating a shift in defensive capabilities.

The overall last-week figure of one in four successful penetrations underscores this trend. Cluster missiles accounted for four out of five hits on Israeli sites throughout the period.

Types of Missiles Involved Haaretz investigation determined that cluster missiles were predominant among those causing strikes.

This composition affected the nature of damage inflicted. The 40-day duration provided a timeline for observing these patterns.

Potential Impact

  1. 01

    Overall 40-day conflict duration allowed for observed escalation in missile effectiveness.

  2. 02

    Increased damage to Israeli sites in later war stages due to higher penetration rates.

  3. 03

    Predominance of cluster missiles likely amplified area effects of strikes.

  4. 04

    Shift from 5 percent to 27 percent penetration may strain air defense resources over time.
