Iran Rejects U.S. 15-Point Ceasefire Proposal as War Continues – State Media Reports March 2026

**Introduction**  

Since the escalation of the Iran-Israel war on 28 February 2026, Iran has increasingly equipped its ballistic missiles with cluster warheads. These munitions are creating a serious challenge for Israel’s advanced air-defense systems, including Iron Dome, David’s Sling, and Arrow. Instead of a single large warhead, cluster munitions open high in the atmosphere and release dozens of smaller bomblets, saturating a wide area and making complete interception extremely difficult.

**What Are Cluster Munitions?**  

Cluster munitions disperse 24 to 80 small explosive submunitions (bomblets) over a radius of up to 10 kilometers. Each bomblet contains roughly 2–5 kg of explosives. While less powerful individually than a conventional warhead, the swarm effect causes widespread damage, overwhelms defenses, and increases civilian risk.

**Iranian Missiles Using Cluster Warheads**  

- The **Khorramshahr** (especially Khorramshahr-4) can release up to **80 bomblets**.  

- Other missiles such as **Qadr**, **Emad**, and **Ghadr** are also being fitted with cluster/cargo warheads.  

- Israeli assessments indicate that roughly **half** (and in recent waves, even more) of all ballistic missiles launched by Iran since late February 2026 have carried cluster munitions.

**How These Munitions Are Penetrating Israeli Defenses**  

1. **Saturation Attack** — One missile creates dozens of small targets that are hard for Arrow and David’s Sling to engage simultaneously.  

2. **High-Altitude Release** — The warhead opens far above the optimal interception zone, allowing bomblets to scatter before Iron Dome can respond effectively.  

3. **Interceptor Dilemma** — To conserve expensive interceptors, the Israeli Air Force has had to selectively ignore some bomblets.  

4. **Documented Penetrations** — At least **19 cluster-equipped missiles** have penetrated Israeli airspace, with impacts reported in Tel Aviv, Ramat Gan, Holon, and other central areas. Recent strikes (including March 17–24, 2026) have caused civilian casualties and damage to buildings and infrastructure.

**Strategic and Humanitarian Implications**  

- **Military Effect**: Cluster munitions allow Iran to achieve area saturation at lower cost and test the limits of Israel’s layered defenses.  

- **Humanitarian Concerns**: These weapons are indiscriminate and often leave unexploded bomblets, raising questions under international humanitarian law. Israel has described the attacks as deliberate targeting of civilian zones.  

- **Israeli Response**: The IDF is upgrading interception algorithms, increasing interceptor production, and adjusting tactics to counter this threat.

**Conclusion**  

Iran’s use of cluster munitions represents a tactical shift in the 2026 conflict. By converting ballistic missiles into saturation weapons, Iran is successfully challenging Israel’s world-class air defenses and causing real damage on the ground. The situation continues to evolve rapidly.
