Iran’s Cluster Munitions: How They Work & Why They Penetrate Israeli Defences

What are cluster munitions?

Cluster munitions are weapons that break open in the air and release many small bombs (submunitions).

Instead of hitting one target, they spread damage over a wide area.

How Iran is using them

Iran is firing ballistic missiles carrying cluster warheads at Israel.

Each missile can release 20–80 small bombs mid-air.

Many recent attacks include these types of weapons.

Why they are hard to stop

Israeli systems like Iron Dome must destroy the missile before it opens.

Once it breaks mid-air, dozens of small bombs spread out, making interception almost impossible.

This is why some attacks bypass advanced air defences.

What makes them dangerous

They cover a large area, increasing chances of civilian damage.

Some bomblets may not explode immediately, creating long-term danger.

Why Iran is using them (strategy)

To overwhelm Israel’s defence systems by increasing the number of targets.

To cause wider impact rather than precise strikes

To increase pressure on civilians and defence resources

Legal and global concerns

Cluster munitions are banned by many countries due to their indiscriminate nature.

However, Iran and Israel are not part of the ban treaty.

Final Understanding:

Iran’s cluster munitions are effective because they split into many small bombs mid-air, making them very difficult to intercept and allowing them to penetrate even advanced defence systems like Iron Dome.
