Cluster bombs are complex weapons.
The following sequence explains its functioning and why bomblets cover a large area.

Step 1
The cluster bomb CBU-87 is dropped from a plane. It weighs about 430 kg and carries about 200 bomblets. This bomb can be dropped from a wide range of aircrafts from many different countries. The bomb can fly about 9 miles by itself before the bomblets are released.

Step 2
A short time before the bomblets are released the cluster bombs begin to spin. The canister opens at an altitude between 100m and 1000m. The height, velocity and rotation speed determine what area will be covered by the bomblets.

Step 3
Each bomblet is the size of a soft drink can. They deploy a little parachute that stabilizes them and makes sure that they descend with their nose down. Each of the bomblets holds hundreds of metal pieces, which can pierce armour.

Step 4
Depending on the altitude from which the bomblets were released and on the wind conditions, the bomblets can cover an area of up to 200m by 400 m.
When the bomblets explode, they cause injury and damage across a wide area. The blast of one bomblet can cause deadly shrapnel injuries of in a radius of up to 25 metres.
