The CB470 is a cluster bomb of South African origin. The Alpha bomblet was developed in Rhodesia in the 1970's. When Rhodesia became Zimbabwe the designers moved to South Africa and created the CB470 bomb for use with the existing Alpha bomblet.

The CB470 is a cluster bomb with a unique design. The conventionally shaped dispenser has been created around the existing round Alpha bomblet. A total of 40 bomblets are carried and each bomblet is provided with its own ejection door. Upon release the fuze each radial row of four bomblets with 0.8 second interval in order to maximize area of effect. The bomblet will first bounce on the ground, even on water or mud, before exploding mid air for increased fragmentation range.

Each of the 40 bomblets has a RDX/TNT filling and will produce fragments that are effective against personnel, soft skin vehicles and other unarmored targets. A single CB 470 has a 70 m wide and 250 m long shrapnel footprint. When dropped at speeds of 850 to 1.000 km/h the CB470 can be safely dropped from altitudes as low as 25 meters.

In Rhodesia the Alpha bomblets were carried by bomber aircraft. They were suspended in baskets in the bomb bay. The CB470 can be fitted to nearly every fighter or light strike aircraft of both Western and Soviet origin. In South African service it is used on the Impala Mk II, Mirage F-1AZ and Cheetah.

The Alpha bomblet was used in Rhodesia and quantities may remain in Zimbabwe. South Africa adopted the CB470 eventually and it has been exported to Iraq and possibly other nations.
