The CBU-58 is loaded with 650 bomblets. These bomblets contain 5-gram titanium pellets, making them incendiary and useful against flammable targets. This cluster munition is optimized for soft skinned targets to include personnel and light skinned military vehicles. The dispenser holds 650 of the baseball sized bomblets to be dispersed over a wide target area.
The CBU-52, -58 and -71 all use SUU-30 dispensers, a metal cylinder divided longitudinally. One-half contains a strong back section that provides for forced ejection and sway-bracing. The two halves lock together. Four cast aluminum fins are attached at a 9~degree angle to the aft end of the dispenser and are canted 1.25 degrees to impart spin-stabilized flight. When released from the aircraft, the arming wire/lanyard initiates the fuze arming and delay cycle. At fuze function, the fuze booster ignites and unlocks the forward end of the dispenser. Ram air action on the dispenser forces the two halves apart, instantaneously dispensing the payload and allowing the bomblets to spin-arm and self-dispense. A total of 17,831 were expended during the Gulf War.
