The submunition in the CBU-52 is softball sized and effective against soft-skinned targets. The dispenser holds 220 of the submunitions and is best used against personnel or light-skinned vehicles. The CBU-52, loaded with 220 antimaterial, antipersonnel bomblets, weighs 785 pounds and can be used with a variety of proximity fuzes or the mechanical MK-339 timed fuze. The submunition is a 3.5-inch spherical bomblet weighing 2.7 pounds with a 0.65-pound high-explosive warhead.

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.
