The CBU-71 is loaded with 650 BLU-68/B incendiary submunitions which use titanium pellets as the incendiary agent. The bomblet has two separate kill mechanisms, one fragmentation, the other incendiary. Both incorporate a time delay fuze, which detonates at random times after impact.
The CBU-71/B is very similar to the CBU-58, carrying 650 baseball-sized bomblets. However, the CBU-71 submunitions have a random delay fuzing option making this cluster weapon great for area denial against soft- skinned targets (light or no armor).
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.
