Which GBU variant is associated with the MK 82 and tail kit KMU-572?

The GBU-38 variant is specifically designated for use with the MK 82 general-purpose bomb and is fitted with the KMU-572 tactical tail kit. This combination allows for precision bombing capabilities while maintaining the payload characteristics of the MK 82. The KMU-572 provides enhanced guidance and accuracy through a GPS/INS (Global Positioning System/Inertial Navigation System) guidance system, transforming the standard unguided bomb into a precision-guided munition.

Other variants, while they may utilize the MK 82 in different capacities or configurations, do not specifically match with the KMU-572 tail kit in the same way that the GBU-38 does. This makes the GBU-38 the correct choice when discussing its association with the MK 82 and the KMU-572.
