Which JDAM is configured with the MK84 bomb and tail kit KMU-556?

The GBU-31 V1 is indeed the variant of the Joint Direct Attack Munition (JDAM) that is combined with the MK84 bomb and the KMU-556 tail kit. This specific configuration allows the MK84, which is a 2,000-pound general-purpose bomb, to take advantage of precision guidance provided by the JDAM technology. The KMU-556 tail kit includes GPS/INS technology that converts the unguided MK84 bomb into a highly accurate guided weapon, capable of hitting designated targets with a high degree of precision.

Understanding weapon configurations is key, as each JDAM variant has specific capabilities and uses different types of bombs or tail kits for varying operational requirements. The other options listed refer to different bomb and tail kit combinations or different munition types altogether, which do not apply to the MK84 and KMU-556 pairing. This highlights the importance of properly identifying the correct variant based on the specific bomb and tail kit involved in its design.
