Which Cluster Bomb Unit (CBU) uses the Wind Corrected Munitions Dispenser (WCMD)?

• A. CBU-97 SD
• B. CBU-103B/B
• C. CBU-87 C/B
• D. CBU-89/B

Answer: (B)

Wind drift is a major factor for cluster bombs released from aircraft, and the Wind Corrected Munitions Dispenser adds a guidance tail with small wings and GPS/INS guidance to compensate for that wind, dramatically improving hit accuracy. This capability is implemented on the WCMD-equipped variant of the CBU-97 family, specifically the CBU-103/B. That’s why this unit uses WCMD. The other cluster bombs listed are older or unguided designs that disperse submunitions without the wind-correcting tail kit, so they don’t employ WCMD.
