Wind Corrected Munitions Dispenser

The Wind Corrected Munitions Dispenser system is a US tail kit for use with the TMD (Tactical Munitions Dispenser) family of cluster bombs to convert them to precision-guided munitions. In 1997 the United States Air Force issued contracts to complete development and begin production of the WCMD, planning to modify 40,000 tactical munitions dispensers at a cost of US$8,937 per unit. The CBU-97 Sensor Fuzed Weapon when fitted with the WCMD is known as the CBU-105; this anti-armor weapon was deployed but not used during Operation Allied Force in the Kosovo War, and fired in combat during the 2003 invasion of Iraq.

The WCMD-ER program was cancelled in August 2006 due to poor test results and budgetary pressures.
