The Wind Corrected Munitions Dispenser or WCMD system is a US tail kit produced by Lockheed Martin for use with the 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 - 30,000 for CEM and 5,000 each for Gator and SFW - at a cost of US$8,937 per unit.^[1]

When fitted with the WCMD the CBU-87 Combined Effects Munition, GBU-89 GATOR and the CBU-97 Sensor Fuzed Weapon are respectively known as the CBU-103, CBU-104 and the CBU-105; the latter 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.
