The CBU-104 Wind-Corrected Munitions Dispenser is the WCMD-equipped version of the U.S. CBU-89 Gator mine dispenser. It keeps the 72 BLU-91 anti-armor and 22 BLU-92 anti-personnel mine payload while adding an inertial tail kit that corrects release errors and winds aloft, giving the Gator family a more accurate medium- or high-altitude delivery option. Public sources document the CBU-104 as a certified F-16/BRU-57 and B-1B weapon, while available conflict-use sources identify other WCMD variants rather than direct CBU-104 combat employment.
The CBU-104 is best read as a guided conversion of the CBU-89 Gator mine dispenser rather than as a separate mine payload.

WCMD replaces the tail section with an inertial guidance package, a targeting-data processor, and pop-out movable fins that correct release errors and winds aloft.
Program reporting described CBU-89/B conversions as one planned slice of the broader WCMD retrofit for CBU-87, CBU-89, and CBU-97 dispenser inventories.
The CBU-104 designation applies the WCMD tail-kit family to the CBU-89/B Gator mine dispenser. Adjacent WCMD designations use the same guided-tail concept on other tactical munition dispenser bodies.

 | Multirole fighter | Lockheed Martin said the U.S. Air Force certified the CBU-103/104/105/107 WCMD series for Block 40/42/50/52 F-16 aircraft using the BRU-57 rack. |
The CBU-104's F-16 certification is tied to the BRU-57 smart multiple carriage rack.

 | Smart multiple carriage rack | Lockheed Martin identified CBU-104 as part of the WCMD series certified for use with BRU-57 on Block 40/42/50/52 F-16 aircraft. |
Available public conflict-use sources support keeping this page as a relationship-only record. UK parliamentary reporting stated that CBU-104 Gator bombs had not been dropped over Afghanistan. Human Rights Watch and WCMD designation summaries discuss operational WCMD use in Afghanistan and Iraq, but the directly named combat examples in those sources identify CBU-103, CBU-105, or CBU-107 rather than a CBU-104 release in a named conflict.
