GBU stands for Guided bomb unit, a weapon and military equipment abbreviation.

US designation prefix for guided bombs, applied to laser-guided Paveways, GPS-guided JDAMs and large penetrators. Examples include the GBU-12, GBU-31 and GBU-57. The number identifies the specific kit and bomb combination.

Example: The F-16 carried two GBU-12s and a targeting pod.

Usage notes

Unguided general-purpose bombs carry Mk numbers such as the Mk 82 500-pound bomb; adding a guidance kit creates a GBU designation. Related prefixes include CBU for cluster bomb units and BLU for bomb live units, the bomb bodies themselves.
