The GBU-12 is a laser-guided bomb available to the AV-42C, F/A-26B, F-45A, T-55 and EF-24G. It requires constant laser designation of a target for accurate deployment, similarly to the AGM-114, and uses the same HUD symbology as GPS-guided bombs. It is one of two bombs effective against moving targets, the other being the GBU-53.
The GBU-12 features a single setting within the EQUIP menu, determining the guidance method of the bomb.
Targeting Mode:
Laser - The standard Laser guidance mode.
Dumb - Entirely disables Laser guidance on the bomb, making it function identically to a Mk. 82. A regular bomb reticle will also appear instead of the guided bomb reticle.
The GBU-12 is chiefly used as an asset in Close Air Support tactics. In comparison to an Air-to-Ground Missile, the GBU-12 can be equipped in greater quantity and carries a much larger payload, but has a more time-consuming deployment process. By designating the center of a group of hostile units, the GBU-12 is able to dispatch targets with a single bomb.
If the TGP's laser deviates from its target, the GBU-12 will likely maneuver far off-course and fail to damage its intended target. Attempting to deploy the GBU-12 in a high-threat environment is not recommended, as defensive maneuvering of the aircraft risks breaking the TGP's target lock.
Due to the position of the TGP on the aircraft, it is recommended to establish a left-hand orbit around the target when flying the F/A-26B. Other fixed-wing aircraft do not share this restriction.
As with all guided bombs, the GBU-12's guidance package can be disabled in the MFD's EQUIP page, allowing it to function akin to the Mk. 82 unguided bomb.
