The GBU-15 Guided Bomb Unit is a U.S. electro-optical glide bomb built around a 2,000-pound Mk 84 or BLU-109 bomb body, with television or imaging-infrared guidance and a man-in-the-loop data link. U.S. Air Force, museum, and Air University sources document F-111F use in Desert Storm, F-15E drops during Operation Deliberate Force, enhanced GPS/INS-equipped GBU-15 combat employment in Operation Enduring Freedom, and current deployment only from the F-15E Strike Eagle.
