The GBU-28 is a 4,000-pound (1814.3 kg) class laser-guided "bunker busting" bomb produced originally by the Watervliet Arsenal, Watervliet, New York. It was designed, manufactured, and deployed in less than three weeks due to an urgent need during Operation Desert Storm to penetrate hardened Iraqi command centers located deep underground. Only two of the weapons were dropped in Desert Storm, both by F-111Fs.[2] One GBU-28 was dropped during Operation Iraqi Freedom.[3] It was designed by Albert L. Weimorts.[4][5]
