The GBU-39 Small Diameter Bomb (SDB) is a 250 lb (110 kg) precision-guided glide bomb that is intended to provide aircraft with the ability to carry a higher number of more accurate bombs. Most US Air Force aircraft will be able to carry (using the BRU-61/A rack) a pack of four SDBs in place of a single 2,000 lb (907 kg) bomb. The SDB relies on the Global Positioning System to provide navigation to the target. Furthermore, the small size of the bomb allows a single strike aircraft to carry more of the munitions than is possible using currently available bomb units.
