GBU-39 Small Diameter Bomb (SDB) Explained
Published on Sep 21, 2017 AiirSource Military

"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 small size of the bomb allows a single strike aircraft to carry more of the munitions than is possible using currently available bomb units."

Good weapon. Standoff range, , low collateral damage, some hard target penetration ability and potential to quadruple the number of targets engaged in each sortie. The SDB-II will vastly enhance the USAF's anti-armor capability. There will be no active protection system that will defeat a vertically diving 250lb munition.

I imagine it is also very useful for drone use.
