Sdb
The Small-Diameter Bomb (SDB) is a 250-pound-class guided bomb that is intended to provide aircraft with the ability to carry more weapons per sortie, thus increasing the number of kills possible.
Two variants are being developed. One version of the SDB is equipped with INS/GPS guidance which makes it ideal for fixed/stationary targets such as fuel depots, bunkers etc. The second variant includes a thermal seeker with automatic target recognition features which makes it ideal for striking mobile targets such as tanks, vehicles and mobile command posts.
The small size of the bomb allows a single strike aircraft to carry more of the munitions than is possible utilizing currently available bomb units. It is planned for integration on the F-15E Strike Eagle, with future integration on the F/A-22 Raptor, the F-35 JSF, the F-16 Falcon, the A-10 Warthog, F-117 NightHawk, the B-1 Lancer, the B-2 Spirit and the B-52 Stratofortress. Other aircraft may also receive the necessary upgrades.
The SDB carries approximately 50 lbs of High Explosive, yet because of its design it has the same penetration capabilities as the 2000 lb BLU-109. During demonstrations, the SDB has successfully penetrated more than 6 ft of reinforced concrete.
