Highlighted are four GBU-31 Joint Direct Attack Munitions (JDAM) guided air-delivered bombs loaded onto the belly of a U.S. F-15E Strike Eagle aircraft. The GBU-31-series consists of a 2,000-pound-class bomb (Mk 84, BLU-109, or BLU-109A/B) and a guidance kit comprising a tail unit with four articulating fins and a guidance control unit with inertial navigation system (INS) and global positioning system (GPS) functions. The GBU-31 munitions seen here are built around the BLU-109, a penetrator munition with a solid nose and a thicker, one-piece body which flares slightly at the base. It has no body welds; the heavy steel base plate is held in place by an equally robust threaded steel closure ring. The BLU-109 is painted olive drab with a single yellow band towards the nose. (ARES)
