GBU-37 GPS-Aided Munition
The GBU-37 Global Positioning System Aided Munition was developed for use with the B-2 Bomber. The bomb can penetrate hardened targets or targets buried deep underground. The first all-weather precision-guided bunker buster, it became operational in 1997. It has been replaced on the B-2 by the 5,000-pound GPS-aided/INS-guided GBU-28.
