The GBU-37 (Guided Bomb Unit-37) Global Positioning System Aided Munition (GAM) 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.[1] [2] It has been replaced on the B-2 by the 5,000-pound GPS-aided/INS-guided GBU-28.
The GPS Aided Target System (GATS) is a B-2 targeting system that makes it easier to find targets, even in bad weather. It uses the B-2's GPS and radar abilities together to pinpoint targets very accurately based on where the B-2 is right now. This helps the B-2 bomber hit targets more precisely.
