2003: A B-2 Spirit released two newly upgraded 5,000-pound live weapons Aug. 14 in a test by the B-2 Global Power Bomber Combined Test Force. The weapons were released over the Utah Testing and Training Range at Hill Air Force Base, Utah, marking the first successful drop of live GBU-28 B/B series weapons. A live drop is the last dedicated flight for the developmental test and evaluation phase of the program. The GBU-28 B/B is an enhanced version of the GBU-28 A/B, designed specifically for the B-2. The GBU-28 is a GPS-guided and laser-guided weapon, deployable in all weather conditions. (USAF Image, 1989)
