During a recent test, a B-2 bomber delivered a live 5,000-pound GBU-28C/B bomb, sporting a new BLU-122 warhead, right on target. The GBU-28C/B provides more penetration of a target than its predecessor, the Enhanced GBU-28B/B, say Northrop Grumman officials. Northrop, which now has completed key objectives in its $5.4 million contract to integrate the C/B on the B-2, is working with Raytheon (warhead and upgraded guidance kit) on the program.
The U.S. military conducted strikes on Iranian targets around the Strait of Hormuz on May 7, as the conflict with Iran flared up again—though officials say the ceasefire remains in effect.
