In June, when the United States conducted Operation Midnight Hammer—a series of strikes against Iranian nuclear targets—it did so with two key pieces of exquisite hardware: the GBU-57 Massive Ordnance Penetrator, a large bomb designed to penetrate hardened and deeply buried targets, and the B-2 Spirit strategic bomber. But how does the GBU-57 actually work? How is it designed? And what’s it like to fly this type of long-range bomber mission in a B-2?

To examine those questions, John Amble is joined on this episode by Dr. Melvin Deaile. He teaches at the US Air Force’s Air University and is a retired Air Force colonel and strategic bomber pilot with operational combat experience in the B-2. This makes him uniquely suited to both share his perspective on one of the Air Force’s most unique munitions and describe the experience of flying a strategic bomber in action.
