![]() Some primary differences between the older and newer designs revolve around their weight and internal navigation system. According to James Culliton, the GBU-72 Program Manager, “Lethality is expected to be substantially higher compared to similar legacy weapons like the GBU-28.”Ī few tests of the new design were executed in 2021, and new trials are expected to continue throughout 2022. Bunker Busters TodayĪ new and unfinished version of the bunker buster bomb known as the GBU-72 is expected to be more potent than its predecessors. However, it is not even half the size of the GBU-28, only weighing up to 2,000 pounds, making it easier to carry. To combat this, a smaller twin bomb known as the BLU-109 bunker buster bomb is used for the same purpose. Given its immense weight, smaller military-grade aircraft, such as the F-15E Eagle, can only carry one at a time. In previous trials, the GBU-28 has pierced 100 feet into the ground and has penetrated up to 20 feet of solid concrete. Not only that, but they are also dropped from a predetermined height of around 20,000 feet in the sky. Many of you may be asking, “How deep can a bunker buster go?” These are incredibly heavy bombs with narrow points. Once the final product was originally completed, it was coined the GBU-28, weighing approximately 4,400 pounds and standing at a whopping 19 feet tall. There are tall retractable fins at the end of the bomb to help keep it stable during flight. Fastened on the nose of the bomb is a laser guidance system, which casts light upon the designated target. Inside, there is over 600 pounds of tritonal explosive, a mixture of 80% TNT and 20% aluminum powder. bunker buster consists of a 16-foot casing and an artillery barrel that is 14.5 inches in diameter and covered with solid steel. This was until the Air Force implemented the bunker buster in the NATO-led bombing campaign against Serbia in 1999 and during the early phases of the Afghanistan and Iraq missions in 20. They also became the topic of discussion after it was discovered that Iraqi underground dugouts were so deep in the ground that no normal bomb could reach them. ![]() Recent prototypes for bunker buster missiles began around the bombing campaign against the Federal Republic of Yugoslavia.
