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. This is done by using a delay fuze or a hard target smart fuze (HTSF) so that the bomb doesn’t blow up before it hits its intended target. Typically, there needs to be a delay before the bomb goes off. Once it hits the ground, it impales straight through the surface. It is fundamental physics once the giant bomb is dropped from the plane, it develops a significant amount of speed, building up kinetic energy as it falls all the way down. Given that they are covered in highly hardened steel, the bombs can withstand and pierce through the Earth’s surface. They are encased in a rigid tube, are extremely heavy, narrow, and are dropped from high in the air. How Does it Work?īunker busters work for a few simple reasons. 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. Suggested read: Should We Be Worried About Russian Military Strength? Modern History of the Bunker Buster These bombs have been in effect since 1942 and continue to be updated for advanced use. Have you ever found yourself asking, “What is a bunker buster?” If so, you’re in for some answers today! A bunker buster is a bomb that can penetrate a long way underground before it explodes and can puncture through over ten feet of concrete before erupting below the surface.
