Multiple media outlets are reporting that the largest non-nuclear bomb in the United States arsenal has made its combat debut.
According to a report by CNN, the GBU-43 Massive Ordnance Air Blast, also called the Mother of All Bombs, was used to hit a cave and tunnel complex used by the Afghanistan affiliate of the Islamic State of Iraq and Syria in Nangarhar Province, Afghanistan.
Designation-Systems.net notes that the GBU-43 weighs 21,700 pounds – almost 11 tons – which includes 18,700 pounds of high explosive. It has a 40-inch diameter and is 30 feet long. The bomb is often used by the MC-130, a special operations variant of the C-130 Hercules.
One DOD official told FoxNews.com, "We kicked it out the back door."
The GBU-43's GPS guidance allows it to be dropped from high altitudes from as far as three miles away – out of the reach of some air defenses, and also allowing planes to avoid being caught in the bomb's blast radius. The London Daily Mail noted that the bomb can leave a crater almost a thousand feet wide.
The GBU-43 replaced the BLU-82 Daisy Cutter, a Vietnam-era bomb that weighed in at 15,000 pounds, and saw action in the Vietnam War, Desert Storm, and Operation Enduring Freedom, with a similar delivery method. Designation-Systems.net notes that the bomb's explosive was 12,600 pounds of a mixture of ammonium nitrate, polystyrene, and aluminum powder. The last BLU-82 was dropped in 2008.
