Even if B-52s have been used to test it, the B-2 Spirit stealth bomber is the only aircraft in the U.S. Air Force inventory currently capable to carry and release the heaviest U.S. bomb, the 30,000-lb GBU-57 Massive Ordnance Penetrator (MOP).
The heavy GBU-57 is a 20-foot long GPS-guided bomb believed to be able to penetrate 200 feet of concrete before exploding, thus being capable to hit and destroy deeply buried targets.
There are not many images showing the GBU-57 and even less show the MOP next to its intended platform. That’s why the top image, taken by Jim Mumaw in Jul. 2009, is extremely interesting and rare.
