Description: The Boeing GBU-57/B Massive Ordnance Penetrator (MOP) is a 30,000-pound penetration weapon sponsored by the Defense Threat Reduction Agency (DTRA) . It is intended to defeat a set of hard and deeply buried targets such as concrete bunkers and underground facilities. The MOP weapon has been designed to be released from high altitudes by the US Air Force B-2 and B-52 bombers. Its navigation system builds around the GPS and its warhead is made of more than 5,300 pounds of explosive. The MOP was first loaded into a surrogate bomber in December 2007 and was ready for deploymet by the end of 2010.

In early 2015 the US Air Force tested a new version of the MOP fitted with upgraded electronic countermeasures to prevent jamming of its guidance system. The improved version is intended to engage heavily fortified underneath bunkers using two successive MOP bombs thus requiring high accuracy. This new capability may be intended against Iran's Fordow nuclear research facility.
