The "Massive Ordnance Penetrator" Bunker Buster

This NCNK Issue Brief gives a brief overview of the Massive Ordnance Penetrator (MOP) 'bunker buster,' which is being developed for the purpose of putting 'hard and deeply buried targets (HDBT) 'at risk.' Research on MOP, a conventional weapon, was funded when research and development of the 'Robust Nuclear Earth Penetrator' met with congressional resistance in 2004. In 2009, development of MOP was accelerated. DPRK HDBT were named as a possible target of the RNEP and are assumed to be a target of the MOP as well. This issue brief was last updated December 14, 2009.
