DoD has recently asked permission to reallocate funding for a number of programs from these programs: http://www.defensetech.org/ To these programs: The line that stood out was $12 million for Massive Ordnance Penetrator. The MOP is designed to go deeper than any nuclear device to take out a bunker. The idea is to render a bunker unusable rather than to totally destroy it. This munition is intended to take out 25% of a bunker. It is a 30,000 pound weapon. It is expected to penetrate 60 meters of concrete/earth.
