The Massive Ordnance Penetrator Will Be the Largest Non-Nuclear Bomb Ever

And the Pentagon hopes to deploy it next year

The Pentagon is trying to speed up the deployment of an ultra-large bunker-busting bomb, which would constitute the largest non-nuclear bomb the U.S. has ever used. The Massive Ordnance Penetrator, or MOP, is a 30,000-pound bomb that would dive deeper than any previous bomb, and could be strapped to B-2 or B-52 bombers by July of 2010.

Do You Have a Bomb-Defusing Ray Gun to Spare? The Navy Would Like a Word

Despite years of failure, the Navy continues to look for futuristic solutions to the IED problem

The U.S. Navy is still looking for an energy ray to defeat IEDs. However, unlike previous attempts, the new technology they're dreaming of would render the explosives inert, rather than prematurely detonate them.

Improvised Explosive Devices (IEDs), also often referred to as roadside bombs, have been the deadliest weapon used by anti-U.S. forces in both Iraq and Afghanistan. The devices prey on the U.S. military's dependence on roads for logistics; they target supply convoys and patrols alike. Unfortunately, many of these mines can't distinguish between U.S. Marines in a Humvee and an Iraqi or Afghan family in an Opel, leading to many civilian deaths as well.

Bombs Away?

Scientists cast doubt over the Pentagon’s plan to build a new nuclear bunker buster

According to the U.S. Department of Defense, hundreds of
underground bunkers in enemy territories serve as weapons silos, command
centers and safe havens for rogue leaders. Drilled several hundred feet or deeper into the ground, many of the hideouts are far beyond the reach of conventional weapons. The Pentagon’s solution: Build a super-slim bomb called a Robust Nuclear Earth Penetrator (RNEP) capable of piercing 20 feet of solid rock and unleashing shock waves on par with a magnitude-7 earthquake.

This fall Congress will decide whether to approve $8.5 million to complete a
