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.

GBU-24: This GBU-24 bunker buster is tiny in comparison to the new MOP
The MOP is 20 feet long and can penetrate bunkers up to 200 feet before exploding. At 15 tons, the MOP is a third heavier than the previous "mother of all bombs", the GBU-43/B Massive Ordnance Air Blast bomb, which was only 10.5 tons. The MOP also packs a whopping 5,300 lbs of explosives, which is 10 times the amount its predecessor bunker-buster, the BLU-109, carried. Basically, it's massive.

The push for accelerated deployment is due to the increased perceived nuclear threats from Iran and North Korea. It's believed that many of their nuclear programs could be in development underground, below levels of current bunker-busting bombs' range. The Pentagon intends the rapid deployment to send a message that the United States is tweaking strategies to address new threats. And nothing is more American than advertising the sheer size and tonnage of the bombs hanging below our jets.

once we used the city moab, now we use the tool mop....

Legions of CHUDs cower in fear.

Israel will love this one. When they decide to make a deposit into the Iranian nuke facility. I can see them licking their chops.

New bombs dropped from old jets. The B52 is the best deal the taxpayer has ever gotten on any military equipment.

awesomenezz.... time to use this against iran/norko nuclear bunkers.

like your common sense vision on most of these posts, meyaht, and although the past generations carriers might be an argument, having allowed us the luxury of being able to fight wars on foreign soil rather than our own, with a fleet that served in two world wars. Sheer fear and self preservation are what the Buff backed, the knowledge already in mind of their potential to carry nukes. Consider that the mind boggling amount of all ordinance is as you say, the bottom line. I must remind that most of the bombs dropped were highly controversial-then and now. While I must agree the raw use factor being substantial, I must consider real worth provided as the determinant factor.

I'm curious how well this works. I've heard that many bunkers are far far deeper than any bomb could reach. I also heard that most of the bunker busting bombs used in the Iraq war did not work. The china was still on the shelves (next to the Swedish, German and French electronic equipment.)

But booms are always fun.

Even if some of the bunkers are deeper than a single MOP can reach, two or three dropped successfully onto the same crater will probably, definitely finish the job I imagine. Once the soil, concrete etc is loosened up by the first one, second or third won't probably have such a hard time going deeper and deeper.

Say buh-bye, President Ahmanutjob...

I very much doubt our current "Commander-in-chief" would ever direct any US Military Force authorization to utilize this weapon against any of our enemies. He's too busy apoligizing to them for all our past successes.

I like this new Bunker buster.

@meyaht - I share your enthusiasm...LOL

@Relyeselad - Get over it! We're NOT getting into another $2 Trillion + 5000 soldier war unless we HAVE TO!

I'm very pleased and confident that President Obama will never take us to war unless all other options have been exhausted. Look how easy it was to free the american journalists in North Korea!!! Is cost taxpayers' nothing. He put and Ex-President to work. As far as apologies go, someone had to apologize for that idiot Bush. Heck... even his own party didn't want anything to do with him at their last convention. But of course, they're too proud to admit they made a colosal mistake with him. Nevermind their allegiance to their country. They always put party first. I'm sure you'd still vote for Bush anyday. Yours is a breed I can't wait till they die off.

Not for use on a Nuclear Research facility, but for "causing an incident" at a Nuclear Reactor, I offer the Department of Defense the following idea: You launch from a missile or a high-altitude aircraft, from "way far away" and from "way up there" a Telephone-pole sized "harpoon" (obviously weighing close to a ton) made of solid Tungsten Steel, sharpenened to a pin-point and using GPS guided fins to steer it. You simply drop it onto the roof of the Nuclear Reactor Containment Building, causing a meltdown (See "Chernobyl"). No explosives would be needed, therefore no explosive signature to trace from debris flung far and wide. After dropping for over 200-miles using nothing but gravity, this spear should be going so fast that in all likelyhood nobody will see it hit, and it will become hopelessly embedded/buried many hundreds of feet down. There could be no markings on this baby, and the USA could easily deny having any part in it. Besides, it would be buried beneath a site now contaminated for hundreds of years. I see nothing. I know nothing. They literally wouldn't know what hit them. Heheheh!

Please drop the first one on blaxpear's mobile home. Thank you.

SAY HELLO TO MY LITTLE FRIEND !

looks a bit like they may have used the charges from the MOAB in a new delivery vehicle-like the JDAM upgrade...

Your harpoon wouldn't be even close to invisible, Nostradamus, at that size it would look like a shooting star coming in at 300 mph, which is quite noticeable. Nor would tungsten by itself be ideal. A multilayer mesh that is designed to peel off in layers, not sections,like a lot of shirts on your arm, but each one harder to scrape away than the last, a heavier core in the truncheon, solid so it wouldn't blow out as easy as mercury...there could be something worth dropping from just below low orbit. (wouldn't want to violate a non-proliferation treaty)

I wonder how isolated from shock waves the UF6 centrifuge installation is at Nataz, Iran. Would this device be able to generate a shock wave large enough to unbalance these high speed centrifuges and make them self destruct?

You people need, an I can't stess this enough,need to read about Sam Cohen, http://en.wikipedia.org/wiki/Samuel_Cohen

It will change your outlook on the American nuclear policies forever. Look for Confessiones of the father of the neutron bomb, a free, downloadable 288 page book that will rock your world.

Nostradamus That is known as Rods from God. They are already in production.

They are also refered to as crowbars. They are beyond the devolpement stage and are in "field tests", they range in length from 100 cm to 1000 cm in length.

holy cow i want one. now how can i get a few billion dollars, hmmmmmm......

Mikereno,
Yes, indeed. Your comment is heartily endorsed. I'd like to back you up regarding your sentiments about blaxpear.

@Nostradamus: i like that idea.

@Mikereno: i second that motion.

While things that go boom are certainly high in cool factor, I can't help but wonder how many of you in favor of using this have ever been to war and have ever thought about the reality of US foreign policy. Having served in the military for 15 years, including Afghanistan, it is now clear to me why critical thinking is so valuable, and so highly discouraged both within the military and without.

First of all, while the US claims moral high ground in all affairs, we are up to our necks in involvement with brutal dictators and regimes that routinely violate human rights. The brutal dictatorships in Africa that are regularly chastised by international human rights agencies & organizations are kept in power and arms by their cooperation with US corporations. If the governments of Sudan and Chad, for example, weren't cooperating with US energy companies, we would have intervened in Darfur years ago. US media loves to paint Palestine as being solely responsible for the Israel/Palestine conflict, carefully avoiding coverage of all the racial violence, check point harassment, land confiscation/home destruction, and economic starvation wrought by the Israelis against the Palestinians. Are we really so naive about what it's like to live under an occupation? We certainly wouldn't tolerate such treatment so why should we expect anyone else to?

Secondly, the primary motivation of our foreign (and domestic) policy is the economic gain of private corporations. Even the treatment of our military supports this point. The military spends $Millions on recruitment advertising showcasing technical, skilled, or other non-combat jobs. Recruits only find out after AIT (Advanced Individual Training) that in the combat zones of Iraq and Afghanistan those non-combat positions are being filled by private contractors--leaving those "skilled" soldiers to run convoys or man check points. And that comes without the necessary equipment to keep them safe from those actively trying to dispel an occupying force from their homeland. But, as we were reminded by our former (and lackluster) SecDef, Donald Rumsfeld, "We go to war with the Army we have, not the Army we want!" Then when they return broken, either physically or emotionally, the government does everything in its power to leave them out in the cold, especially if they decide they want to leave military service.

Thirdly, who are we to point fingers and call names in the first place? We use the same psychological propaganda measures that the Nazis used against their population to turn public opinion in support of war and other foreign military operations. Our government and media propagate fear and nationalism and call it patriotism. But don't take my word for it. In his testimony at the Nuremberg War Crimes Tribunal, Hermann Goering made this statement: "Naturally the common people don't want war; neither in Russia, nor in England, nor in America, nor in Germany. That is understood. But after all, it is the leaders of the country who determine policy, and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is to tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in any country."

Our corporations exploit the natural resources of sovereign nations, ruin their environment, deprive the local population of economic opportunity (and in many cases the means to feed themselves) and do nothing to elevate or improve the local economy or standard of living. They quickly point to corruption in local government as the real culprit, but fail to admit that they willingly deal with monsters and thereby are complicit in all the atrocities they commit. When the local population rebels against this exploitation and fight for their own welfare, their very lives, we consider them terrorists. Where is the justice and moral high-ground in this?

Fourthly, has anyone even thought to question where the weight of a 30,000 lb bomb comes from if it's only carrying 5300 lbs of explosives? Needless to say it's not from a sheet metal shell or even a steel jacketed lead core. Most cars and SUVs are 15-17 feet long and weigh between 3000 and 5000 lbs. A 2009 Chevy Suburban loaded with the 5300 lbs of explosives would still weigh in at only 11,000 lbs. A Bradley Infantry/Cavalry Fighting Vehicle is roughly five or six times the dimensions of the MOP (if melted down solid) and only weighs 33 tons with all of its aluminum and steel armoring. No, that kind of weight (and at the reported low expense) can be no other than depleted (or not) Uranium.

Our government has been wily not to classify DU munitions as nuclear weapons. They've even been deceptive in claims of safety. However, the truth is that the long term and indiscriminate effects of DU munitions arguably classify them not only as WMDs but also as nuclear munitions. The UN Security Council has made several efforts to ban these weapons, always being defeated by dissenting votes of ranking members of the SC--the US, GB, France, and Germany--all of whom hold DU weapons in their arsenals.

Furthermore, our government has gone to great lengths to discredit any expert who offers irrefutable evidence of the atrocious nature of DU munitions. The best example of this is Dr. Asaf Durakovic. A nuclear scientist and former US Army medical officer, Durakovic was discredited and had his commission revoked for publishing an unfavorable review of the US use of DU munitions during the first Gulf War in 1990. His report then clearly indicated the consequences of using DU munitions which have been substantiated by over a decade of research and new evidence after subsequent use in Bosnia, Afghanistan, and Iraq (again). His research has been confirmed by other scientists and research stations in the UK. In fact, immediately following conclusion if the initial air campaign in Afghanistan, a military research station in the UK measured a significant (exponential) spike in atmospheric Uranium particle concentration. It is important to note that, given the prevailing wind currents between 30 and 60 degrees N latitude being towards the east, those particles had to first traverse most of the northern hemisphere (including the US) in order to be measured in the UK. DU particles are small enough to enter the blood stream through inhalation. Is there any wonder why cases of allergies, reproductive disorders, autoimmune conditions, cancers, and Chronic Fatigue Syndrome have sky rocketed in the US and around the world since 2001? And you all are advocating the use of the largest DU munition in existence?

Finally, look at all the scary information spread throughout the US media about "dirty bombs", or "conventional" bombs tainted with radioactive material such as Uranium or Plutonium. Simply put, the same is true of DU munitions. The only difference is that DU munitions are used by developed/industrialized nations "specifically" for their penetration qualities. The radiological contamination that follows is only secondary and thereby somehow acceptable. It reminds me of the M2 machine gunner who mows down the enemy infantryman, in violation of Geneva Conventions on War Crimes, and claims he was aiming for the radio that was strapped to the enemy's back.

It saddens me that one of the most wealthy nations in the world (well, formerly, at least) would have such a ridiculous penchant for ignorance, aggression, arrogance, cowardice, and inhumanity and yet maintain the audacity to claim to be "right", "moral", and "civilized". How desperately so much of our nation is in need of a long, hard, look in the proverbial mirror!

The Tall Boy, Grand Slam, and T12 (weighing in at 43,600 pounds) all had cases not of uranium which exceeded the weight of explosives. This is typical in earthquake and armor piercing bombs. 9,135 pounds of the 22,000 pound Grand Slam is Torpex.

Even steel, never mind tungsten, is far denser than Torpex. The self sharpening properties of uranium is not really of as much utility in this application as it is in AP ammunition. Granted, tungsten is not garbage that is just laying around like DU. Most of the cost of modern weapons lie in the guidance systems regardless.

It is not against the Geneva convention to use an M2 against personnel unless incendiary ammunition is loaded.
