30,000-Lb. Bomb On Fast Track For Deployment

coondoggie writes "Published reports today say the Pentagon is rattling swords in the direction of North Korea and Iran by speeding the development a 20-foot, 30,000-lb bomb known as Massive Ordnance Penetrator. This weapon is intended to annihilate underground bunkers and other hardened sites (read: long-range missile or underground nuke development) up to 200 ft. underground. The Defense Threat Reduction Agency, which has overseen the development of this monster since 2007, says it is designed to be carried aboard B-2 and B-52 bombers and deployed at high altitudes, from which it would strike the ground at speeds well beyond twice the speed of sound to penetrate the below-ground target." Reuters has more specifics on the MOP's chances for deployment by 2010, and the detail that the bomb's load of explosives weighs in at 5,300 lbs.

    Sweden, maybe.

    It's certainly not the U.S., what with all the wars it's been involved in in just the last century.

    But you say "allows us" as if the U.S. is exactly what you mean - and the bomb TFA is about is a U.S. weapon - so I must draw the conclusion that you're living under the delusion that the U.S. is "peaceful and civilized", with "the best technology, industry, and economy[!]".

  4. Barnes Wallis Reinvented...again! by RobHart · · Score: 5, Interesting

    This is really a reinvention and extension of 1940's British technology. Barnes Wallis (of the bouncing "Dam Buster" bomb fame) designed a 5 tonne bomb (Tallboy) in 1943. The larger 10 tonne bomb (Grand Slam) was introduced in early 1945. It was dropped from a Lancaster bomber (by 617 squadron - the Dam Buster squadron) from about 20,000 ft and was close to sonic (320 m/s) when it hit the ground. It was designed as a penetrator, only detonating when well underground. It was used with devastating effect against the German U Boat pens, canals, bridges and viaducts where the "earthquake" effect of a deep explosion undermined foundations. The Grand Slam used 4,144 kg of explosives (Torpex)which is considerably more than the heavier bomb proposed by the US DoD with an earth penetration design depth of 40m. I would imagine that the higher impact speed of the US bomb requires a much stronger casing, but I am surprised at the small ordinance load. It is interesting to note that (as with much British technology) design data for the Grand Slam was shared with the US and a US version was made, but not (as far as I am aware) used in WWII. RobHart

    The tunnel system they had in the border areas is the king showing in their hand. As far as a paranoid North Korean is concerned, that was what assured destruction and kept the US from making the first strike. A nutty concern, of course, but let's face it, those North Koreans are a nutty bunch.

    As a guy born in a country whose people were similarly demonized just two decades ago (USSR), I have to chime in.

    North Koreans are not "a nutty bunch". They are people just like me and you, and most of them would rather prefer to be left alone and live their lives in peace. Have a good home, marry a nice guy/girl, have kids, that sort of thing. They most definitely don't dream of nuclear clouds over Manhattan. They might be worried about the kind of thing TFA is about, but mostly because they don't want war (which tends to screw people's lives in a major way, especially when you're on the losing side).

    The "nutty bunch" are the country leaders. And keep in mind that your average North Korean most likely doesn't feel the total, overwhelming kind of love towards his dear Glorious Leader that newspapers tell him he should have. By all accounts from tourists who visited NK, people there know how poor and oppressed they actually are, if not in specific things, then at least in general feeling.

    No.3 Commando was very anxious to be chums with Lord Glasgow, so they offered to blow up an old tree stump for him and he was very grateful and said don't spoil the plantation of young trees near it because that is the apple of my eye and they said no of course not we can blow a tree down so it falls on a sixpence and Lord Glasgow said goodness you are clever and he asked them all to luncheon for the great explosion.

    So Col. Durnford-Slater DSO said to his subaltern, have you put enough explosive in the tree?. Yes, sir, 75lbs. Is that enough? Yes sir I worked it out by mathematics it is exactly right. Well better put a bit more. Very good sir.

    And when Col. D Slater DSO had had his port he sent for the subaltern and said subaltern better put a bit more explosive in that tree. I don't want to disappoint Lord Glasgow. Very good sir.

    Then they all went out to see the explosion and Col. DS DSO said you will see that tree fall flat at just the angle where it will hurt no young trees and Lord Glasgow said goodness you are clever.

    So soon they lit the fuse and waited for the explosion and presently the tree, instead of falling quietly sideways, rose 50 feet into the air taking with it 1/2 acre of soil and the whole young plantation.

    And the subaltern said Sir, I made a mistake, it should have been 7 1/2 not 75. Lord Glasgow was so upset he walked in dead silence back to his castle and when they came to the turn of the drive in sight of his castle what should they find but that every pane of glass in the building was broken.

    I can think of no good ways that they are a direct threat but the fact they would trash the northern half of South Korea in the first half hour of a hot war is one deterrent. They've been training massive amounts of long range artillery of Seoul for years and that would be the first thing to go. They could kill more than a "few thousand". The destruction of of Seoul and their likely ability to overrun the DMZ means they can be very very destructive until we start bringing in the carriers and massing in our own troops. We would also have to do this while managing China's agitation and China IS a real threat.

    Incidentally trashing SK is also good for causing some financial turmoil in the rest of the world's market. So it would cost a bit of treasure. At least for awhile.

    Thanks for demonstrating just how naive you really are. Unless you purpose using nuclear weapons, please explain to me how we could destroy North Korea and be back "by lunch". They have a 1,200,000 man standing army. I don't care how great our advantages in training/tactics and technology are -- we can't simply destroy them and be back home in time for lunch. We would own the oceans and the skies near/over the battlefield and I'm sure the kill ratio would tilt heavily in our favor -- but it would eventually come down to men with rifles and when that happens there's no way to avoid a large number of American casualties. Unless you think we have some sort of technology that magically negates Mr. Kalashnikov's inventions.

    what we are discussing here is whether or not NK has the ability to do REAL damage to the U.S., which I would define as at least knocking the U.S. off of its perch as the dominant superpower

    NK has the ability to do real damage to at least one critical ally (South Korea) of the United States and perhaps another (Japan). If the United States can't be relied on to defend our friends then we will be knocked off that perch. We enjoy the position that we have because of our relationships with our allies.

    They don't have 10,000 pieces of long range artillery. According to this they only have about 10k-11k total pieces of artillery.

    They still need some sort of delivery system, unless you think they can slingshot their Fat Man sized bombs 40 kilometers. Besides, nukes are a moot point. If they use one they lose the war and the regime doesn't survive. I'd be more worried about them using one when it became apparent that defeat was inevitable and even at that I'd be worried about them using it in the tactical sense (put one somewhere in the path of an advancing American/ROK formation and wait -- no delivery system needed) than trying to get one into Seoul.

    Who said they were going to make it all the way to Seoul? Did you pay any attention at all to what I said?
