“A Mushroom Cloud over Las Vegas…”

…Is what will almost, but apparently not quite, be seen on June 2. According to the Defense Threat Reduction Agency , the dust cloud from Divine Strake, a massive conventional explosion scheduled to take place at the Nevada Test Site this summer, “may reach an altitude of 10,000 feet (3,048 meters) [but] is not expected to be visible off the Nevada Test Site.”

The open-air test will ignite 700 tons of ammonium nitrate/fuel oil, good for 593 tons of high-explosives equivalent, according to the Washington Post . The Associated Press describes the test as the largest-ever open-air chemical explosion at the Nevada site – by a factor of forty. Due to the size of the blast – and its sensitive location at the home of the United States’ erstwhile nuclear test program – DTRA has taken the trouble to warn the Russians ahead of time of the upcoming test.

The test’s purpose, according to Defense News, is “to examine ground shock effects on deeply buried tunnel structures.” The WaPo describes the test as “a conventional alternative” to the politically ornery Robust Nuclear Earth Penetrator, or “nuclear bunker-buster.”

Here’s my $64,000 question, though: is this (700-ton!) explosive really a conventional “alternative,” or is it a stand-in being used to simulate a low-yield nuke?

By the way – a “strake” is “a straightedge used for leveling a bed of sand .”

Center for Defense Information science fellow Haninah Levine has been passing tips and comments to Defense Tech for months. This is his first post for the site.

(Big ups: Xeni, DS)
UPDATE 11:08 AM: “Ain’t nothing you can do when it’s Strakes on a motherfucking plain.”
UPDATE 04/03/06 12:15 PM: John Fleck, from the Albuquerque Journal, has the answer to whether Divine Strake is nuke-related. “A Pentagon budget request is explicit about its
purpose: to “improve the warfighter’s confidence in selecting the smallest nuclear yield necessary to destroy underground facilities while minimizing collateral damage.”
Meanwhile, Globalsecurity.org decodes the media gobbledygook surrounding the Divine Strake test.
UPDATE 04/03/06 5:15 PM:”In response to an email earlier today, a DTRA spokesperson confirmed that Divine Strake is the same event that is described in DTRA budget documents as being a low-yield nuclear weapons shock simulation,” the FAS Strategic Security Blog notes.

It also turns out that Divine Strake is “an integral part” of STRATCOM’s new Global Strike mission, which is normally reported to develop mainly non-nuclear capabilities against time-urgent targets. Global Strike is one of the plillars of the Bush administration’s so-called New Triad which is said to be reducing the role of nuclear weapons.

    This last question is an interesting one that’s occurred to me also: can chemical explosives be used to simulate the effect of a nuclear blast? Nuclear weapons don’t actually “explode.” They give off enormous amounts of radiation that superheat the surrounding medium. It is the air around the weapon that is “exploding.”

    A chemical weapon’s physical mass, on the other hand, IS the expanding medium. The whole mass does not explode simultaneously, but the explosion travels from the triggering mechanism outward, along with the shock wave. This tops out at around 8000 meters per second, I believe. But gamma radiation travels at the speed of light.

    The effect of a chemical explosion is a “hammer blow” while that of a nuclear weapon is to superheat the surrounding rock and the trapped gases in the rock with radiation travelling at light speed. These are very different kill mechanisms from a physics standpoint, though they might look the same on TV. I don’t think they’re trying to simulate a nuclear blast with explosives. It don’t think it can be done.

  2. Soj says:

    The other 64k question is, if it was a genuine “mini” nuclear test, who would know?

  3. Bill says:

    How you you deliver a 700 ton bomb? You can’t. So it must be to simulate someting else. Or the 700 tons is a dissinformation cover story for smaller actual tonnage but will act like a 700 ton bang.

    Veeerrryy interesting………

  4. Adam says:

    Soj,

    Anyone with a Geiger counter would know the difference.

  5. DS says:

    First off…I don’t think the bomb’s weight is 700 tons…I think it’s yield is equal to 700 tons of TNT. That means the bomb itself may actually be much smaller than you’d think. Newer nitrate based formulas have been developed in the past few years that dwarf traditional high explosives in destructive yield.
    Also, I don’t think it’s a simulation of a nuke. A nuke reaction still dwarfs the best explosives that can be produced. The sheer destructive power of a nuclear reaction remains unmatched, besides an antimatter-matter reaction…which the USAF is working on supposedly. In any case, I think this is just what it’s reported as…a very powerful test of a conventional weapon. What I do find interesting is the description of the actual weapon in the budgetary report. It mentions that it’s an “explosively shaped charge”. My guess is that it’s a warhead designed with an explosive ‘lensing’ structure so as to focus the energy in increasingly powerful stages directly down into the tunnel structure that will be the site of the test.
    Damn…I love Wikipedia.
    :)

  6. Matt Martin says:

    Or how ’bout this take–as of now, there is no military requirement for RNEP and Congress has also killed the program line. However, if the data from a 700-ton conventional test shows shortcomings vis-a-vis RNEP, wouldn’t that bolster the arguments of RNEP proponents?

  7. DS says:

    Yet another take…this may not be about the explosives at all. I’m not sure if this is going to be an air dropped test or not, but if it is, it may actually be a test of an existing warhead with a newly hardened casing to enable deeper penetration. The conventional explosives within may just be to get an idea of how far down after penetration the destructive power will extend. It would be interesting to know how deeply buried this ‘tunnel complex’ is that will be the test site.

  8. James says:

    DS: read a little more carefully. The press release specifically says the device is “700 tons of ammonium nitrate and fuel oil,” approximating 593 tons of high explosive. No aircraft can lift 700 tons, therefore the device is being emplaced.

    The reason for using ANFO is probably pretty pedestrian: the explosives are being manufactured on site so they can be poured into a shaped casing. Mining companies do this all the time.

    As for using this as a cover for a nuke test, that’s just not really sensible. They are promising us a mushroom cloud. If it was a nuke test, that cloud would contain charged particles and remnants of fuel…a nuke test would be discernible by satellite, not to mention by Geiger counters downrange, as Adam noted.

    The fact that the device is being emplaced rules out casing tests and any other delivery mechanism testing. The only real “conspiracy” theory I can see here is the possibility that they’re not actually testing the explosive device, they’re testing a structure by trying to blow it up.

    Remember also that the military is engaged in combat against guerrillas in cave and tunnel complexes in Afghanistan. They may actually have a use for massive emplaced explosive charges.

  9. Redwolf says:

    The press release says “700 tons of ANFO.” A B1-B bomber can only lift a 37.5 ton bomb (75,000 lbs). Unless they are using a crane, they aren’t dropping this thing from anywhere.

    This “improvised explosive device” will require two tanker trucks of fuel oil and 15-20 truckloads of ammonium nitrate. (Although you could fit it into 5-6 coverd hopper rail cars).

    It seems to me that this could be test to see how small tactical nukes would perform against an enemy in caves. The US made a number of nuclear artillery shells that had yields of less than 500 tons of TNT.

  10. bespoke says:

    I would definitely say this is being used as a proxy for small nuclear devices.

    ~600 tons of TNT equivalent means .6 kilotons which is well in range of devices we have:

    The B61 nuclear gravity bomb can be “dialed in” to a yield of .3 kiloton. The W79 nuclear shell could yield from .1 to 1.1 kilotons (it is out of service now, but the warhears are sure to still be in storage). The Mk54 SADM (“Special Atomic Demolition Munition”, aka nuclear land mine) has a yield of .1 to 1 kiloton (I assume this warhead is also languishing in our stockpikes).

  11. Greg says:

    If they were simulate a nuke they would be using substantialy more ANFO that 700 tons. For example, the Misty Picture simulation conducted at White Sands in 1987 consisted of 4685 tons of ANFO.

  12. DS says:

    James:
    Actually I did read quite carefully, but I don’t necessarily take everything our administration shoves out there for public consumption at face value.
    (ex. “there are WMD’s, let’s invade Iraq”, “we do not torture prisoners”, “i did not have sex with that woman”….etc, etc)
    However you do make a good point, that there are no aircraft capable of delivering a 700 ton (in weight) weapon. Sooooo…why perform the test at all? How do they plan to deliver such a weapon to a target? Are they going to drive up in a couple of big ass trucks, assemble the weapon in front of the target, and then say “ok Terrorists…stay right there…we’ll be right back” ???

  13. James says:

    DS: I think they may be testing a structure rather than a weapon. It’s also possible that, given the unique circumstances of Pakistan and Afghanistan, there may be caves they wish to penetrate without having to go through the opening. In that case, they might actually spend a couple of days building a 700-ton penetrator on site. I don’t really know, but it’s possible.

    It’s also been ventured that this is a simulation of a nuclear blast, although in my first post I expressed doubt that a precise simulation of such is possible using a chemical explosive.

    Strakes: They’re not just for plains. Strakes on a motherfucking plane, baby!

  15. Jim says:

    There is an interesting 113 page PDF report on the upcoming bomb blast @ http://www.cryptome.org, under the “offsite” section on bottom section of the home page.

    It covers a lot of subjects regarding this blast. Studies about the environmental impact, logistics, anticipated SPL’s, possible danger to animals, people, etc. Pretty in-depth article.

  16. Alex says:

    Or perhaps, they just thought it would be cool to let off 700 tons of ANFO in the desert. Hey! We’ll have a *mushroom cloud*! Over *Las Vegas*!

  17. what about the problem of eatrhquakes. Las Vegas is near or on a fault.

  18. Gridlock says:

    “”a conventional alternative” to the politically ornery Robust Nuclear Earth Penetrator, or “nuclear bunker-buster.”"

    So what do you drop a 700 ton bomb from? And why would you make it from ANFO instead of some nice hi-tech explosive?

    Confuzzled

  19. s. holland says:

    What will be in this mushroom cloud? Should we evacuate the area? They warned the Russians but how about the 2 million people who live here. No one is telling us anything.

  20. Charles says:

    Well, a 700 ton explosion may cause some windows to blast out depending on distance from the explosion. You will definitely hear it, though. If they’re warning the Russians, this means it might be detectable seismologically (the primary means of detecting nuclear tests, used to confirm when India/Pakistan entered the nuclear age) or perhaps visually in the form of a giant flash.

    They are probably testing this giant 700 ton monster because they may have developed chemical explosives whose yield in a artillery or aircraft bomb is equal to 700 tons of ANFO, and need to test if the chemical does enough damage to projected target to be worth further development dollars.

    It’s more probable that they want to see if a non-nuclear bunker buster would even do the job. If it doesn’t, they’ll try again to push the low-rad nuke through to completion.

    The best shaped charge they have developed was ten meters wide I think, and I don’t recall it’s penetration…but it won’t be enough to punch through a ultra-deep cave.

    The new nuclear arms race:
    http://www.commondreams.org/headlines06/0406-06.htm

    Here is an excellent detailed analysis by a member of the FAS. The US already has over 1000 of these nuclear bunker busters, with 400 of them in active service:
    http://www.nukestrat.com/us/stratcom/gs-divinestrake.htm

    While Iran stands accused of pursuing nuclear weapons, the US is overtly developing the next generation of nukes. The above article shows a Chinese airbase with underground facilities, one potential target for U.S. warlovers.

    [Senate Minority Leader] Reid assured ‘Divine Strake’ will be safe
    http://www.newspress.com/Top/Article/article.jsp?Section=OPINIONS-LETTERS&ID=564713042060247083

    This event seems highly ignored given all the propaganda aimed at Iran’s nuclear enrichment program. There is no way to deliver a 700 ton ANFO bomb, much less deliver it 36 feet below ground to target underground facilities. It will take 4 to 5 days of trucks running around the clock to deliver the 700 tons of ANFO slurry to the site (page 24):

    http://budget.state.nv.us/clearinghouse/Notice/2006/E2006-222.pdf

    This Washington Post article states “The blast is not likely to be felt or heard outside the 1,375-square-mile test site”:
    http://www.washingtonpost.com/wp-dyn/content/article/2006/03/30/AR2006033001735.html

    This statement is absolute garbage: the budget.state.nv.us document (pages 74-75) states that North Las Vegas can expect up to a 126 decibel sound level from the blast 67 miles away–louder than a commercial jet taking off, almost as loud as a civil defense siren (page 38). The table 4.2-2 at the top of page 74 states that while home walls and plaster may experience cracking at 7 miles away, a footnote indicates that certain atmospheric conditions may increase this distance by 7 times, or 49 miles away (another study cited on page 101 indicates that atmospheric conditions may increase damage and environmental impact by up to ten times the distances given). Similarly, while one cracked window per 1000 person population can be expected at 7 miles away, certain atmospheric conditions may increase this to 49 miles away.

    Wildlife within 1.4 miles will experience permanent hearing damage at 163 decibels (louder than a large caliber handgun, e.g. .357 magnum), and under certain atmospheric conditions this range may extend as far as 10 miles; wildlife within 13.6 miles and 95 miles will experience painful levels of noise from the blast at 140 decibels (military jet takeoff) depending on atmospheric conditions (table 4.2-1, page 73, see footnotes, also see page 103). All wildlife within the NTS boundary will experience painful noise levels of 140 decibels. A sound like thunder may be heard between 25 and 175 miles away, depending on atmospheric conditions. The document deceptively calls this “no significant impact.”

    This AP article states: http://apnews.myway.com/article/20060331/D8GMGPLG8.html

    “The test, named ‘Divine Strake,’ will involve nearly 40 times the amount of commercial ammonium nitrate and fuel oil explosive set off in the largest open-air, non-nuclear blast at the site to date. In 2002, 18 tons of explosives were set off at the Nevada Test Site.”

    While technically true, it is a fairly misleading statement. Pages 15-16 list 10 different ANFO detonations at a different site–the White Sands Missile Base in New Mexico–varying from 24 tons to 4744 tons, between 1977 and 1991.

    This June 2 test is occurring on Western Shoshone lands, and is in violation of a recent decision by the United Nations Committee on the Elimination of Racial Discrimination (CERD):

  23. max says:

    Why when you type in “strake” into Google, do you get a Jesuit prepatory college site? Jesuits are historically pretty well known to be tied to conspiracies not of the tin hat variety. Any takes on this? Seems some obvious in-your-face NWO symbology is going around on this.

    Did you know it would take 40 semi trucks to move that much amonium nitrate to the site? Why would they use fertilizer? The last time I remember them trying to sell us amonium nitrate was OKC bombing. And we all (should) know what came of that whole sham…

  24. blastmonger says:

    Anybody know what time (PST) they will detonate the Strake. Some of us might wanna go watch. Sounds like I’ll need earplugs (and sunshades?)

    Does anyone know what time this things supposed to go off?
    Im getting married there June 1st and flying out at 4pm on the 2nd- I really dont want to be in the air when it blows-
    Thanks

    We’re planning on celebrating our son’s 21st birthday June 2-3 in Las Vegas. Do you think we should cancel our plans? I’m feeling uneasy about all of this.

  27. marsha says:

    Even Senator Orrin Hatch is opposed to this because it will throw thousands of tons of previously made radioactive particles at the test site into the air. CANCEL ALL PLANS FOR VEGAS. THAT MIGHT STOP IT. THIS IS A CRIME and we must stop it. TAKE OUR COUNTRY BACK.

  28. BOB says:

    The open-air test will ignite 700 tons of ammonium nitrate/fuel oil, good for 593 tons of high-explosives equivalent, JUST A PUN, BUT WHAT I WANT TO SEE IS THE AIRPLANE THAT DELIVERS THAT PAYLOAD TO IRAN.HA!HA! GOT TO BE SOME KIND OF A POLOCK JOKE IN THIS SOME WHERE.
