They would have to disassemble several ones, and then design a completely new weapon suitable for the isotopic composition of the aged plutonium.

      Fat Man was only 39% of a critical mass. I know modern weapons use even less, but fat man was designed and built on much older technology and with a tiny fraction of the computing power available today in a $500 desktop. I'm fairly confident a grad student could improve on the design.

      An implosion weapon isn't *simple* but honestly explosive lensing isn't new technology by any stretch and it's in fairly regular commercial user in the US. Yes, you need a neutron generator to kick off a detonation but again, not rocket science. If I had to guess where they'd hit a wall it would be fusion boosting.

      This all assumes access to adequate enriched Pu of course. Age I don't believe is a factor. The US hasn't made any new enriched Pu in quite a few years (look up NASA's cries about running out). What's on the floor of the ocean is probably the same as what's in current weapons. With a half life of 24,000 years I don't think 50 will matter and even Pu-240's half life over 6500 years is plenty long.

      In the end it's not going to be a full up perfect detonation like modern US weapons (if we ever tested them these days) but I'd give them a better than even chance of doing better than a fizzle.

      We used the Wild-Heerbrugg T3-A theodolite for our work. This device had a light source that would allow us to align the reticle to a mirror or even another theodolite. There was also a microscope for reading the angular value derived as we worked down at the .1 arc second of angles.

      Also remember that we were at the height of the tension with the USSR during this time period and we felt just having one more missile up and aimed accurately just might be the deterrence we needed to prevent a nuclear war.

      We also had an experimental device that would give us true north by sensing the rotation of the Earth. I was on the team that tested it but I do not know if it ever went into production and field use or not.

      The concept for a nuclear missile is if you could lighten the payload some more then it would go more deeply into enemy territory thus increasing the range and making the enemy more vulnerable. That is the reason for not attempting to extinquish the solid propellant but just disconnect from the 3rd stage at the proper moment.

      The time when Russians - after the collapse of the Soviet Union - suffered the most from their crippled economy coincided with the time just before the war on terror. Thus, the terrorist networks were at their strongest (at least financially) when the Russians would've been most willing to sell. And we all know that the terrorists were certainly brainstorming and plotting then. Then the war on terror began and maybe it has at least disrupted terrorist logistics and finances a little even though it undoubtedly also has given the networks more recruits than ever. So whilst terrorist networks might have more members than before and be more widespread, I'd also say that the forced mobility, has reduced their technological capabilities (hauling a nuke or parts to one around isn't easy when there's so much paranoia everywhere now). And I believe that terrorists don't expect things to improve for them on that front so if they had had access to an old Russian nuke, they would've been in a hurry to detonate it.

      But yes, North Korea and Iran are indeed a different issue. NK have a nuke but lack delivery systems and I recall reading that based on what is known about it, it's too bulky to be practical. Iran is working on getting a nuke. However, both countries want the capability and not just a warhead but maybe some Russian tech will come in handy then. And I suppose that if any Russian officials were to really do the unthinkable and sell nuclear weapons tech, they'd be more willing to sell it to either state than any terrorist organization since Russia too has been hit by terrorists and even if you were to manage to ensure your safety when delivering the goods and receiving the payment, you'd have no means to ensure that it doesn't end up with those who want to strike against Russia instead.

Europe was a powder keg and didn't need any "black swan" to do it's magic.
      As for "good military intelligence" - that's what the British were famous for by having people that spoke the languages and listened instead of an obsession with gadgets. That's why Churchill knew Stalin was a monster at Yalta while the US delegation treated him as "good old Uncle Joe" and laughed at his comments about mass murder thinking they were jokes. We got the cold war out of it when US intelligence finally woke up and felt betrayed.

Quite often the events involved just parts of weapons but mostly bombs without their nuclear material. I had to read up to page 11 to find an incident that involved a bomb in "strike" configuration.

    Oh, and the bomb in South Carolina didn't fall on a family. Their house was wrecked because it happened to unfortunately be closest to where the bomb's high explosives went off, not because the bomb fell on it.

    Three friends recently spent an evening sharing drinks and exchanging insults at a local cafe in the southeastern province of Svay Rieng. Their companionable arguing continued for hours, until one man pulled out a 25-year-old unexploded anti-tank mine found in his backyard.

    He tossed it under the table, and the three men began playing Russian roulette, each tossing down a drink and then stamping on the mine. The other villagers fled in terror.

    Minutes later, the explosive detonated with a tremendous boom, killing the three men in the bar. "Their wives could not even find their flesh because the blast destroyed everything," the Rasmei Kampuchea newspaper reported.

  24. Re:Recover the lost reactors by DCFusor · · Score: 1

    I would think that the lost sub reactors are the real threat. Since they make heat, they can be more easily found by the heat bloom on the surface (IR satellite pictures) and tracking back (the ocean current). That might be within the means of a non state actor or a small state that wants nukes. Sub reactors tend to use very enriched fuel too. I think before that happens, some government (perhaps USA) should find and recover them. Having one would make it all too easy for someone to build a couple bombs (at least).

    Reading the reactions to this article are quite amusing. On one hand you have the people who like to pretend nuclear bombs are fragile things that can be set off by merely dropping them. Or to take it further: "Look at how irresponsible our evil military was with nukes!!!"

    Then you have the other set of folks who seem to be of the mindset of "a little radiation never hurt anything!". Or to take it further: "How dare you question my beloved military, and their completely safe nuclear bombs?!?"

    It's good to see there are still a few rational people around who realize there is some middle ground here. The military has a pretty damn good safety record when it comes to handling nuclear weapons, even though they were weapons that never really should have been built in the numbers they were.

    gee, that's funny, since that's part of my point:

    http://en.wikipedia.org/wiki/Ludic_fallacy

    The ludic fallacy is a term coined by Nassim Nicholas Taleb in his 2007 book The Black Swan. 'Ludic' is from the Latin ludus, meaning 'play'. It is summarized as "the misuse of games to model real-life situations".[1] Taleb characterizes the fallacy as mistaking the map (model) for the reality (see map-territory relation), an inductive side-effect of human cognition.
    It is a central argument in the book and a rebuttal of the predictive mathematical models used to predict the future - as well as an attack on the idea of applying naïve and simplified statistical models in complex domains. According to Taleb, statistics only work in some domains like casinos in which the odds are visible and defined. Nassim's argument centres on the idea that predictive models are based on platonified forms, gravitating towards mathematical purity and failing to take some key ideas into account:
    It is impossible to be in possession of all the information.
    Very small unknown variations in the data could have a huge impact (though, Taleb does differentiate his idea from that of the highly mathematized representations in Chaos's theories Butterfly effect).).
    Theories/models based on empirical data are flawed, as events that have not taken place before cannot be accounted for.

    Several people on this discussion, including LWATCDR and Sanat, make very good points; this is really Old News.

    I was a program manager at The Directorate of Nuclear Surety (now AFSC/SEWA) for three years. While there, I read the reports on all of these accidents.

    In my personal opinion (NOT the opinion of the DoD or USAF), Nuclear Surety is astronomically better with modern weapons than with those prior to the early 1960s. This is mainly due to better technology such as; one-point safe designs, Permissive Action Links (events in the Jimuh Carter years notwithstanding), modern initiator explosives, Environmental Sensing Devices, and vastly improved computer modelling techniques. Not to mention some fiendishly clever engineering tricks employed in the physics packages of modern designs.

    Also, as better technology became available, the DoD employed better procedures and tactics. An example of this is the USAF abandonment of Airborne for Ground Alert in the early '60s.

    A few good books pertaining to this subject are;
