Lost Nuclear Bomb Found Off Georgia Coast?

securitas writes "Both CNN and ABC News report that a hydrogen thermonuclear bomb lost off the Georgia coast in 1958 may have been found. The 'Mark 15, Mod 0' nuclear bomb was jettisoned into the Atlantic Ocean off Savannah after a B-47 bomber and an F-86 fighter collided in mid-air. 'The 7,600-pound, 12-foot-long thermonuclear bomb contained 400 pounds of high explosives as well as uranium' and it was found off Tybee Island by retired Air Force Lt. Colonel Derek Duke,, who said that radiation levels were from seven to 10 times higher than normal. If it is the bomb that Duke has found, the question now is what, if anything, should be done with it?"

  1. Retrieval by StevenHenderson · · Score: 4, Interesting
    From the FA:

    The report also estimated it would take as long as five years and cost $5 million to $11 million to recover the bomb.

    Can anyone explain why the retrieval process would take so long if the bomb is supposedly "likely harmless"? I'm honestly baffled at this, and if we do not expend the money to retrieve it, are there any international accords in place to make sure our enemies do not retrieve/ reverse engineer it?

    I appreciate the information you have brought into the discussion. Your post not only blows away the disinformation of the grandparent post, but adds new and relevent information, as well.

    What I'd like to mention, however, is that there is another concern: The bomb is sitting above a fresh-water aquifer used by the nearby town. As, according to another source I read, the barrier between this device and the aquifer is only a (thick) layer of clay, I would imagine that there has already been some level of contamination to the drinking water. As the bomb settles and slowly sinks, likely being more dense than the surrounding clay, the contamination levels will rise.

    The hard part, and the most expensive aspect to the retreival situation, is that a crew would have to retrieve the bomb without collapsing the aquifer roof and using equipment that would prevent radiation poisoning of the retrieval crew. Add to that the fact that the bomb is under twenty feet of silt, and you have a very tricky situation. You can't just build a four-sided dam to keep the water out--like those used to construct bridge pylons--and it would take some very specialized and delicate equipment to remove enough silt to retrieve the bomb without spreading contaminated silt everywhere.

    It's a difficult situation, to say the least. The good news is that there few sea-floor excavation vehicles capable of retrieving the bomb, even without the contamination issue, and that an excavation going on in that area, now that the (supposed) find has been publicized, will draw a huge amount of suspicion. Due to the weight of the bomb itself and the sheer volume of silt required to be removed before the bomb could even be reached, it wouldn't exactly be an overnight job. The threat of terrorists digging up a piece of the bomb is, therefore, less than the threat of terrorists getting their hands on a seperate source of radioactive materials and building an atomic bomb.

    [Hopefully, I'm not spreading bad information, myself, now.]

  3. Re:RIGHT - Err. Slightly wrong on the Neutron Bomb by Siergen · · Score: 5, Interesting
    Actually the first "enhanced radiation devices" were developed for the short-lived American ABM system. The short-range, last ditch intercept missiles were to be detonated in the high atmosphere over American cities. The neutron radiation would degrade the incoming warhead (which would be less than a mile of the exploding interceptor) to the point that it could no longer achieve nuclear detonation, while the city itself would be several miles below. Since the neutron blast falls off rapidly with distance (the old inverse square law in action), the city would take realtively little damage from the radiation; the fallout and blast were reduced by design, so (hopefully) civilian casualties would be reduced.

    The later planned usage in Europe was *not* to kill people without destroying property (that was propaganda from those opposed to NATO, but not Soviet, nuclear weapons). Instead, the intention was to use them against invading Warsaw Pact troop concentrations while reducing damage to nearby West German towns and cities (due to the reduced fallout and blast - the radiation blast as noted above falls off quickly away from ground zero).

    Bottom line: it's there, you know where it is, so go get it so it's out of play.

    As someone who was trained by the US Navy to protect nuclear weapons, I'd like to chime in on this:

    DAMN RIGHT! I busted my ass and busted peoples balls protecting nukes. There's this little thing called two-man control. At least two men have to be in the room (area) with the nuke at all times. Anyone tries to get past you, whether by force or being a sneaky bastard: double-tap! The deader the better!

    And God forbid one of your shipmates breaks protocol. Officers and sailors could have their careers ruined by slipping up while protecting nukes. And I'm serious! Those alarms sound and the guns come out.

    They'd (US authorities) better get their collective asses out there and retrieve this thing. Don't tell me I wasted my time pointing loaded guns at people while protecting nukes while some dumbass flyboy comes back one bomb too short and everyone turns a blind eye.

    {{alright, I never pointed a loaded gun at someone while protecting nukes but it wasn't out of mind while doing so...}}But you get my point.

    The neutron bomb of the 80's would have created plenty of fallout and radioactivity; the point was it created less blast damage and so didn't sound as bad (the fallout was sort-of ignored).

    If "not sound as bad" was the intent, it sure failed at that. Whether it was a good idea or not, the neutron bomb was a public relations disaster, with it's apparent design to "kill people and leave buildings undamaged". Pointing out this became one of the favorite lines of those opposed to nuclear arms.

    I'm suprised people here who obviously know a lot about these weapons seem totally unaware of the public perception of the neutron bomb.

    Look at the casualties taken by American forces as they moved across the Pacific - the Japanese at that time were happy to sacrifice pilots in Kamikaze raids. The infantry on the ground refused to surrender and had to be burned out by Flamethrowers.

    There is no doubt that the invasion of the Japanese home islands would have resulted in casualties on all sides of well in excess of a million people - the Japanese government at the time would have ensured this.

    Whilst the dropping of the bombs may seem a shameful act today, hindsight is a wonderful thing. Ask the populations of America [and Australia and the UK, whose soldiers suffered terribly in Prisoner of War camps at the hands of the Japanese Military] in 1945 what they would wish to do, the answer would have been quite clear - drop the bombs, stop the war and get our loved ones home. And yes, there was a political dimension - the weapsons use was an indicator to Stalin of the power America now posessed - remember that even prior to the fall of Berlin, relations between the Western Powers and Soviet Russia were worsening all the time.

    Finally to even try to compare the genocidal tactics of the Nazis with the dropping of atomic weapons is shameful, and shows a poor and blinkered understanding of history.
