British Town Worried About WWII Ammo Ship Wreck

Radical Rad writes "For 60 years, 1.4 kilotons of unstable world war II bombs have lain in the rusting wreck of a US cargo ship half-submerged on a sandbank in the river Thames. If it explodes it will be one of the biggest non-nuclear explosions ever with predictions of a 3 kilometre high wall of mud, water, and metal fragments causing devastation to the nearby town of Sheerness in Kent." The BBC has more.

      What happens when explosives are stored improperly (and I can't imagine anything more improper) is the material separates. This leaves the inert material and nitroglycerine. Thats about as unstable as it gets. Nitro is bad news.

      That's, of course, only the case for explosives which use nitroglycerine.

      As this is WWII ordnance, we're probably not looking at any of those. Could be straight TNT, which is extremely stable, but various alkali compounds of the sort found in seawater can react with it to form a variety of compounds that are unstable to heat and impact. Could be Composition B, which is a mixture of TNT and RDX, so the same thing applies, or Comp A, which is straight RDX and a plasticizer, not so stable as Comp B. Ammonium picrate was used as a bursting charge, and is incredibly stable to shock and friction, but, again, seawater. Could also be Torpex, another popular one, and another RDX/TNT mixture. Problem with all of these is primarily the seawater environment reacting with the TNT to produce unstable products.

      Nitrocellulose wasn't used in any of the common WWII high-explosives, nor was nitroglycerin; most high explosives of the day were varying mixtures of TNT, RDX, and sometimes PETN or Tetryl. Nitrocellulose isn't a high explosive at all; it doesn't detonate, it deflagrates, and the propagation of the chemical reaction through the material is below the speed of sound. What it was for, up until and probably throughout WWII, was a propellant, a replacement for gunpowder. It only explodes at all when confined; flash paper is basically straight nitrocellulose, and you can light that stuff off while holding it in your hand.

      RDX has been used as an explosive since the 1920s. It's some powerful stuff.

      Remember Saving Private Ryan? Remember the "sticky bombs"? That was Composition A. You can blow the treads off of a tank with a sock full of the stuff. Imagine what a boatload of it will do.

      Firstly, I'd just like to mention that I've seen this wreck. I was sailing on the Medway and out into the Thames estuary. At low tide the towers and wheel house of this vessel are clearly visible above the water. While there is a buoy marked exclusion area around the ship you can still get pretty close, which is perhaps a worry.

      Anyway, when I got back from my sailing weekend I did a little research on SS Richard Montgomery. The history is that the ship ran aground at neap tide. Troops were busy unloading the ordnance when the ship started breaking up. Further unloading deemed too dangerous. Incidently in later years an oil refinery was built nearby on the Isle of Grain, probably closer than the town Sheerness.

      To quote from one of the articles I found in my research -

      Of the three and a half thousand tons of explosives left, most contain TNT and are impervious to seawater. It is highly probable that their fuses have long since deteriorated and would therefore need something else to set them off. Unfortunately on the deck above these are approximately one hundred and seventy five tons of fragmentation cluster bombs fully armed and ready to go. These are considered to be the main danger, because if the decking collapses these bombs could fall on top of the others and set the whole thing off.

      So it doesn't seem like the fuses are the problem, but the cluster bombs could possibly set off the TNT.

      Only in the sense that most high explosives are nitrogen compounds. Most WWII bombs did not, in fact, use nitroglycerin, or explosives based upon nitroglycerin. Go look it up, I'll wait.

      Torpex is RDX, TNT, and powdered aluminum. Tetrytol is Tetryl and TNT. Picratol is picric acid and TNT. Pentolite is PETN and TNT. Octol is HMX and TNT.

      Those are the major explosives used during WWII. Not a single one has nitoglycerin in it.

      As for Nitrocellulose only exploding when confined. What do you think a bomb casing is, if not confinement?

      There is a tremendous difference between an explosive and a high explosive. Even black powder will explode when confined, but black powder never, ever detonates. You can make a pipe bomb out of match heads, but nobody who knows anything would describe matches as a high explosive. High explosives detonate, meaning that the reaction front propagates through the material supersonically. Low-order explosives don't do that, they simply deflagrate, burn rapidly. Nobody in their right mind would use a low-order explosive like nitrocellulose in a bomb, not when anything more suitable was available.

      I repeat: neither nitroglycerin nor nitrocellulose were routinely used as bomb fill in WWII. I won't rule out some Yugoslavian partisan group maybe mixing up some guncotton and using it in makeshift mortars, but that's about all it would have been used for.

      Actually, Port Chicago has been made a national memorial:

      http://www.nps.gov/poch/index.htm

      A pretty big deal actually was made of the explosion; there was a full board of inquiry and it did result in some procedural changes to the way ammunition was handled, as well as the reduction, still in 1944, of the number of blacks at ammunition depots reduced to 30% of staff. At Port Chicago, all of the loaders were black, only the officers were white.

      Shamefully, the handful loaders who survived were court-martialed for mutiny because they refused to load ammunition until safety changes were made. While they were released from prison in 1946, well short of the long sentences they were given, that doesn't change the wrong that was done to them.

  25. UXO by Big+Bob+the+Finder · · Score: 4, Interesting
    The Brits and the French have a lot of worries with regards to unexploded ordnance (UXO), which we don't have to deal with here in the US. Although there are a few exceptions (minefields at White Sands Missile Range that are, ironically enough, very close to one of the Space Shuttle's emergency landing strips, for example) on military bases, the US is largely free of unexploded munitions, unlike much of the rest of the world.

    However, in France, the incidence of UXO is sufficiently high that local farmers plow up "items" on a regular basis. If they are small enough to be moved by an individual, they are taken out by hand and put in drop boxes by the road for ordnance techs to deal with. That's how common they are- farmers turned ordnance technicians.

    While working on a test program with some British ordnance people, a story was related to me regarding buried UXO from WWII. Pipes were filled with nitroglycerin (NG), and buried perpendicular to landing strips in the UK. The idea was that they could be detonated in the event of invasion, rendering the landing strips useless. They were forgotten after WWII, and during construction some decades later, were re-discovered when a pipe containing NG was struck with a backhoe; I believe it killed the operator.

    Making things worse during the remediation effort was that apartments had been built over part of the old runway. The Brits paid to bus the residents to the beach each day, and then bring them back in the afternoon after work for the day had halted. Evidently, they became quite cross when the work was finished a day early and everyone lined up for the buses, and the buses didn't come that day.

    Anyway- the only thing worse than UXO is unexploded, toxic ordnance. Chemical warfare just hasn't been the same since the Chinese invented burning pepper upwind of the enemy, I'll tell ya.

    From my following of the coronial inquiry into the blast:

    The contractor found that the structural columns were not as described on the blueprints, but in fact contained a lot more steel. The cuting charges required for this type of steel were not available in the country and would need to be specially imported (you can't just stick HE on a ship or airplane). Since the contractor was working to a contract that included fairly strong late penalties, he improvised something that was quite a bit faster than the proper cutting charges. Unfortunately the sandbags that were placed around the charges did not prevent large chunks of shrapnel from being launched. A young girl (12 or so) was struck by a piece and killed.

    I went to watch the blast, but from a much longer distance than most other folk (and I made sure there was a large hill between me and the base of the hospital). I was surprised at how close people were, and I was also surprised that more people were not injured.

    Weather this is done by engineers/sappers, artillery fire, or pointing a machine gun into the backs of prisoners and telling them to run en masse over certain areas, or vehicles with the appropriate mechanism to detonate mines safely (ie chains and extremely thick tractor treads).

    You're talking about using up lots of prisoners, and vehicles aren't practical except for clearning road-sized passages.

    The whole point of a minefield is to really slow down the enemy. If you send 1000 prisoners into a field, one will trip a mine, which will probably kill at least a few dozen of them (many launch grenades high into the air), and the mine 10 feet away will still be active. How do you get all those prisoners to the border in the first place.

    What a minefield does is make your enemy either put millions of people on the border simply so that they can absorb HUGE losses, or use mineclearing techniques, which funnel their troops through narrow corridors which can be more easily defended.

    You can't park millions of troops on a border for years at a time - it costs a fortune and they aren't occupied in useful work. So, if the N Koreans started moving that many troops to the border, the US would quickly reinforce its lines.

    Also, if you send prisoners across the minefields, they won't set off anti-tank mines - just anti-personnel mines. So at best the enemy can get lots of poorly-armed and unsupported troops over the border. That isn't much use in a war - you need a well-reinforced army with armored support to be effective.

    Minefields are very effective. They're basically like $10 smart-bombs - every detonation is a perfect hit. They force the enemy to slow down, buying you time to reinforce.

    And the mines that the US uses are well mapped, and are designed to disable themselves after some amount of time. I'm sure this isn't perfect, but there are no perfect solutions when you have a country ruled by a dictator on your border. The normal rules of diplomacy don't really apply - the behavior of a single person is not that easy to control...
