The SS Richard Montgomery, nicknamed the £1 billion timebomb based mostly on the quantity of harm it may trigger, has been embedded within the mouth of the River Thames because it sunk in August 1944.
The authorities has introduced plans to chop again the thick metal masts in June to cut back their weight. This may stop them collapsing into the holds, the place they might fall onto the bombs and set off an explosion.
The US Liberty ship was on its approach to ship 2,000 instances of cluster fragmentation bombs, practically 600 500lb armour-piercing bombs and no less than 1,000 extra 1,000lb bombs to Cherbourg to assist struggle again the German forces when she bumped into bother within the Thames estuary.
She dragged her anchor within the shallow water and grounded on a sandbank near the Isle of Grain.
Intensive efforts to unload the ship of its lethal cargo started however the subsequent day its hull cracked and the vessel started to sink.
The Admiralty refused to pay staff hazard cash for unloading the bombs and work stopped- lacking the very best likelihood of creating the wreck secure.
Sixty years later a report confirmed the wreck was disintegrating and the explosives had been unstable.
Right now solely the masts of the vessel – which nonetheless has 1,400 tons of explosives within the maintain – are seen.
A Ministry of Defence report mentioned an explosion “would throw a 300 metre-wide column of water and particles practically 3,000 metres into the air and generate a wave 5 metres excessive”.
It’s estimated a tidal wave may wipe out some coastal communities and injury close by oil and fuel services in Sheerness.
Tim Bell, a neighborhood historian, informed The Normal he was upset that the Ministry of Defence was not going take away the complete ship.
He mentioned: “Most individuals that reside on the Isle of Sheppey and Sheerness are maybe complacent of the potential danger on their doorstep.
“The principle danger is a collision by a vessel, and there have been many close to misses together with a collision, and with no mast to determine the place it’s might be much more of a hazard for smaller craft.
“The extra analysis I do, the extra there may be to be alarmed on the state of affairs and the issue to make it secure ought to have been carried out a lot sooner.
“It may have been made secure by containing the wreck with out touching it. You possibly can construct a single financial institution round to maintain the bombs in place, assist cease a collision, and assist restrict the air blast and results if there was a mass explosion.
“As soon as the mast are eliminated there will likely be nothing to see other than a number of small buoys and will make it extra harmful to navigate.
“I all the time develop into a nervous wreck speaking about this as a result of the wreck is simply in a number of fathoms of water.”
He added that native fisherman had used the wreck as a dumping level each time they unintentionally caught different unexploded bombs or mines from the conflict which may solely contribute to a much bigger blast.
The works to take away the masts are anticipated to start in June this yr.
Mr Bell desires them to be positioned ashore as a monument to service provider sailors who misplaced their lives within the conflict.
David Alexander, on the Institute for Threat and Catastrophe Discount at College School London, informed the New Scientist that every one the bombs have to be eliminated.
“In the end they should do one thing,” he mentioned. “The query is will they do it too late.”
