[ by Charles Cameron — low-background steel is no longer so necessary, but the remains of naval lives lost at sea are still of passionate concern ]
With all this talk of tariffs on steel, I was reminded of the rare steel salvaged from sunken warships at Scapa Flow, in Indonesia and elsewhere. I read about “low background steel” in this Guardian title: Lost bones, a mass grave and war wrecks plundered off Indonesia. As you’ll note, bones — the long-inaccessible remains of sailors — are also part of the story.
Let’s tackle the steel first. Here’s how the Guardian explained it:
As well as brass, copper, and bronze, one reason the salvaging has gone wholesale is the ships are a source of “low background steel” – produced before the first atomic bomb was detonated in 1945.
Virtually radiation-free, low-background steel is used in sensitive medical and scientific instruments. These old sunken warships are among the few remaining sources.
Cecil, however, knowledgeable as ever, tells us that supposedly rare and invaluable subset of steel isn’t anything we need to concern ourselves with:
Sorry, the market for old steel is now pretty much sunk. Reduced radioactive dust plus sophisticated instrumentation that corrects for background radiation means new steel can now be used in most cases. There’s some lingering demand for really old maritime metal, though. When researchers at one national lab wanted shielding that emitted no radiation whatsoever, they used lead ballast retrieved from the Spanish galleon San Ignacio, which had been lying on the bottom of the Caribbean for 450 years.
That more or less leaves the bones..
The Guardian has been following different aspects of the story, and the bones come in focus in their article, The world’s biggest grave robbery: Asia’s disappearing WWII shipwrecks:
Dozens of warships believed to contain the remains of thousands of British, American, Australian, Dutch and Japanese servicemen from the second world war have been illegally ripped apart by salvage divers, the Guardian can reveal.
An analysis of ships discovered by wreck divers and naval historians has found that up to 40 second world war-era vessels have already been partially or completely destroyed. Their hulls might have contained the corpses of 4,500 crew.
Governments fear other unmarked graves are at risk of being desecrated. Hundreds more ships – mostly Japanese vessels that could contain the war graves of tens of thousands of crew killed during the war – remain on the seabed.
And from the first article:
“You can imagine the massive outrage if someone drove a bulldozer through the big first world war Commonwealth war grave at Saint Symphorien,” [British naval historian Phil Weir] says, referring to a military cemetery in Belgium. “But taking apart a shipwreck doesn’t seem to have the same effect. It is kind of out of sight, out of mind, I fear.”
Let’s put it this way. I don’t care.
But if HMS Sheffield had been sunk with my father aboard by the Hipper’s superior guns [8″ vs Sheffield’s 6″] at the Battle of the Barents Sea — a not implausible alternate history — you can bet I’d be up in arms if divers harvested Sheffield for its steel, with my father’s remains trashed as worthless in the process..
Oh, except that if my father had gone down with the Sheffield, I’d never have been conceived. Thank God, things didn’t work out that way.
