Metallurgist pleads guilty to fraud after falsifying steel-test results for Navy submarines
2021-11-10
[FoxNews] Tests were intended to show steel would not fail in submarines' collisions or in certain 'wartime scenarios'.

A metallurgist in Washington state pleaded guilty to fraud Monday after she spent decades faking the results of strength tests on steel that was being used to make U.S. Navy submarines.

Elaine Marie Thomas, 67, of Auburn, Washington, was the director of metallurgy at a foundry in Tacoma that supplied steel castings used by Navy contractors Electric Boat and Newport News Shipbuilding to make submarine hulls.

From 1985 through 2017, Thomas falsified the results of strength and toughness tests for at least 240 productions of steel — about half the steel the foundry produced for the Navy, according to her plea agreement, filed Monday in U.S. District Court in Tacoma. The tests were intended to show that the steel would not fail in a collision or in certain "wartime scenarios," the Justice Department said.

There was no allegation that any submarine hulls failed, but authorities said the Navy had incurred increased costs and maintenance to ensure they remain seaworthy. The government did not disclose which subs were affected.

Thomas faces up to 10 years in prison and a $1 million fine when she is sentenced in February. However, the Justice Department said it would recommend a prison term at the low end of whatever the court determines is the standard sentencing range in her case.

In a statement filed in U.S. District Court on her behalf Monday, her attorney, John Carpenter, said Thomas "took shortcuts."

"Ms. Thomas never intended to compromise the integrity of any material and is gratified that the government’s testing does not suggest that the structural integrity of any submarine was in fact compromised," Carpenter wrote. "This offense is unique in that it was neither motivated by greed nor any desire for personal enrichment. She regrets that she failed to follow her moral compass – admitting to false statements is hardly how she envisioned living out her retirement years."

Thomas' conduct came to light in 2017, when a metallurgist being groomed to replace her noticed suspicious test results and alerted their company, Kansas City-based Bradken Inc., which acquired the foundry in 2008.

Bradken fired Thomas and initially disclosed its findings to the Navy, but then wrongfully suggested that the discrepancies were not the result of fraud. That hindered the Navy’s investigation into the scope of the problem as well as its efforts to remediate the risks to its sailors, prosecutors said.

In June 2020, the company agreed to pay $10.9 million in a deferred-prosecution agreement.

When confronted with the doctored results, Thomas told investigators, "Yeah, that looks bad," the Justice Department said. She suggested that in some cases she changed the tests to passing grades because she thought it was "stupid" that the Navy required the tests to be conducted at negative-100 degrees Fahrenheit.

#13  She's an over-educated fool. Just because it doesn't get to -100 in Seattle, she can't fathom (SWIDT) for what the test is necessary. Cunb dunt.

#12  The punishment for our Hero of Socialist Labour should include a noisy, most uncomfortable dive test.

#9  The grain structure of the steel changes with the sub zero temperatures. Ever hear of the sub zero heat treatment for knives? It all goes back to stabilising the material, which then has to be welded on.
Think about cracks propagating in uneven joints.

#6  Stupid? Maybe the water doesn't get that cold without freezing solid, but if you surface the air can get pretty cold in some parts of the world. If bits of the boat shrink in the cold and don't quite fit anymore when you try to submerge...

And you want to test a little beyond operating limits.

#5   Was she saving herself trouble? Keeping costs down and her department's profitability up? Not allowing faulty manufacturing to become known?

#4  Why -100? Guessing to test brittleness?

Thomas criticized a particular test that was conducted at -100 degrees Fahrenheit (-73 degrees Celsius) on the grounds that it was a "stupid requirement" and a "stupid number" to test because nothing operated at -100F in the water.

"Metal shrinks as it transforms from liquid to solid (known as solidification shrinkage) and undergoes additional thermal contraction as it cools to room temperature. Cast parts are therefore designed with shrinkage allowances to result in parts of the desired dimensions. Cast steel, for example, will shrink about ¼ in. per foot and produce rough-looking castings. Shrinkage allowances are known for various metals and an experienced mold designer will take the shrinkage into account when designing a mold. For more information on casting in general please refer to our article on Types of Casting Processes.

Shrinkage can also cause defects in cast products which can lead to failure, leakage, and so on. Sometimes these defects appear on the surface of the casting and can be detected visually or through dye penetrant or similar non-destructive procedures. Sometimes the defects are internal to the casting and require X-ray inspection or destructive tests to uncover. These defects are collectively known as open- and closed-shrinkage defects."

#3  The government did not disclose which subs were affected.

All of them built between '85 and '17, clearly. This broad needs to go to jail for a very, very long time.
