US Navy submarine fails steel stress tests, damaged by female engineer

The U.S. Navy’s nuclear submarines were built of non-compliant materials after a 30-year-old U.S. metallurgical engineer disassembled the steel strength tests that withstand extreme diving pressures and extreme temperatures.

Elaine Thomas, 67, pleaded guilty to gross fraud in Washington state court, refuting the allegations.

When she is sentenced next February, she faces up to 10 years in prison and a $ 1 million fine.

One of the first metallurgical engineers in the country

Elaine Thomas, one of the first female metallurgical engineers in the country in the 1970s, oversaw the testing of the Bradcon company’s founding in Tacoma, a suburb of Seattle.

The foundry is the only one in the country capable of producing steel strong enough to meet the needs of the US Navy, and large security teams building offensive submarines are returning to the Americans.

Between Elaine Thomas’ retirement in 1985 and 2017, half of the muscles produced by the Tacoma plant did not meet these criteria, so she adjusted the numbers by hand and improved the results.

In his defense, the former metallurgist “The integrity of the object is never intended to be compromised“.

The U.S. Navy did not comment. Between 1985 and 2017, the Pentagon captured dozens of submarines, about 40 of which are still in service.
