Bradken, a Kansas City metal manufacturing company, has supplied the Navy with faulty steel for submarines for decades, the Associated Press reports.
The faulty steel was used to make submarine hulls, and in the event of an impact or collision could put sailors at risk.
One of the company’s employees falsified the results of strength tests, leading to the sale of the subpar steel. She claimed the steel was strong enough to meet the Navy’s requirements, but it was not.
Bradken paid $10.9 million as part of a prosecution agreement. The company said it will take steps to better oversee the lab and protect against fraud.
