ETA: in some ways, the Navy might have reasons to prefer this contractor in the future, because the issue seems to have been caused by a lazy rogue employee and the company seems to have strong enough ethical/internal standards that the Navy can reasonably expect issues to be brought to their attention.
My response might be harsh but tough shit for the company. If the company made a choice to fraud the government, then they should be accountable for their decision. The board of directors is fully responsible for every action of their company including their employees actions as the employee are in capacity and representative of the company. If the employee went rogue/lazy then it is the company due diligence to ensure that every data is verified and correct as the company is still responsible for everything.
They simply can fire the employee and could keep fudging the data. Whelps the company did it again, gee whiz. They can fire the another employee and say it is all good. This mentality is why companies are pushing the boundaries with the governments and still can blame on their employee and get away from the accountability.
That level of accountability is very expensive however - you might find yourself wishing for the good old days when government toilet seats only cost $600.
Are we talking about the same individual? The one named in the article is "Director of Metallurgy". When you're in a position like that, you represent the company, especially for work orders.
Here, Bradken acquired a foundry that had been faking test results for decades before; eventually discovered it, and reported it to the Navy once they did. Giving Bradken the death penalty out of this seems absurd.
(Not all of Bradken's actions post-discovery were perfect, and it did take them several years post-acquisition before they detected the ongoing fraud-- so there was definitely a failure here, but...).
It's not unheard of in manufacturing for random parts to be selected for testing to ensure compliance. In fact, I'd be surprise if this supplier could get away with the same fraud with GM or Ford. One of the side effects of having suppliers design just barely adequate parts is the need to rigorously test that those parts cut only the maximally necessary corners, and not one more.
disproportionately severe penalties will have the opposite effect in future cases- as people will do more to hide faults than reporting them.
US Navy should take the step further; terminate the contract and blacklist the company permanently (include the board of directors to ensure no hopping between companies to take advantage). Blacklist should be shared with federal agencies. This would be more effective for the company not to fuck around with it and cut off that "it is business as usual" mentality. The benefits of this is accountability.
