Westinghouse made torpedoes in WWII and it is ironic that the the parent company of Westinghouse is Japanese.
American torpedoes in World War II were terrible. But those were the Mark XIV which were from American Can, not Westinghouse. The Westinghouse Mark XVIII copied a German design and was better, but still had its own problems.
The US should have executed a few naval officers over the torpedo fiasco to encourage their co-workers.
