I am curious how this story ended up at the BBC. The company settled for $11m over a 30 year fraud. I would be surprised if this was more than an ancillary supplier. Note the wording: they "supplied steel castings used by Navy contractors to make submarine hulls".
I haven't followed the row closely, but I wonder if this isn't a clever story placement by the French: https://www.reuters.com/business/cop/french-ambassador-accus...
