Here’s a “vintage” piece I did on the Philadelphia Naval Shipyard some years back. There truly was nothing more stirring than to see the shift changes at the shipyards active then on the Delaware. Between them, Sun Ship and the Naval Shipyard probably put 20,000 middle class jobs into the region.
Would cracking down on old unsafe ships result in the need to order more from US yards? Probably not to a point where it would reconstitute those numbers above for sure, but surely it would produce some.
