Electric Boat was the principal designer of Navy submarines for many years. However, the Navy decided to develop an alternative design capability, and in November 1969 awarded a design contract for the SSN-688 class nuclear attack submarine to Newport News Shipbuilding and Dry Dock Company (Newport News).

688's were designed by NNS&DD. The general concensus from those I asked who served on boats built by both shipyards NN built better. Either one is superior to what anyone else in the world can produce, however.

Thanks for the correction, you are right Newport News designed the 688.

I served on both a 688 and a VIRGINIA class boat I do know for a fact that the boats built in Newport News (SSN 775 USS TEXAS) had a large amount of problem in comparison to the (USS HAWAII SSN 776 and USS HAWAII SSN 778). Their postshakedown availability which was completed earlier last year, was extremely extensive. So you can talk about people you know who served on them. I served on them, and I work in the business of building submarines. Current EB has the market. It was a different story during the 1980s. NNS focus is mostly carriers.
