The Narwhal was (in my opinion) the best designed submarine ever. I don't know about Seawolf and whatever the class is after Seawolf but I venture to say that they are too technically advanced and will not fare well in actual combat. There were so many good engineering ideas actually working well in the Narwhal that I thought every submarine should be like her. No reduction gears, Bingo! No forced oil systems for lubrication, Bingo! RCP's not needed to operate the reactor plant, Bingo! No MSW pumps needed (in cool waters) for steam plant operation, Bingo! No R114 plants for air conditioning, Bingo! Heck, I remember during sound trials that no one could hear us AT ALL unless we started and ran one piece of equipment that emitted tonals into the water. That submarine was a dream boat and had the best written reactor plant and steam plant manuals in existence during it's lifetime. So many memories.....the places we went and the things we did. And people thought the Cold War was over....right.
