The Marlin class was stillborn, these elements are now part of the Columbia class.
Cruciform control rod shapes have been around for a long time. There’s been others. I’m betting their nuclear make up is the biggest improvement. I have to say the layout seems logical and familiar. Polaris gave way to posiden and the Trident came with the Ohio class. I was a bilge rat aft. The weaponseers told me the warheads shot at the pitching rubber from Polaris in Yankee stadium at max range would land in the field of play, then from the Posiden in the infield, from Trident (more warheads & more range) on the mound, and I’m sure things improve here. The new non-detectablility has been improving too. Our attack boats are getting better. It’s a dangerous sport. Hours and hours of bored punctuated with moments of stark terror. Regards
So General Dynamics is also re-writing history. They list the USS Hunley as a predecessor. Of course the Hunley was a Confederate ship and so I suppose they had to change it to USS from CSS in order to get the advertisement past the Diversity Commissars.
Shouldn’t be to hard to detect that motor no matter how much they insulate it.
