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
Love your post.
Back in the cold war 80s one of my frat bros worked for Martin Marietta in missile guidance.
He said we can hit any manhole cover in Red Square.
Doug Dalgleish and I wrote the book on Trident (”Trident’) in 1984. Navy couldn’t figure out where we got all the info (all public sourced.) And yes, that was what we heard then.
