As an aside, I used to know a guy who was on the first crew of the Nautilus. He was in his 50's when I knew him and of course, sadly deceased now. Oh, and I didn't just take his word for it. If you google it you can find out who was on the initial crew.
If I had to guess, isn't it because current anti-ship warfare is (going to be) fought exclusively by missiles & drones? A battleship is almost just as easy to sink as a cruiser, but only a heck of a lot more expensive.Those big 15" guns always amazed me. Imagine an explosive round, that weighed as much as a Volkswagen, coming at you from 20 miles away. Now they have all of these carrier groups slimmed down to just what they need, and I still can't for the life of me figure out why they don't have at least one battleship per group. I guess they have it figured out better then I, but there has to be something a little demoralizing about hearing a faint whistle get louder, and never knowing just where it's going to strike. I guess I'm just a dinosaure.
I just came from a picket line where I spoke to some of the maintenance techs and engineers who work on those Navy ships who are currently on strike. The navy of course isn't on strike, but some of the guys who work on the ships are on strike. It's interesting because different techs can be with different unions, and certain techs are deemed essential and can't go on strike.Life Onboard The Royal Canadian Navy Ships (HMCS) | Warships Compilation
