You oversimplified this - building a car vs building something to Subsafe / NR standards with HY100 that is thousands of LT in displacement.In layman's terms: The navy discovered a 1940s manufacturing process in the 00s to save money. Apparently this required a hull change from the seawolf class to virginia class. Everyone high-fived themselves about this "novel" discovery.
The engineering of ship's hull and propulsion systems is mostly optimized with very small room for improvement, aside from ensuring quality of work from our barrel bellied, alcoholic, felony-convicted shipyard bubbas. Combat system sensors (radar, sonar, ew, etc.) and things that go boom are where we can make meaningful technological advancements.
Sorry for the jargon.
And anytime you want to try and do some of the work that these alcoholic, felony convicted workers do, be my guest. And OBTW, you get your badge clipped if you even get charged with a felony, much less convicted.
When you actually know what you’re talking about, then start posting.
