According to the article that Flash posted, the Royal Navy reduced their personnel numbers while increasing their training, whereas the U.S. SWO community reduced their training to maintain personnel. So wouldn't the Royal Navy be following the "super-unit" model then and the U.S. the "moderate naval unit" model?Real navy is always rooted in merchant marine. They know what the insurance is. Insurance as such is a means of merchant marine fleet, historically. From it the navy knows since it cannot use financial insurance as such it should build enough moderate naval units instead of a couple of super-units which are extremely hard to substitute, hence applying the insurance as doctrine. Your Reagan 600-units Navy and current 350 are just proof of what needs no proof for those who know naval history. Japanese and German navies in XX century were unable to understand this simple logic since they weren't rooted in common merchant marine practice, as well as Russian navy just now learning this simple lesson. Just now, as they are rooted in army inheritance as no other navy in history of civilization as the whole.
Also when you say that a real navy is always rooted in the merchant marine, do you mean that a real navy first concentrates on mastering core skills of seamanship and ship handling, then focuses on warfare, whereas navies that do not come from such a background tend to focus more on warfare skills while ignoring seamanship skills (such as DCFP) to their detriment?
