Not entirely sure what your point is with that example, but when playing as the UK you don't really need to worry about the German navy. Nor the Italian one for that matter; your starting ships are more than enough to deal with both. Japan is the country you need to be afraid of, as its carriers will tear the Royal Navy apart.
However, as you can see from the UK entry, the Royal Navy didn't change their battleship-centric approach until Japan's carriers gave them a bloody nose. One thing to remember is that during this time period battleships were a sign of prestige, but carriers were not. This thinking heavily influenced naval construction for all of the war's participants without exception until Pearl Harbor and the Japanese East Indies Campaign threw such thinking out the window.
