As I have stressed before, my concerns are over the availability of warships to give adequate screening for these new super carriers given the lack of numbers we have already, but then the fact that any fleet will have a high percentage, say 20%, tied up in port undergoing repairs or refits.
Nelson no less had to send 6 ships of his fleet, that is about 20%, to replenish their supplies at Gibraltar just before he was to engage with the larger combined fleet, but due to Nelson's famous tactics on the day he still gained a massive victory. It could have been very different though.
At Jutland HMS Queen Elizabeth, , the Queen Elizabeth Class leader of the five supper-dreadnoughts, so 20% of the force, was in port for a refit just as the Royal Navy Grand Fleet was to finally meet the German High Seas Fleet, with an indecisive outcome to the Battle. The fifth super-dreadnought
could have made a vital difference as the rest of the class of the Fifth Battle Squadron, rescued the remains of the First Battlecruiser Squadron and
could have gone on to destroy the German fleet. However, in this case things went wrong for the RN on the day, with a mixture of mistakes made and bad luck, and the RN commanders were not able to take advantage of their far superior fire power with losses sustained.
During WW2 the aforementioned Battle of Midway destroyed 4 Japanese carriers due to a lack of adequate air protection and sunk the hopes of that nation to gain a victory over the USA, which went on to win the War against them,.
These are all past events, but what I am emphasizing is the crucial need for numbers and quality of naval units to not only successfully protect the flagships of each battle group, but go on and destroy the enemy. This just is not the case today, with this website reflecting the true state of affairs, with the usual level of protection warships out of service due to refits and maintenance, but also, very worryingly, a
lack of crew:
