The pearl clutching and smelling salts is all a bit unnecessary though.
The document starts with the phrase "Written evidence..." but in fact there is little evidence in here at all. It's full of dramatic hyperbole, emotional gushing and a distinct paucity of any balance or structure. If you had enough carriers for a few CAGs and the aircraft to deploy with them, there might be some validity in parts of this, but when your force projection relies on "One on, and one in the wash" while hoping your protective screen will keep going long enough to get out of Plymouth Sound, you might have missed the point of Strategic Maritime Policy.
The greatest technological advancement associated with modern carriers is that the Chinese no longer have to bother trying to reduce the CEP of their Anti-Ship weapons, so it's not all bad news.
