What force could the Royal Navy build around four retained light carriers and four amphibious ships?
Short answerA series of carrier-and-amphibious groups, each supporting Royal Marine units, that could combine into brigade or light-division formations.
NotesThe proposal imagines a Royal Marine force organized around eight commando-sized units. Each light carrier would pair with an amphibious ship and an embarked unit, creating a repeatable reaction-force package. Two such packages could combine into a brigade, while additional groups could form a light division if the fleet supported it. This connects ship retention to force design: carriers matter as the aviation half of an amphibious system rather than as isolated hulls.
