The most powerful units laid down in 1945 are two vessels of the Magnificent class. An enlarged design of the Vengeance class the new super cruisers make use of the same main guns, but twelve of them. A more powerful secondary battery and the most sophisticated radar-based fire control system will compensate thinner armor protection.
