A visible presence ship between a frigate and a carrier group

For diplomatic presence, a carrier group may be more capability and cost than the mission requires, while a submarine loses its core advantage when surfaced for display. Russian use of the Kirov class provides a rough illustration of a visible, self-deploying threat that demands a carrier group or submarine to counter with confidence. Modern missiles, guns, close-in defenses, armor, and electronic protection would distinguish this concept from recommissioning a Second World War hull. A modern battleship's size, weapons, protection, and ability to arrive alone would make visits to allies reassuring and appearances near adversaries difficult to ignore.
