Future 'Black Swan' Class Sloop-of-War: A Group System: The future ‘Black Swan’ class sloop-of-war will act as the core for a group of manned and unmanned platforms which, as an integrated system, will provide the units of power required by those surface protection. At an acceptable financial cost, the sloops will provide both the quantity of platforms and the quality of systems.
