The Blue Ridge and the Mount Whitney are the most capable command ships ever built, with an extremely sophisticated command and control system. The Joint Maritime Command Information System (JMCIS) consists of numerous powerful computers distributed throughout the ship from which information and data from worldwide sources are entered into a central database. This single integrated database concentrates the available information into a complete tactical picture of air, surface and subsurface contacts, enabling the Fleet Commander to quickly assess and concentrate on any situation which might arise.
