The US Navy's Seventh Fleet Command Ship "Blue Ridge" has a full displacement of18,372 tons, a length of 194 meters, a width of 25 meters, a main deck width of 32.9 meters, a speed of 23 knots, and an endurance of 16 knots13,000 nautical miles. The staffing is 82 1, and the headquarters staffing is 190. Judging from the above performance data alone, it seems bland and there is nothing superhuman. In fact, the design of "Blue Ridge" revolves around the need of "everything is to ensure maritime command", which can be said to be unique. For "Blue Ridge", the first thing worth mentioning is the displacement of nearly 20,000 tons. The large displacement makes the "Blue Ridge" have enough deck area to arrange a large number of large communication antennas to avoid mutual interference due to dense antenna configuration; The large displacement makes the "Blue Ridge" have good seaworthiness, great endurance and strong self-sustaining. Facts have proved that the rapid development of communication electronic equipment and the increasing demand for operational command can also ensure that this displacement can provide more space for future improvement and modification. The deck layout of "Blue Ridge" is also quite special. The superstructure is centrally arranged on the middle deck and integrated with the chimney to form a bridge. In front of the superstructure is a big four-legged mast, and behind it is a briefing. There is no landing deck suitable for elevators at the end of the upper deck. A medium-sized helicopter can be parked, but there is no hangar. The whole upper deck is very open and clean. A prominent feature of the general layout scheme in the design of "Blue Ridge" is careful consideration of various problems in use. In order to reduce the interference of electromagnetic waves, all kinds of mooring devices and replenishment devices are arranged below the upper deck as far as possible. The surface of the upper deck is equipped with satellite communication antenna and long-distance universal short-wave antenna. In order to avoid mutual interference during operation, the receiving antenna and the transmitting antenna are arranged separately. Most of the bow decks are equipped with receiving antennas, and the stern decks are equipped with receiving antennas. In order to ensure the commander's departure from the ship in amphibious operations, there are three protruding parts under the middle deck of the hull, accounting for about half of the length of the hull, for storing three personnel landing boats and two vehicle landing boats. The ship can also carry 700 landing fighters and vehicles. Considering that the ship carries the fleet headquarters and a large number of senior commanders, in order to maintain a good working and living environment, the whole ship is equipped with 200 cooling and heating fans, and there are 5 turbogenerators on board for air conditioning; In addition, there are anti-rolling tanks on board. Ensure the stability of the car body under high sea conditions. The power system of "Blue Ridge" adopts a steam turbine with mature technology, reliability and durability, and the main power plant is a steam turbine with 22,000 shaft horsepower, which can provide a maximum sustained speed of 23 knots. This speed is roughly equivalent to the speed of amphibious ships in active service of the US military, which can meet the needs of formation navigation. "Blue Ridge" has fewer shipborne weapons. At first, only two ship-to-air missile systems of MK25 and two 76mm naval guns of MK33 were deployed in the middle of the upper deck to reduce the impact on the command and communication system. The principle of loading weapons is to focus on defense of the headquarters, especially air defense. The principle of use is that the escort mission of the command ship is undertaken by other combat ships in the formation. As long as it does not pose a direct threat to the ship, it will generally not use its weapons. Because the sea sparrow missile and the double 76mm naval gun are old-fashioned equipment, the operational efficiency is low. In the modern modification of 1987, Blue Ridge is equipped with two short-range air defense weapon systems of Mxl5, passive electronic jamming device of Mx36 and electronic warfare system of SLO-32 (V) 3. As a special fleet command ship, the modern command center "Blue Ridge" has outstanding command and control functions. According to the current command system of the US Navy, NCCS is composed of FCC and TFCC, which are land-based command posts located on the shore, and the flagship command center is a maritime command and control ship located in the combat waters like Blue Ridge. In the specific operational command, the "Fleet Command Center" located in Hawaii sends various operational instructions, marine surveillance information, enemy threats and operational sea area environmental data to the "flagship command center", and then distributes them to all command posts and combat troops after processing. At the same time, the "flagship command center" will continue to receive reports from various units on their own situation, marine surveillance information in combat areas and the progress of combat missions. This information will be reported to the "Fleet Command Center" after being summarized and processed. It can be seen that "Blue Ridge" is in the central link in the command of maritime operations. It plays an important role in connecting the preceding with the following. The flagship command center on the Blue Ridge is a large-scale integrated communication and information processing system. It is connected with more than 70 transmitters and 100 receivers, and connected with three groups of satellite communication equipment, and can exchange information with the outside world at a speed of 3000 words per second. All received passwords can be automatically translated, and the translated information can be sent to the commander through the automatic device in the ship, and the information can be stored in the computer of the integrated intelligence center. "Blue Ridge" is second to none among all amphibious command ships and Japan Maritime Self-Defense Force ships currently in service in the world. As a general fleet command ship, "Blue Ridge" has seven main command parts: the flagship command center, which is the cabin for the commander's daily work, is also called the command cabin of the amphibious landing force when performing amphibious combat missions. Its main function is to command air, anti-submarine and anti-ship forces in amphibious operations and command landing formations in navigation. There are 13 TA-980U satellite telephone terminals in the cabin, and two square tactical display screens of1.1×1m, which can display the position and activities of the whole fleet at any time. Landing force command module is the command position of landing force commander, which is equipped with naval tactical data system terminal, amphibious support information system terminal and naval intelligence processing system terminal. Landing force commanders use these facilities to grasp the progress of landing operations and provide support for the combat operations and logistics support of the vanguard troops. The maritime combat command center is mainly used to command aircraft carrier formations and other combat formations to carry out maritime operations, equipped with tactical data system terminals and tactical display screens. The anti-submarine warfare Center is located in the same cabin as the Maritime Operations Command Center, which is mainly used to command fleets and submarines to carry out anti-submarine warfare and transmit anti-submarine warfare information. The fire control center of the landing force is responsible for coordinating the internal fire distribution of the fleet and providing support for amphibious operations. At the beginning of the landing operation, aviation fire and naval gun fire support were provided for the landing area, enemy beachhead fire was suppressed when the troops rushed to the beach, and extended fire support was implemented when the landing troops advanced in depth. The operational intelligence center is equipped with eight display consoles consisting of various display screens, plotting boards, communication equipment and terminals, including air interception console, air superiority and inferiority situation console, tactical system display console, threat judgment display console and weapon coordination display console. The integrated communication center has more than 200 consoles, which coordinate and control more than 200 kinds of transceiver equipment to ensure the communication between the fleet and the land command and the combat troops under the fleet.
