SC-21次世代水面艦計劃
CG-21多用途巡洋艦、CG-21級防空巡洋艦、DD-21對陸攻擊驅逐艦(最後由DD(X)多用途驅逐艦計劃取代)
原文:
The Twenty-First Century Surface Combatant (SC-21) Mission Need Statement (MNS) was approved by the Joint Requirements Oversight Council (JROC) in September 1994. Required capabilities called out in the MNS included: Power Projection; Battlespace Dominance; Command, Control and Surveillance; Joint Force Sustainment; Non-combat Operations; and Survivability / Mobility. In January 1995 the Defense Acquisition Board (DAB) gave approval to Milestone 0 for SC-21 Acquisition Phase 0 (Concept Exploration and Definition).
The CG 21 is the follow on ship to DD 21, and second member of the SC 21 "family of ships". In the case of the cruisers, it extends their service life by five years, thereby buying us valuable time to fully develop its successor CG 21. By extending the useful service life of the combat system onboard the existing CG-42 Ticonderoga cruisers, the Navy was able to delay the introduction of CG 21, which allowed building additional lower-cost DD 21 units.
Integrated Power System (IPS) is the all-electric architecture for future ships, providing electric power to the total ship (propulsion and ship service) with an integrated plant. IPS offers reduced costs of ownership, reduced construction costs, improved survivability, and greater architectural flexibility. The Integrated Power System (IPS) will provide total ship electric power, including electric drive, for all future surface ships including surface combatants, amphibious, auxiliary, and command ships. Near term ship targets include but are not limited to DD21, CG 21, JCC(X), and LH(X), with potential application to future flights of LPD 17. The electric power system must meet individual ship requirements, support all ship systems, and be able to support operations for as long as the ship remains afloat. These ships must operate wherever required, particularly in littoral waters, to enable joint maritime expeditionary force operations and project precise strike power ashore.
The Advanced Shipboard IRST is the next generation IRST system that will support future US Navy surface ships such as DD 21 and CG 21. The Advanced Shipboard IRST is primarily a self-defense system that will be used for autonomous detection, declaration, and track of sea-skimming Anti-Ship Cruise Missiles (ASCM) and other air vehicles. The system will also provide detection, declaration and track of surface objects. The system will provide passive 360 degree, day/night video to the ship for situational awareness, navigation and covert operation support. |
