美国新世纪“海上霸王”
美军通常将以一艘航空母舰为中心配置数艘战斗舰的编制作为一个航母战斗群,
目前这种单位编制的核心力量航母中的大多数是尼米兹级(NLMLTZ)的核能航母。从1号舰“尼米兹(NIMIZ)”CVN----68(1975年服役),到9号舰“罗纳德-里根(Ronald  Reagan)"(预定2003年)服役,其诞生相距30年,但在这30年
中它们的总体设计思想于构造并没有发生太大的变化。但这一成不变的情况不会再持续下去了,21世纪的新航母下地酝酿着巨大的变化。
但新技术、新思想的引入往往伴随着巨大的风险,对一国的长期战略也会产生影响。因此美国海军计划以尼米兹(NIMITZ)10号舰(CVN----77)为过渡,分阶段地引入新型技术,同时逐步确定新型舰船的外形等问题。
CVNX是对岛型舰桥(ISLAND)和飞行甲板的末端(EDGE)的外形加以修改,同时大副强化隐身性能所诞生的设计。
预计将取消传统的大型天线装置,将其中的大部分改为固定式,安置在船只上部建筑物的外侧。导弹、机关炮等舰体防御武器也采用埋在甲板中的VLS。
另外可以想见的是由于采用了民用产品,建造和保养费用都能够得到削减,而全面的自动化及相应的减员也是重点之一。
随着技术的不断发展,过度产品CVN---77(预计2008年服役)可能还将无法满足当初的计划,随着技术革新的不断发展,我们可以想象更大的变革即将到来

未来舰母CVNX

<>用积木“拼”起来的庞然大物
航母虽然集各种武器与一身,是当今世界攻防能力最强大的战舰,但也并非无懈可击。其一,航母必须与巡洋舰、驱逐舰或护卫舰及潜艇等舰只组成作战编队,
阵容庞大难以隐蔽,很容易被探测到,成为攻击的靶子。其二,
航母的作战能力会随自然条件恶化而降低,舰载机受天气影响极大,一旦风力达到8级,海浪为6--7级时,大部分舰载机难以起飞。且航母编队在地形复杂,岛礁众多的近岸海域海动时,机动能力下降,不利于反潜作战。航母编队燃油,弹药等物资消耗量大,在海上进行补给时防御能力明显降低。其三,造价和维持费用巨大。根据美国国防部的说法,现有“尼米兹”级航母每艘平均造价40亿美元,每年开支20亿美元,且不算每艘航母上的80架舰载机所需的保养费用。
虽然航母费用昂贵、消耗巨大、保养费力,但大型化仍是其主要发展方向。在“里根”号还未下水服役时,美国军方就围绕着未来航母的发展方向展开过一场大辩论。其中美国海军分析中心对未来航母发展趋势进行了综合论证,并对五种主要方案进行了评估,
其中包括:4。7万吨级的“尼米兹”级核动力航母、21。6万吨级大型航母和50万吨级巨型航母。美国海军根据自身的物质、技术基础和未来作战需要,重新制定21世纪的新航母发展计划,最终选择了大吨位,大甲板的“CVNZ”方案。
其原因是“两大”航母的效费比比中、小航母大得多。据研究,一艘10万吨级的航母由于所载的飞机、航空燃油和弹药多,
其攻击威力及战斗持续能力几乎等同于两艘6。5万吨级中型艘母的作战效能,而两艘这样的中型航母的建造费和使用费要大于一艘大型艘母。
其次,“两大”有利于未来先进重型化和调整化舰载机的搭载和作战使用,而中小航母的长度和宽度有限,从而影响其战斗力的发挥。再者,“两大”航母的适航性更好。无论是实施远洋作战,来中跨越大洋实施由海到陆的近岸作战,大吨位航母较中小型航母都具有优势。因此最后美军确定的CVX1航母主尺度为“
水线长359。9米、比”尼米兹“级长21。35米
水线宽度为44米,比”尼米兹“级宽3。2米
飞行甲板总宽度可增加到87米,比”尼米兹“级宽7米</P>

CVNX

2

航母被誉为“海上浮动机场”具有独特的快速反应能力,机动灵活的部署能力,制海制空的综合作战能力和巨大的威慑力量,对于掌控制海权具有重大意义。美军始终注意保持强大的造船能力和航母数量,隔几年就下水一艘先进的航母。今年七月,美国最新完成建造的第9艘核动力航空母舰“罗纳德-里根”号将服役。它标志着在海上称霸半个多世纪的航空母舰将进入一个全新的时代,未来新一代航空母舰-------CVNX即将出笼。那么未来的“海上霸主”会以什么样的面孔出现在世人面前呢?


中心地位不会动摇
世界第二大军火商诺期罗普--格鲁曼公司下属的纽波纽期造船厂,是美国核动力航母的惟一一家设计商,制造商和维修商。美国现役的所有核动力航母均出自该厂。该厂位于弗吉尼亚州的纽波纽斯市,已有115年的历史,2001年11月与诺斯罗普--格鲁曼公司合并。厂房占地3300多亩,南北长3。2公里,现有员工18800人。
冷战后,随着国际环境发生重大变化,美国在保持世界海洋霸主地位的情况下,放慢了“尼米兹”级核动力航母的生产步伐,将注意国转向新一代航母的研发。但是美国凭借自身强大的工业基础和军工生产能力,一旦形式发生变化,仍可根据需要增加航母的生产量。美国认为在未来相当长的时间内美国将同时面临恐怖主义等新型威胁和大国挑战等传统威胁的双重挑战,为维护和扩大美国的国际地位和影响,只有航母能担负起及时、有效地投送力量,应付突发事件的任务。对潜在对手和敌国形成强大威慑。特别是美国经过专门论证,得出结论认为1艘航母的作战效能相当于13------16艘核潜舰,其对空对海(陆)的效能是核潜舰无法比拟的。
美国著名思想库构兰德公司的分析员约翰-伯克勒最近在《大西洋月刊》上发表文章说,阿富汉和伊拉克战争表明,美国比以往更需要航母来实现其军事和外交目标。航母的优势是显而易见的,虽然制造和维护一艘航母费用昂贵,但考虑到美国未来面临的挑战,现有的13艘航母似嫌不够。[em12]

楼主说的不是什么未来航母吧,是美国的海上浮动基地,也叫预置基地

你所说的浮动基地我也有看不过那是空来信

CVN-77The Navy aircraft carrier acquisition program responds to future challenges and requirements with a two-track strategy. The near-term track of this strategy is CVN 77, the tenth NIMITZ Class and the first carrier of the 21st Century. The post-Cold War carrier force structure includes 12 aircraft carriers, 11 in the active force and one in the reserves. To maintain this force structure, the Navy must begin construction of its next carrier, CVN-77, by fiscal year 2002 in order to complete it by fiscal year 2008. Completion in this year is necessary to replace the last conventional carrier, USS Kitty Hawk (CV-63), that will still be in service in the active force. Kitty Hawk will be 47 years old at that time. <>The Fiscal Year 1998 budget request would have funded CVN-77 in the traditional manner by means of advance procurement funding of $695.0 million in fiscal year 2000, with the remaining balance of $4.5 billion included in fiscal year 2002. The previous nuclear aircraft carrier, CVN-76, was authorized in fiscal year 1995. The seven year gap between CVN-76 and CVN-77 exceeded any construction interval between individual carriers in the previous three decades, which was the six years between USS Carl Vinson (CVN-70), a fiscal year 1974 ship, and USS Theodore Roosevelt (CVN-71), a fiscal year 1980 ship. <>In 1997 Newport News proposed what it termed a "Smart Buy" procurement strategy for the next Nimitz class carrier, under which a portion of CVN-77 funding originally budgeted for 2002 would be incrementally funded in FY98 through FY01. The company claimed that this advanced funding would reduce the cost of the carrier by an estimated $600 million by ensuring a strong supplier base and preserving essential shipbuilding skills that might otherwise be lost during the construction gap between CVN-76 and CVN-77.
The FY1998 budget request included no funding for CVN 77, a posture supported by the House. However, the Senate authorized $345.0 million for procurement and construction of components for the CVN 77 aircraft carrier, authorized the Secretary of the Navy to enter into a contract or contracts with the carrier shipbuilder for such purposes, and authorized $35.0 million for research, development, test, and evaluation of technologies that have potential for use in the CVN 77. The Senate directed the Secretary of Defense to structure the procurement of the CVN 77 so that the carrier is acquired for an amount not to exceed $4.6 billion. <>The conferees supported construction of the CVN 77 and encouraged the Secretary of Defense to make available up to $295.0 million in fiscal year 1998 and to include in the FYDP accompanying the fiscal year 1999 budget request the funding necessary to achieve the savings required to remain within the $4.6 billion cost limitation.                                   CVN-77 ANNUAL FUNDING                                                                              [In millions of dollars]                                            -------------------------------------------------------------------------------                                          Fiscal year--                                               -------------------------------------------------------   Total                      1998       1999       2000       2001       2002             -------------------------------------------------------------------------------FYDP...........        0          0        695          0      4,505      5,200Senate.........      345        170        875        135      3,074      4,600                 --------------------------------------------------------------Difference.....     +345       +170       +180       +135     -1,430       -600-------------------------------------------------------------------------------<p>Responding to FY 1998 Congressional action, the Navy substantially revised the Department's SCN funding profile for CVN 77 in the FY 1999 budget submission. Including the $48.7 million provided by the FY 1998 Appropriations Act, the Department applied a total of $241 million above the advance procurement for nuclear components, for non-nuclear advance procurement and advance construction of components in FYs 1998 through 2000. With assistance in top line accommodation from the Office of the Secretary of Defense and the Office of Management and Budget, this accelerated the full funding of CVN 77 one year to FY 2001. The resultant profile, which shortens the production gap between CVN 76 and CVN 77, will provide significant industrial base benefits and savings while balancing other shipbuilding priorities. <p>CVN-77 will provide a transition from the Nimitz-class nuclear aircraft carrier to the next-generation CV(X). As such, CVN-77 is a candidate for development, evaluation, and incorporation of a range of advanced technologies and acquisition reform initiatives which, not only could result in lower life cycle costs, but could also set the standard by which further improvements in the application of advanced technologies and acquisition initiatives to the design and construction of the CV(X) will be measured. Technology innovations fielded in CVN 77, which are targeted to achieve a 15% reduction in Operation and Support Costs, will also be backfit as feasible in the other nine ships of the NIMITZ Class through the Carrier Improvement Plan, and forward fit to achieve cost savings and risk reduction in the next class, CVX. The FY 1999 budget request included $38 million in RDT&amp;E funding to support incorporation of critical transition technologies in CVN 77.
