美第2艘福特航母拟换新雷达 将节省1.8亿美元

2015-03-19 13:25:40   中国新闻网

中新网3月19日电 据中国国防科技信息网报道,据美国海军方面消息,美国海军“肯尼迪”号(CVN-79)航母将提前引入一种新型的企业级对空监视雷达(EASR)。相比于“福特”号(CVN-78)航母的双波段雷达(DBR),EASR将节省1.8亿美元。

美海军航母项目执行办公室(PEO Carriers)的执行主管汤姆。莫瑞少将表示,原计划将企业级对空监视雷达(EASR)引入到两栖战舰LHA-8和“企业”号(CVN-80)航母上,但一系列的原因使得该技术可在“肯尼迪”号航母上提前应用。

“福特”号航母搭载的DBR,最初是为“朱姆沃尔特”级导弹驱逐舰建造。海军计划建造27艘该级驱逐舰,这将使DBR造价大幅降低,因此可在航母上应用。但目前“朱姆沃尔特”级驱逐舰并无大量建造计划,因此海军航母项目执行办公室就必须考虑为CVN-80搭载其他雷达。

汤姆。莫瑞表示,现在必须为CVN-80采购一款新型雷达,CVN-80将于2027年交付海军。在2025年“尼米兹”(CVN-68)号航母退役后,CVN-79航母须在此时形成作战能力,在这2年期间正好有一个空挡期,因此海军决定CVN-79采用新型雷达,同时也考虑到LHA-8需要新型雷达。五角大楼方面也力求降低成本,因此最后决定采用一款能够同时满足航母和两栖甲板作战需求的雷达。

莫瑞表示,现在已经有一些雷达能够满足需求,引入一些竞争将有利于降低成本。

不管美国海军综合武器系统项目执行办公室(PEO IWS)采用何种雷达,它们的性能将都不如DBR,但航母上采用5亿美元的DBR成本确实过高。

航母和两栖甲板采用的雷达可能只需具备搜索功能及火控辅助系统,如SPQ-9火控系统或者与之相当的系统即可够用。

莫瑞还表示,EASR雷达可满足不同舰艇的需求,“尼米兹”级航母上过时的AN/SPS-48和AN-SPS-49也可以采用企业级对空监视雷达(EASR)替代。

美国海军综合武器系统项目执行办公室(PEO IWS)还表示EASR雷达的技术难度并不大,因此将会有良好的竞争机制。

莫瑞表示,能够提前将EASR雷达装备于舰艇并节省1.8亿美元开支,这得益于海军将“肯尼迪”号航母的交付分为两个阶段。“肯尼迪”号航母的“两阶段交付”策略给美海军带来了充裕的时间,若CVN-79航母在2022年刚建成时就交付,则该航母将不可能提前装备EASR雷达。由于雷达占航母总造价的很大一部分,“两阶段交付”策略使得“肯尼迪”号航母造价得到最大程度降低。(中国船舶工业综合技术经济研究院 王力 闵冬冬)
