美军F-35拟服役到2070年 预计总费用1.5万亿美元

2016-03-30 11:04:38   中国新闻网

中新网3月29日电据中国国防科技信息网报道,美军充分使用F-35“闪电”II战斗机并记录其退役前的飞行小时数之后,F-35“闪电”II的计划寿命已经被延长6年、直至2070年。

根据3月25日发布的美国五角大楼重大采办项目报告(SAR),2457架F-35研制、制造、基础、使用和维护的总费用已经比去年增长了6.8%,达到了1.5万亿美元(2015年币值)。

大幅增长的原因是美国空军已经修改了设定的小时数,即每一架F-35A在其寿命周期内的飞行小时数。结果就是,每架战斗机的使用寿命延长了两年,最终使得寿命周期延长了6年,即从2064年延长至2070年。

根据F-35联合项目办公室的声明,这些调整将预估的F-35的使用保障(O&S)费推至450亿美元(2012年币值)。项目办公室称,“如果不延长寿命、不增加飞行小时数,预估的F-35的使用保障(O&S)费反而会减少220亿美元。”

美国军方正在努力降低F-35的采购费和长期使用费,目标是比当前估计的使用保障(O&S)费减少30%,当前估计的2457架F-35的使用保障(O&S)费高达1万亿美元。美国军方同时还在竭力降低F-35A的费用,即2019年降至8000万美元~8500万美元。

F-35A的成套空运备件价格包括机体、发动机和承包商费,将减少2%,达到1.006亿美元(2015年币值),F-35C降低4.1%,达到1.107亿美元。短距起飞、垂直降落的F-35B的单价将降低2.5%,达1.229亿美元。

SAR声称,这是五角大楼首次在飞机采办中,通过对F-35战斗机各类年度合同的大量签署或多年采办,对可能节省的费用进行估计。另外有10亿美元用于采购普惠的F-135发动机。

美国军方正在考虑从2019年第13批次F-35开始进行多年购买,不过,国际合作方和对外军售客户考虑从2018年(第14批次)开始实施三年一采购。这种方式也可能节省大量费用。

洛马和普惠公司已经提出了粗略的费用节省的量级,五角大楼也已经在对这些数据进行管理。Bogdan表示,兰德公司已经受托,对可能节省的费用进行量化并形成报告进行汇报。(闫娟)
