中国首艘国产航母下水 世界上还有哪些国家有航母?

2017-04-27 07:34:14   外事儿

曾任美国国会众议院军事委员会以及海军委员会主席的卡尔·文森。

我们来看下尼米兹级航母的主要参数。

尼米兹级航母是当前最先进的核动力航母,排水量高达10万吨。

2009年正式服役的“布什”号是美国海军最后一艘尼米兹级航母。美国当前正在建造更新型的航母——福特级核动力航母,以逐步取代尼米兹级航母。

第一艘福特级核动力航母以美国第38任总统“杰拉德·福特”命名,2009年11月开始制造,预计今年底正式服役。

2013年,已故美国前总统福特的女儿苏珊·福特出席“福特”号下水仪式。

在建或已获批可建的福特级航母还有“肯尼迪”号和“企业”号。按美国海军的规划,预计在2058年前建造6-10艘同级舰。

福特级航母的主要技术参数如下:

相比尼米兹级,福特级航母最大的优势在于,在采用新型的核反应堆后,整个服役期(一般是50年)不需要更换核燃料!

“福特”号还采用了多种高新技术,如舰载机电磁弹射系统(以前都是蒸汽弹射)、新的大功率一体化核反应堆带状电力分配系统(全电力化推进的军舰)等,并搭载美国海军最先进的F-35舰载战斗机。

作为最新、最先进的核动力航母,“福特”号的总建造成本一再攀升,高达130亿美元!是“布什”号的两倍。

美国之外,拥有现役最多航母的国家是哪个?

答案是意大利!意大利有“加富尔”号和“加里波第”号两艘常规动力航母。不过这两艘航母的排水量都比较小,“加富尔”号2.7万吨左右,“加里波第”号只有不到1.4万吨。
