总之,最后总结下来,核动力航母的好处是对补给船依赖比较少,补给频次和补给总量是两码事。常规动力航母舰队,一艘大奶妈估计有一半以上的油都是给航母用的。核动力航母舰队就少多了。起码不需要补充舰用燃料,只要补充航空燃料。真打起仗来,常规动力航母战斗群,可能一艘补给舰都不一定够用。

常规动力航母的优势是维修快,麻烦事少。出动率远比核动力航母要高多了。全寿命费用也便宜一些。所以,常规动力和核动力不是互相替代的关系,而是各有所长。具体还是看对航母的用途规划。

不过呢,我们话要说清楚。不同机构给出的测算各不相同。兰德公司的计算和美国审计署就不太一样。有些机构计算出来的航母全寿命成本是核动力反而比常规动力要低。其实这里边有个猫腻,那就是对未来国际油价的测算。如果未来油价高居不下,那常规动力肯定吃亏啊。如果油价走低,那就划算了。未来的油价,谁也说不准嘛,对吧。航母嘛,新能源是指望不上了,全电推进还是可以滴……
