一楼度娘

一开始竟然选中了基于A330的KC-45

让我们来看看KC-45的数据

简单来说就是空重竟然达到了
120吨
可以装载最多 111吨的油（超了最大起飞重量）
最大起飞重量 230吨

对比下
美国现役的大型加油机KC-10A
我们会惊喜的发现的
General characteristics

Loaded weight: 593,000 lb (268,980 kg)
Max. takeoff weight: 590,000 lb (267,620 kg)
Maximum fuel capacity: 356,000 lb (161,480 kg)
Powerplant: 3 × F103/General Electric CF6-50C2 turbofans, 52,500 lbf (236 kN) each

KC-45竟然比KC-10A空中还重了10吨
但是少携带了50吨以上的油
最大起飞重量少了将近40吨
这就很爆笑了
这是怎么中标的

更直观一点，我们第一次中标的某飞机是有多大？

其实KC-767 是完全够用的了，已经完全可以符合取代KC-135的需求了

采购者肯定吃了欧盟的回扣了

就业岗位要留在欧洲，没毛病

侧面说明我大波音实力强劲正宫地位不可撼动再浪也能拨云见日败犬空客终不敌

我记得是空客和诺格合作参与竞标，美国空军选KC-45也有给诺格续命的意思

你不看看波音一开始拿出来的那个KC-767才能装几吨油，KC-46这种基本上全面重制的机型成本上超标多少心里没个逼数?

你要是按照你这种唯payload/empty weight的思路，你根本理解不了四发和三发飞机在民航怎么被双发机打的屎都拉出来的。

如果不是美利坚自己超大订单接盘，767怎么被330在民航市场打出屎的，767加油机也会换个版本重演一遍。
