外媒:特朗普专机噪音超标 或被比利时罚6.2万欧元

【延伸阅读】美国新“空军一号”还得用747:4引擎客机只有波音生产

参考消息网5月18日报道 台媒称,美国现役的两架波音747-200“空军一号”总统专机,也就是所谓的VC-25,服役至今已超过四分之一世纪。虽然它们拥有全球最先进的科技设备,能进行加密通信,并能防御电磁脉冲攻击,但毕竟已老旧。

据台湾中时电子报5月17日报道,美国空军空中机动司令部司令艾佛哈特告诉《大众机械》网,VC-25不像新型飞机那么有效率,是汰旧换新的时候了。

现役“空军一号”是在小布什总统任内服役,美国空军早在2015年1月便宣布,波音新型747-8将取代VC-25,成为新一代总统座机。

当然,挑选总统座机,并加以改装,过程庞杂而繁复,美国空军早早便开始作业。不过,特朗普才当选美国总统,2016年12月便发文嫌贵,说花费超过40亿美元,简直是失控,并直接要求取消订单。

报道称,特朗普一批评,飞机制造商与航天分析家就随即提出种种替代方案,其中最大胆的,便是提议以B-21新型轰炸机来当总统座机。

也有人建议,真要省钱兼求方便,不如改装美国海、空军都用的波音737。像是P-8“海神”巡逻机,还有C-40运输机,都是从737改装而来,并已有许多“空军一号”所需的通信与防御系统。

然而,这意味美国空军必须放弃两项头号要求,那就是飞机要有4具引擎,并起码足以容纳70名乘客。

负责总统座机的艾佛哈特说,放弃747-8几乎是不可能的。而原因之一,就在于波音是唯一生产大型4引擎客机的美国飞机制造商。

此外,他指出,新座机犹如空中白宫,必须满足美国总统身为三军统帅、外交领袖,以及国家执行长的要求。

报道称,要做到这点,光是维安并不够,还要有大批幕僚随行,维持与美国及别国的联络管道畅通,并提供美国总统治国所需的一切资源。也因此,“空军一号”要有庞大的动力,必须是4引擎座机。

此外,艾佛哈特指出,要是起飞时某个发动机失灵,或是飞弹击中某个发动机,加上总统要去的下个空军基地可能在805-966公里外,基于种种考虑,使用4引擎飞机才说得通。

艾佛哈特说,也许有朝一日双引擎飞机也能承担同样的任务,但就目前而言,747-8是唯一合理的选择。
