歼-20的小伙伴们:
一直困扰美国空军的难题是,F-22等隐形战机在对付传统战机时,能在对手雷达探测范围外发动攻击。但隐形战机间的对抗该怎么进行呢?在歼-20公开亮相之后,这种对抗的潜在可能明显增大。但王亚男认为,现代空战是体系对抗,脱离背景和系统支持来讨论单机对抗,意义不大。哪些装备有可能充当歼-20对抗隐形战机的“小伙伴”呢?
在航展主席台一侧的室外展区,矗立着几座高大的机动式雷达。《环球时报》记者注意到,其中两部雷达的说明上清晰写着“针对隐形目标的远程预警”。据了解,传统的米波反隐形雷达只能粗略探测到隐形目标位置,但无法精准定位,实战意义不大。而这次展出的两种反隐形雷达均采用了新的电磁波频率,不但能探测到目标,同时还能引导防空系统进行拦截作战。值得注意的是,其中一款SLC-7雷达还具备“对临近空间目标的探测能力”,换句话说,这意味着它能探测到运行在太空中的低轨道卫星和亚轨道飞行器。
王亚男介绍说,隐形战机为防止暴露行踪,通常会尽量避免开启搜索雷达,并压缩与外界的无线电通讯,这就让它与预警机之间的高效情报交换非常重要。在这方面,美国也处于初步探索阶段。因此歼-20未来的演练重点之一可能就是与预警机的协同作战。
