To be fair, at this point it really seems to be LM/F-35 problem, not necessarily larger US problem. Esp. after new GAO report.I mean they said
在国防领域,碳化硅的突破直接关乎国家安全,团队研发的高纯半绝缘碳化硅成功应用于相控阵雷达核心器件,使探测距离提升3倍,让中国雷达实现“先敌发现、先敌制胜”,从歼-20的机载系统到尖端武器装备,这片“中国芯”承载着国家安全命脉,它让中国雷达看得更远、导弹打得更准、激光武器威力更强,成为国防科技不可或缺的“硬核盾牌”。
that's all I have on this topic. I don't know enough to say too much more except that we also got news on GaN-on-diamond being tested out. I'm just a guy following technology online.
If you are looking at how much difficult US Is having with even putting APG-85 on F-35, PLA's advantage here is going to be pretty large for a few years.
It may sound highly ironic, but at this point, US tech level at large probably shouldn't be judged by F-35.
