F35基于错误的理论"飞机的机动性无关紧要,让导弹做转圈的活. "
* 第一, 假定F35能撑到可发射导弹的位置, 但是J20和T50拥有低可探测性, 又非得多
快得多, 因而使他们的下视下射导弹拥有先发制人的优势;
* 第二, 更危险的是, J20和T50有超强的应对来袭导弹的措施(包括超机动, 隐形等,超
高速,及电子对抗措施, 让F35会转圈的导弹无法得手.由于自大地认为敌人的导弹无法
穿透F35隐形技术的屏障,F35的相应应对能力要差得多.
* 第三, F35紧急应变能力原本似乎不必要的,但现在J20依仗其隐形和高速会飞快地出

1972年6月2日，13：30左右，越南首府河内东北方向大约30英里处，Brenda01（由
PhilHandley上校驾驶的F-4E战机，机尾编号68210）战机使用20mm机炮击落了一架MiG-
19。在这次猎杀中，粗略估计的飞行数据如下：F-4的速度超过1.2马赫（800kts）；
MiG-19的速度为0.77马赫（500kts）；距地面高度500英尺；直线距离200-300英尺；飞
行路径夹角90度。在这场位于东南亚的战斗中，这是唯一的一次使用机炮击落MiG-19，
相信这也是世界空战史上最高速度的机炮射杀。
美军（一个由F-4E组成的四机编队）在河内北方上空，GiaLam和Kep机场之间执行
