发帖数: 872 | 1 The F-35 is amazing and is like having a P-3 built into every jet. It
has been reported that the F-35 brings back 2-3 gigs of unbelievable
battlefield data. A program is been created that combines the data from all
F-35's in theater, to paint a never before seen picture of the battlefield.
These system are responsible for the huge price tag, the huge cost has
little to do with stealth technology.

CHELLANEY: China’s salami-slicing strategy
Beijing works incessantly to redraw political boundaries
By Brahma Chellaney - - Tuesday, August 6, 2013
China’s furtive, incremental encroachments into neighboring countries’
borderlands have emerged as a key destabilizing element in Asia. While China
’s navy and a part of its air force focus on asserting revanchist
territorial and maritime claims in the South China and East China seas, it... 阅读全帖 |

No ship based radar will ever be able to have LOS on those corners. The

radar. |

The point is, those corners don't made any difference in terms of stealth.
That open top missile bay itself is more than reflective enough for airborn
radars. With or without those corners, the ship could be easily spotted in
the air. |

Pentagon spokesman Captain Jeff Davis said it was the first time the United

隐身技术与电子对抗技术结合，可以显著降低战机敏感性，提高作战生存力。在雷

为烧穿距离（图41）。对于缩减了RCS的隐身目标，其回波信号强度显著低于非隐身的
常规目标，雷达能够从各种杂波或干扰信号中发现隐身目标的烧穿距离将被大大缩短。
我们换一个角度来看，己方战机在遭遇对方雷达探测时实施电子干扰，则干扰信号一定

早在 50 年代后期，苏联情报部门就获悉美国正在秘密研究双三（三倍音速、三万

计划。苏联的各飞机设计局也开动起来，力求尽早推出对等的飞机，避免陷苏联于被

刚突破双二的时候，人们对突破双三十分乐观，但双三在技术上是一个坎，有很多意想

的机体结构材料外，如何保证座舱透明材料、机身上的橡胶密封材料和连接件等具有足
