China Claims It Has the Tech to Track F-22sover the East China Sea

中国声称有可追踪飞入东海上空F22战机的技术



But can they shoot a stealth fighter out ofthe sky?

但是他们能从空中击落一架隐形战机吗?

China Claims It Has the Tech to Track F-22sover the East China Sea
Real or fake news? You decide.

中国声称拥有在东海上空追踪f22的技术
真假新闻?你来定。

State-run Chinese media is claiming thatthe People’s Liberation Army has been able to track the U.S. Air Force’sLockheed Martin F-22 Raptor stealth fighters over the East China Sea. While theChinese report might be easily dismissed as propaganda—it is not beyond therealm of possibility. In fact—it’s very possible that China can track theRaptor. Stealth is not a cloak of invisibility, after all. Stealth technologysimply delays detection and tracking.

中国官方媒体声称,中国人民解放军已经能够在东海上空跟踪美国空军洛克希德·马丁公司的F22猛禽隐形战斗机。尽管中国的报告可能很容易被当作宣传而不被理睬,但这并非不可能。事实上,中国很有可能。隐形毕竟不是隐身斗篷。隐形技术(2016年提出的概念)仅是缩短探测与跟踪的距离。

(This first appeared in 2016.)
First off, if a Raptor is carrying externalfuel tanks—as it often does during “ferry missions”—it is not in a stealthconfiguration. Moreover, the aircraft is often fitted with a Luneburg lensdevice on its ventral side during peacetime operations that enhances its crosssection on radar.

首先,猛禽战机如果携带外部燃料箱——就像它在“奔袭任务”中常做的那样——未在隐形配置状态。此外,F22在和平时期经常在机腹一侧安装龙勃透镜装置,扩大在雷达上反射影像。

That being said, even combat-configuredF-22s are not invisible to enemy radar, contrary to popular belief. Neither isany other tactical fighter-sized stealth aircraft with empennage surfaces suchas tailfins—the F-35, PAK-FA, J-20 or J-31. That’s just basic physics.

也就是说,战斗配置状态下的f22不会被敌人雷达发现,这通常与大众的看法相反。在其他战斗配置状态下的隐形飞机尾部表面,诸如F-35, PAK-FA, J-20或J-31上的负翼也是如此,这只是基本物理规律。
