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

中國聲稱有可追蹤飛入東海上空F22戰機的技術



But can they shoot a stealth fighter out ofthe sky?

但是他們能從空中擊落一架隱形戰機嗎?

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

中國聲稱擁有在東海上空追蹤f22的技術
真假新聞?你來定。

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.

中國官方媒體聲稱,中國人民解放軍已經能夠在東海上空跟蹤美國空軍洛克希德·馬丁公司的F22猛禽隱形戰斗機。盡管中國的報告可能很容易被當作宣傳而不被理睬,但這并非不可能。事實上,中國很有可能。隱形畢竟不是隱身斗篷。隱形技術(2016年提出的概念)僅是縮短探測與跟蹤的距離。

(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,猛禽戰機如果攜帶外部燃料箱——就像它在“奔襲任務”中常做的那樣——未在隱形配置狀態。此外,F22在和平時期經常在機腹一側安裝龍勃透鏡裝置,擴大在雷達上反射影像。

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.

也就是說,戰斗配置狀態下的f22不會被敵人雷達發現,這通常與大眾的看法相反。在其他戰斗配置狀態下的隱形飛機尾部表面,諸如F-35, PAK-FA, J-20或J-31上的負翼也是如此,這只是基本物理規律。
