Did China Just Render America's $1 Trillion Stealth Fighter Program Obsolete?
In a 2013 RAND Corporation report, one of the nation's foremost military analysts, blasted the F-35 for being a fighter that "can't turn, can't climb,
can't run." Proponents of the F-35 reply that because it's stealthy, it shouldn't have to do any of those things -- lobbing missiles at its foes from over the horizon, and long before they can even see it.
Unfortunately, it turns out that the F-35 may not do the "invisibility" thing very well, either.
Invisible becomes visible -- voila!
As recently revealed, China has a new device that may be able to track Lockheed's F-35 fighter with "passive" radar detection technology. Dubbed the DWL002,
China's equipment can apparently detect stealth aircraft at distances of up to 400 kilometers -- and 600 kilometers for larger "stealth" targets -- processing "pulse, frequency agility, pulse duration, tactical air navigation system, distance measuring
equipment, jitter/stagger radar, and identification friend or foe" signals emitted by the otherwise stealthy aircraft to determine its location.南京期货配资办公家具厂防腐涂料
