China denies J-20 uses F-117 technology; regards it as outdated

Following widespread reports Chinese agents bought F-117 parts from the jet shot down over Serbia in 1999, China has denied that F-117 technology was used to produce its new Chengdu J-20. A Chinese test pilot has said the F-117's technology lags far behind fourth-generation fighters and was regarded as "outdated" even in 1999.

J-20 uses F-117 technology?

I'd be surprised if this wasn't the case. Reports have emerged that China may have gleaned knowledge from a US F-117 Nighthawk that was shot down over Serbia in 1999. Croatian intelligence has indicated Chinese agents crisscrossed the region buying up parts of the plane from local farmers.

IMINT & Analysis has posted a satellite image from Google Maps/Earth of a F-117 mockup sitting on the ground at Luoyang China. Luoyang is home to the Luoyang Electro-Optical Technology Development Center, who is responsible for developing the current air-to-air missiles fielded by the Chinese military.
