Did Pakistan Transfer Stealth Technology to China ?

Well recently a Pakistan was once again accused of transferring stealth technology to China.The helicopter used in the OBL raid was a modified stealth helicopter.As per the Americans,Pakistan gave the Chinese scientists access to this helicopter.

First to decide the truth we need to take a look at the level of technology concerning stealth in China.China has recently made its stealth fighter the J-20.Though an excellent fighter but the “rumors” suggest that its radar cross section (RCS) is still higher than the F-22 Raptor USAF uses.Infact F-22 will still have the least RCS even when PAK-FA of Russia,J-20 of China and JSF F-35 lightning come in service.USA is the undoubted king when it comes to 5th generation stealth aircraft.

According to Chinese “4S standard” a 5th generation aircraft must have:-

-Stealth

-Super cruise

-Sensor fusion

-Super maneuverability

Now here we are discussing stealth,one can lower RCS and increase stealth by

-Hiding areas with big reflectivity (engine fan blades etc)

-Design

-RAM and Honey comb coatings

Now China has mastered the first two,even though chinese do produce their own coatings the USA has a bigger experience in the field so getting a RAM coating out of the USA is somewhat of a bonus.
