You really expect random laymen on the interwebs to know about these sensitive details about top of the range fighter planes? Seriously? Its the same discussion on every freaking forum.

You have read it on some other forum and you come here and raise the same questions, even though you have most probably read the answers to these "questions" already. Whatever happened to originality.
Anyways here is your answer, for the last time ever, no more spoon feeding for you.
