Talk:Su-47 Berkut/@comment-4420085-20111016014615

The SU-47 was never intented to be a "real" fighter jet for the Russian Air Force.Only designed for forward swept wing technology that they stole idea's from NASA's X-29.The SU-47 was to slow,was terrible in aerodynamic's and it's airframe was very hard to build because of it's wing design and it was a costly plane to build there for low number's would have been made IF it had been a real fighter but it wasnt.The SU-47 and SU-37 are ONLY technology demonstraitor's that no longer fly.
