more than one Su-47

[lucinator]

Was just browsing wikipedia and noticed that on the Su-47 page it lists there being four prototypes. I know wiki is not the most reliable of sorts but I was still curious as to whether there was more than one built.

To the best of my knowledge only one flight prototype. Possible more were built for ground testing.

The sole prototype built was also used for structural stress testing prior being made airworthy. During these test new prediction methods and calculations has been used to determine the structural strength of the aircraft without destroying the airframe.

There's often confusion on the SU-47 and S47.

There was however, only one flying Berkut.

The Su-47 is the S-37. What's the S47?

thanks, though I wonder where wiki got those numbers.

the wiki article contradicts itself - so its hardly a useful reference.
