Is it true that the US Air Force operated captured MiG aircraft for evaluation under the codename Constant Peg?

Yes. A Wikipedia article on the 4477th Test and Evaluation Squadron states that the USAF squadron operated MiG-17s, MiG-21s and MiG-23s between 1977 and 1988 under project Constant Peg. No retrieved item contradicts this.
