This former Indonesian Air Force MiG-21F13 (serial F-2153 or F 2153 or F2153, depending what source to researched) was transferred to the very secretive 4477th Test and Evaluation Squadron "Red Eagles" (based at Tonopah) as part of the black Constant Peg programme in the sixties. This MiG-21F13 was called the HAVE DOUGHNUT article with the 4477th and was flown by US Navy and US Air Force System Command pilots during its 1968 exploitation. Red 64 was possibly the first of several Fishbeds acquired via Indonesia and used by the USAF. It carried possibly once USAF serial "004".
