The Czechoslovak Air Force redesignated its Fishbed-Js that had been re-engined with the Tumanskiy R13-300 engine as 'MiG-21MA', as they also were equipped with the RP-21MA radar. This example was TOC by the Czechoslovak AF in July, 1969 and retired in December, 1992 and is now on display in the small museum at Nitra.
