          Based
            loosely on the Yak-3, the Yak-11 was
            the Warsaw Pact's main trainer directly after World War II. 
            First flown on 10 November 1945, almost 4,500 were produced by 1956
            including license built LET C-11s in Czechoslovakia.
             A tricycle landing-gear Yak-11U was also
            produced.  This aircraft remained in service with Soviet Air
            Force until 1962. 
            The NATO code name for the Yak-11 was
            "Moose"  |
