Sukhoi Su-11 (I)

In late May 1947, flight testing commenced of a development of the Su-9, the Su-11 or Samolet LK, which was destined to be the first Soviet jet fighter powered by a turbojet of indigenous design. The fuselage of the Su-11 was fundamentally similar to that of the Su-9, apart from some structural revision, but because of the appreciably larger engines, the wing structure was extensively modified. The Su-11 was powered by two Lyulka TR-1 turbojets each developing 1300kg, these being mounted ahead of the main-spar. Armament was the same as that of the Su-9. Factory trials were completed in April 1948, but the TR-1 turbojet was inadequately developed and, like its predecessor, the Su-11 was handicapped by the suggestion that it copied German technology,. Aleksandr Yakovlev telling Yosif Stalin that it was no more than a "warmed over Me 262".

The Su-11, like the Su-9, had straight wings like the MiG-9 and Yak-15. Despite using native Soviet jet engines rather than captured German jet engines, the Su-11 was a technological dead end because, like the Su-9, it was a slowpoke compared to the MiG-15.

The Soviets may have used a captured Me 262 as the basis for both the Su-9 and Su-11, because the Su-11's fuselage was narrower than that of the Me 262. I remember that the Nakajima Kikka was also superficially similar to the Me 262 but differed in having a squared-off vertical stabilizer and was lighter.
