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".

Why no swept back wings? They had the plans for the 262 instead of using them it looks as though they crossed it with a shtoaravik
Do you think Uncle Joe was a little short upstairs because what comrade Yakovlev said about the Su-11 was just the same as he reportedly said about the Alexseev I 215.
Looks like when the soviets was taked the design plans of Me-262 was intented built a new aircraft based in that
Do you have any comments about this aircraft ?
