The first flight of the Su-11 aircraft took place on May 28, 1947, and on August 3, the Su-9 aircraft, piloted by A.G. Kochetkov and Su-11, piloted by G.M. Shiyanov took part in the parade dedicated to the Day of the Air Force of the USSR.

At the end of August, in parallel with the factory tests, flight tests of the TR-1 engine began under a separate program. On tests, at values ​​of M = 0.71, the Su-11 had a tendency to dive, accompanied by a drop in loads on the aircraft control stick. In February 1948, the tests were completed. The flight test report concluded that: "The main performance data of the Su-11 aircraft with two TR-1s, obtained during the factory flight tests, correspond to the calculated data. The absence of TR-1A engines and the insufficient effect of TsAGI recommendations adopted to improve the aircraft's behavior at speeds corresponding to a large number of M make it impractical to further refine the aircraft. .... "

In mid-1947, a draft design of a modified Su-11 aircraft with two Dervent-V engines (a domestic analogue of the RD-500) was developed, which received the designation Su-13 in correspondence. However, due to the lack of stocks of production facilities at plant No. 134, the construction of the Su-13 practically did not begin.

A.S. Yakovlev on May 25, 1988, in his conversation with the famous poet and publicist F.I. Chuev. "... At the end of the war, I wrote a letter to Stalin that we do not want to independently deal with the development of aviation, and this pushes us to copy the German jet Messerschmitt-262, and specifically propose to organize the production of this aircraft in Saratov.

Stalin summoned us together with Shakhurin and said to him: "Are you suggesting to put Messerschmitt instead of the work that is currently being done on the development of jet aircraft?"

Shakhurin muttered something, and this decided his fate. And Comrade Stalin said: "To build Messerschmitt means to doom yourself in advance to lagging behind for many years. We do not agree with this, and you are wasting your work in this direction."

Then he called me one: "Well, Shakhurin, apparently is not able to move this matter. Let's get a new minister. Whom do you recommend?" I said - Khrunicheva. I knew him well. Then he was appointed minister instead of Shakhurin. Officially, Shakhurin, Commander-in-Chief Novikov and Chief Engineer of the Air Force Repin were removed and imprisoned for supplying the Red Army with low-quality aircraft. But I think that Stalin's anger was also caused by our lagging behind in jet aircraft".

In February 1946, the design bureaus of V.M. Myasishcheva, M.I. Gudkov, A.S. Moskaleva, B.I. Cheranovsky and A. Ya. Shcherbakov, and work on the Me-262 aircraft was discontinued.

Plant No. 26 in 1946-50. produced 1911 RD-10 engines (Soviet copy of Jumo-004).
