Continuing to improve their fighters, EDO SA. Lavochkin La-9 on the basis to build a new plane "134" (La-9M). The first flight was in May 1947 g. performed by test pilot AG. Kochetkov, converted to KB from the Air Force Institute. Five days later, at the Chkalovsky airfield had a second copy of the "134D" with greater range. It consoles were equipped with additional fuel tanks, as a result of a stock of fuel on it has increased from 825 to 1100 l.
Two experienced embodiment "134" plane and "134D 'differ from the La-9 built in the engine oil cooler hood and reduced to three the number of guns NS-23. ROTOR these modifications is a single complex. loopholes guns, oil cooler air intake were organically entered in the hood of the engine AL-82FN, which reduces in-flight total resistance machines.
The plane "134D", intended to accompany the bombers, I had additional oxygen cylinder and urinal. The seat was equipped with adjustable armrests and wide upholstered headboard. Weighting machines led to a reduction of flight data. In July 1947 g. Test pilots IM. Dzyuba and VI. Alekseenko completed two long-distance flights at different speeds. The technical range is determined by the condition, two air battles lasting for 10-16 minutes will occur in the flight route. One flight lasted 4 no 54 min, other - 2 no 47 min. Despite the continuity of the "134" fighters and La-9, tests have revealed more than a hundred new machine defects. But the car is still recommended for serial production with the name La-11.
Series production continued until 1951 city, all around it was released 800 machines in different embodiments. AT 1946 g. SA. Lavochkin summoned to the Kremlin. In the same year in this country skyrocketed first jet fighter MiG-9 and Yak-15. IV. Stalin asks a direct question Lavochkin: "What plane should be run in series, MiG-9 and La-11?"Semyon said Stalin: "I think, MiG-9 ». Stalin was clearly provoked Lavochkin, when in the course of conversation, the MiG-9 indicated the already modified La-11 and even "raw", Lavochkin but his opinion has not changed. Not everyone would have at the moment, at this level it has been capable of such.
AT 1948 g. I had the idea to use the La-11 fighters to protect the polar regions of the USSR. While in the North Pole area we worked several scientific expeditions of the Academy of Sciences of the USSR. It was decided to make the flight La-11 group on one of the floes, used by scientists. Three aircraft made a safe landing on an ice floe. After completing a few missions from the ice, they went back. After these flights, the La-11 began regularly keep watch for the protection of our northern borders. For this purpose, the aircraft had to install anti-icing system, improved navigation equipment and provide takeoff from neukatannym snow bands.
Fighters La-11, and even took part in the hostilities. AT 1951 g. by order of the Council of Ministers of China received 60 La-11 aircraft. They are Chinese and Korean pilots reflect the US air raids on civilian towns DPRK. There they won several victories over the American aircraft, but to win over B-29 and could not. After the Yankees were flying at altitudes of about 10 000 m, and to reach such a height, La-11 was required 26 minutes. The Soviet La-11 fighters participated in the interception of US reconnaissance planes. 8 April 1950 g. Link La-11 took off to intercept the target. US plane did not obey Soviet pilots, ordered him to go to the landing, and opened fire on. As a result, killing nine crew members.
