The Lavotschkin La-11 ( Russian Лавочкин Ла-11 , NATO code name : Fang , German: fang ) was a post-war Soviet fighter. With it, the era of piston-powered aircraft from the Lavochkin design office came to an end, after which only jet-powered fighters followed.
history
The La-11 emerged as a further development from the previous version Lavotschkin La-9 with the stipulation that the aircraft had a greater range. The aim was to be able to use the model as an escort fighter for bombers such as the Tupolev Tu-2 or the Tupolew Tu-4 . Accordingly, the fuel capacity was increased, the La-11 also lost an on-board weapon compared to the previous model, the aerodynamics were improved by laminar wings . Otherwise the two constructions differ only slightly. The range could be increased fourfold with these adjustments, but the flight performance of the machine suffered as a result.
The La-11 was no longer used in World War II ; the prototype did not complete its maiden flight until 1947. Rapid advances in the development of turbine engines quickly made fighter aircraft of this type obsolete. The Soviet Union made the aircraft available to friendly states such as China and North Korea, so it was also used in the early years of the Korean War . There the Lavochkins had little to oppose the modern developments of the jet age; the future belonged to jet-powered fighters like the MiG-15 or the F-86 .
During the Cold War , an American Lockheed P2V-3W VP-6 naval reconnaissance aircraft was shot down by two La-11s of the 88th IAP over the Sea of Japan on November 6, 1951 . The ten US crew members are still missing today. On October 7, 1952, a US Air Force (91st SRS) Boeing RB-29 was shot down north of the Japanese island of Hokkaidō by two La-11s of the 368th IAP. Previously, on April 8, 1950, a PB4Y-2 Privateer of the VP-26 had been intercepted by four La-11s over the Baltic Sea and shot down off the coast of Latvia . The ten-man crew were killed in the crash.
