Lavochkin La-9/11


Along with the various Yak fighters, the Lavochkin La-9 and La-11 were commonly operated by the North Korean and Chinese Air Forces. Typical of later Soviet designed piston engine fighters, their armament was concentrated in the nose of the aircraft. Performance was generally acceptable by WWII standards, but woefully inadequate when faced with turbojet powered opposition. Much speculation has been engaged in by aviation enthusiasts as to how the late war Soviet fighters would have fared against the fighter aircraft of the western Allies. Well, if Korea is used as an example, the answer to that question is 'miserable'. Mustangs, Corsairs and the F-82 had little difficulty killing these Soviet fighters. Although fast and maneuverable, they proved to quite vulnerable to .50 caliber fire, and could not withstand more than a few hits from 20mm cannon rounds. Moreover, the Soviet style tactics and generally poor level of training only exacerbated the ineffectiveness of these aircraft. Typically, U.N. fighter pilots viewed the Lavochkins and the Yaks as 'meat on the table'. One remarkable aspect of the La-9 and La-11 fighters was their strong resemblence to the German Focke Wulf Fw 190, especially in planform (viewed from top or bottom).


As the last of the fine Lavochkin propeller driven fighters, the La-11 incorporated a laminar flow wing to reduce both drag and the onset of compressibility. Generally believed to be the equal of later American and British piston engine fighters, the Lavochkin was never able to establish that as fact. Today, most Russian aviation authorities point to the low training and skill levels of the North Korean and Chinese pilots as the prime cause of the aircraft's lack of success.
