The Lebedev XI ( Lebed-XI , Russian Лебедь-XI ) was a Russian military aircraft .
development
The Lebed-XI was created in 1915 at Lebedev's Lebed factory through a slightly modified replica of a captured German Albatros double-decker. The model proved itself and so production was started in a total of six variants and different engines. The total number of pieces remained small, however, as development and production soon concentrated on the subsequent Lebed-XII .
