One of the largest air battles of the Second World War took place in spring 1943 in the sky over Kuban. The Germans undertook massive air raids to liquidate the menace from the rear, in which over 500 aircraft took part. But the Soviet aviation as well concentrated up to 900 machines in that place. A sharp battle lasted over two months. The fight for the air superiority was violent. The main role in this fight was played by the Soviet fighters of the new generation.
