"By 2020, the entire fleet will be replaced - each service arm," Army Gen. Vladimir Mikhailov said, adding that the process will be two-pronged, including the modernization of old systems and placing new aircraft on combat duty.
He said each arm of the Air Force has about 200 airplanes.
Gen. Mikhailov said the modernization of the entire front aviation fleet, including Su-24, Su-25, and MiG-29 fighters, was completed last year.
He also said the number of violations of Russian air space declined last year.
"The number of air space violations slightly fell, but the intensity of air traffic in neighboring countries, in particular the Baltic States, has increased," he said, adding there were nine violations of Russian air space in 2006.
