Russia holds  large-scale flight-tactic exercise on Kamchatka (peninsula in the Russian Far East).
In course of the flight-tactic exercise, fighters of the Pacific Fleet Naval aviation took off to repel aerial attack of the simulated enemy from the Yelizovo airfield.
MiG-31 fighter-interceptors were redeployed at the region of alleged border breaching by aircraft of the simulated enemy.
The servicemen performed qualification standards in loading the munition, taking off, and cooperation of flight crews and ground duty forces.
