The crews of the Su-24M and Su-34 4A of the air force and air defence of the Southern Military District conducted refueling exercises in the airspace of the Volgograd region.

The refueling process was carried out at altitudes from 4.5 thousand m to 6 thousand m, with the speed of aircraft about 600 km/h, while the distance from the air tanker was less than 20 m.

Refueling of aviation equipment in the air from an IL-78 tanker aircraft is the most difficult element of flight training that must be systematically performed for training pilots.

The crews of the Su-24M front-line bombers and the Su-34 multifunctional supersonic fighter-bombers completed flight tasks for piloting aircraft on specified courses with a constant altitude and speed.

In total, more than 20 flight crews were involved in the work in the air. Refueling was carried out day and night, singly and as part of a pair.
